It's futile. The world will betray you. Why fight at all? Why risk your life for those who will persecute you later?

— Mephiles the Dark, Sonic the Hedgehog (2006)[1]

Mephiles the Dark (闇のメフィレス Yami no Mefiresu?, lit. "Mephiles of Darkness") is a major antagonist in the Sonic the Hedgehog series. He was the malevolent conscience, mind and will of the sun god Solaris. Mephiles was born during the Solaris Project when the experiments on Solaris split him into Mephiles and Iblis. After his birth, Mephiles was sealed inside the Scepter of Darkness by Shadow the Hedgehog (who traveled back in time using Chaos Control) but was freed ten years later during a skirmish between Shadow, Rouge, and Dr. Eggman.

After his release, Mephiles orchestrated a centuries-long plan to release Iblis from Princess Elise and rejoin with him, which succeeded when he killed Sonic the Hedgehog. He then re-merged with Iblis, remaking Solaris, but was defeated by Sonic, Shadow, and Silver, and subsequently erased from existence.


Mephiles has four forms. His original form was an amorphous mass of darkness, which emitted an aura and behaved similarly to liquid. In his second form, Mephiles appeared almost identical to Shadow the Hedgehog, aside from having green eyes with slit pupils, a pale-skinned muzzle with no mouth (though his muzzle moves when he speaks, as if he does have one), and the fact that everything that is red on Shadow is a grayish-green on Mephiles. Just like Shadow, he had rings on his wrists and ankles. His third and most iconic form was a crystalline, anthropomorphic hedgehog appearance with no mouth, nose or even feet. Instead, his legs ended in a purplish mist. His eyes also change color in this form, gaining reddish-pink sclera and lime green irises, while his quills were bushier and ended in white tips. Lastly, his hands, gloves and all, became crystalline like his arms, with the fingers now ending in white-tipped claws.



Mephiles was accidentally created during the Solaris Project, under the supervision of the Duke of Soleanna. In one of the Project's experiments, Solaris was split into two separate entities: Iblis, his raw power, and Mephiles, his cunning mind. As Mephiles was trying to escape the facility, he was sealed in the Scepter of Darkness by Shadow the Hedgehog, who had traveled through time by ten years before the events of the game. As Mephiles was sealed inside the scepter, he vowed that he would not forget Shadow and that one day, he would kill him.

Sonic the Hedgehog (2006)[]

In the intervening years, Dr. Eggman somehow acquired the Scepter of Darkness. In the present day, the Scepter was shattered during a struggle between Eggman, Shadow, and Rouge the Bat, and Mephiles was released. Mephiles absorbed Shadow's shade and transformed into a copy of Shadow; in doing so, he absorbed Shadow's powers as well. Upon gaining his new form, he then laughed in amusement at the irony about how he was resurrected by the shadow of the person who sealed him away before sarcastically thanking Shadow for releasing him. Realizing that Shadow did not know who Mephiles was (as Shadow had not yet traveled back in time to face Mephiles in the past), Mephiles transported Shadow and Rouge into the future.

Mephiles then sought to find the Chaos Emeralds in order to bring pain and despair to Princess Elise and release the "Flames of Disaster" (a.k.a. Iblis), who had been sealed inside Elise's soul until she cried. Mephiles intended to fuse with Iblis, reuniting them into a single entity, Solaris, their original persona.

To accomplish this, he traveled to the future and implied to Silver the Hedgehog and Blaze the Cat that Sonic the Hedgehog was the cause of Iblis being released, which led to the destruction of their world. Therefore, Sonic was referred to as the "Iblis Trigger" by Silver and Blaze. He sent the two back in time, having revealed his ability to them earlier when he told them that they needed to go back to the past to prevent Iblis's awakening, making them believe that killing Sonic in the present would save their future.

Along the way, as all three storylines progress, the three main characters discover how Mephiles was somehow involved in the incident which created the "Flames of Disaster", wielded by Princess Elise. Mephiles has a very pivotal role in all of the story-lines, throughout the course of the game. He has the most direct role in Shadow's story. He also has a major role in Silver's story, as he manipulates Silver and Blaze into attempting to kill Sonic so that he can finally fuse with Iblis. While he himself has a very minor role in Sonic's story, where he is only seen when Sonic, Knuckles the Echidna and Miles "Tails" Prower are eavesdropping on his conversation with Silver and Blaze that ends with them time-traveling back to present-day Soleanna, his actions are still very much prevalent to Sonic's story, especially with his encounters with Silver.

When encountering Shadow again, Mephiles attempted to break Shadow's will to fight and join him (much like Black Doom had previously tried) by revealing that in the current future, the world and an unwilling E-123 Omega would turn against Shadow and imprison him in suspended animation (while keeping his hatred for Shadow a secret). Thus, he attempted to convince Shadow to join him, saying they would both get revenge on the world. However, Shadow proved immune to Mephiles' tactics, saying that he would determine his own destiny, leading to a battle between the two of them. Though Shadow took the upper-hand, Mephiles knocked him into a wall with an energy blast and incapacitated him when he lowered his guard, but Omega intervened and drove Mephiles off. When Shadow (along with Silver after foiling his second attempt on Sonic's life) traveled back into the past at that point, he learned of Mephiles' true origin (while Silver learned that Mephiles lied about Sonic being the Iblis Trigger). Omega, meanwhile, pursued Mephiles. As he was being shot, the dark entity revealed to Omega that the latter was one that would imprison Shadow in the future, prompting the robot to shoot him with heavier artillery. Though stunned, Mephiles laughs and escapes from Omega before Shadow and Rouge arrive.

Shadow, Omega, and Rouge later encountered Mephiles in a desert temple, though they were too late to stop him from getting the Chaos Emerald there. Again, Mephiles offered Shadow a chance to join him, but Shadow, knowing Mephiles' true intentions, flat-out refused the offer. Mephiles was fought again and lost. After his seeming defeat, however, Mephiles proved immune to being imprisoned in a new Scepter of Darkness that Shadow tried to use on him, saying that it would not work on him anymore (he implies that the reason he was immune was either due to his time traveling by ten years ago to absorb Shadow's shade during the moment he was being sealed in the present timeline [English version], or simply because he has absorbed Shadow's shade and copied his power altogether [Japanese version]). Mephiles then uses two Chaos Emeralds to create an army of clones of himself. He then boasts to Shadow that he can't defeat him, and asks why he is even bothering to protect a world that will eventually turn against him. Shadow replies with: "If the whole world decides to become my enemy, then I will fight like I always have!" He then removes his Limiter Rings and destroys the entire army.

In the Last Story, Mephiles, having either escaped or simply survived the fight with Shadow, finds the purple Chaos Emerald. Possibly, rather than progressing onto the next scene, he traveled to the future to deceive Silver. This is not specified, but it would explain how he had the purple Chaos Emerald and the knowledge of Sonic at this point. But This would have meant that Mephiles re-assumed his non-crystalline form upon meeting Silver, and Mephiles did not interact with Silver when he first sent Shadow, Rouge and himself into the future at the beginning of Shadow's story. Eventually, however, after Silver fails his mission, he uses it to warp to Sonic and Elise's location shortly after they escape Dr. Eggman's exploding Egg Carrier. He blinds them with the Emerald's powers, and projects an energy spear that impales Sonic through his back, killing him. Elise cries over his death and, because of this, Iblis is released, allowing Mephiles to fuse with him and transform into Solaris. Solaris is soon defeated in the final battle against Shadow, Silver and a revived Sonic in their Super States before Elise goes back in time and extinguishes him when he was a mere flame.

Born and split from the experiments done on the sun god Solaris, Mephiles can be described as a sentient being of pure darkness, craving destruction against the world.[2] Mephiles is a heartless and cunning sadist with no sense of compassion or empathy, who will do anything to accomplish his goal of fusing with his split half, Iblis, who is trapped inside Princess Elise. However, despite his pride, he relies on manipulation and hiding in the dark, waiting for the right moment to strike.

Mephiles is completely calm, emotionless, falsely affable, and completely patient, all traits of his manipulative nature. He is not shown losing his temper or raising his voice, even when angered or injured. If Mephiles is angered, as it happened when Shadow refuse his offer to join him, he would be disappointed and hostile without losing his patience. His affable nature is also shown when he politely bowed to Shadow after taking his form in appreciation, though this likely was a mocking gesture.

As a being of darkness craving destruction, Mephiles is a nihilistic misanthrope. During his final battle against Shadow, he asked him why he bothered to fight him, defending humanity despite them persecuting him as a scapegoat in the future. Mephiles interest in people is mostly a means to an end, just like how he wanted to "help" Silver save the future by killing Sonic, when in reality he wanted to unite with Iblis; otherwise, he shows little interest on anyone but Shadow the Hedgehog, whom he personally hates for sealing him in the Scepter of Darkness.

STH2006 LAST Elise's tears 06

Mephiles killing Sonic, from Sonic the Hedgehog (2006).

Mephiles demonstrated some fortitude, such as when he willingly let Omega beat him into submission and even laughed sadistically when the latter intensified in his attacks after he implied Omega's role in sealing away Shadow in the future.

The Sonic 06 guidebook implies that Solaris, and by extension, Mephiles himself, had psychological wounds from the Solaris Project. Therefore, his actions in the game can be attributed to him becoming crazed after the experiments conducted on him by the Duke of Soleanna.[3]

In the Japanese version of the game, he occasionally places emphasis on "s" sounds in a manner similar to hissing sounds in English. He also uses the pronoun "Boku", implying that he has a youthful demeanor, although it is possible it is done as a mockery of Shadow, who likewise uses that pronoun.

Powers and abilities[]

STH2006 SH The resurrection of Mephiles 19

Mephiles using his time travel ability, from Sonic the Hedgehog (2006).

Mephiles is a being who may not have a material form at all.[4] He has a great deal of shapeshifting skills that allow him to turn into different forms of matter, like liquid or gas, or even take another person's appearance by absorbing that individual's shadow. Subtle differences are applied, however, such as a far darker shade of various colors, a pale complexion, and bestial green eyes. He can also grow stronger by absorbing shadows, especially if it comes from the same type of shadow as the being whose shadow he absorbed earlier outside of time counts him as a very powerful character in the series. This is especially evident with his second encounter, where he managed to effortlessly escape imprisonment from another Scepter of Darkness due to his present self having gone back in time absorbing Shadow's shade while the latter was sealing away Mephiles' past self (although in the Japanese version, he merely states that he could not be sealed again due to absorbing Shadow's power via his shadow without even mentioning time travel). When he emerges from his victims' shadow to confront them, he is also shown to be much faster.[5]

STH2006 SH Omega appears 02

Mephiles's energy sphere, from Sonic the Hedgehog (2006).

Mephiles can manipulate and move through time with an ability similar to Chaos Control. Whether or not this was due to taking Shadow's form through his shadow or it was one of his innate abilities is debatable; however, being one half of the time god Solaris, the latter seems more probable. In addition, he has enough control over his time manipulation to separate pursuing enemies, as evidenced by how he managed to escape Omega and Shadow after their first fight in the future. His primary offensive technique is a massive sphere of black energy spawned from his hands that home in on their targets. He can also use the energy spheres to move himself and others through time. Since Mephiles absorbed Shadow's shade, he has the ability to physically become the shadow itself, as seen in the first boss fight against him. Furthermore, he can alter his physical form to sink into the ground and merge with the shadow of another. He can also manipulate shadows to create "clones" of himself, although they are warped and imperfect without Chaos Emerald energy. He can also merge the clones together to make large shadow monsters.

Wmplayer 2016-08-25 18-58-45-961

Mephiles firing his energy spear to kill Sonic, from Sonic the Hedgehog (2006).

Mephiles can blast opponents away by firing shockwaves of energy at them. Mephiles' final attack used before fusing with Iblis to become Solaris was a beam of energy that he extends from his right hand to kill Sonic. He is also capable of flight.

Mephiles appears to be immortal, surviving every fight he takes part in, and whenever he is beaten he seems to just shift into his base form. Whether or not he is capable of feeling pain is unknown; although he reacts to taking damage during his boss battles with Shadow, he merely stood and allowed himself to be shot multiple times when confronting Omega at Wave Ocean. Indeed, when defeated by Shadow a second time, he also declared himself to be immortal and invincible.

Because he is the mind and will of Solaris, Mephiles is very intelligent. This is shown in his ability as a skilled manipulator, being able to easily manipulate Silver and Blaze into nearly getting his desired result. He is also shown to have adept knowledge on using modern technology, as evidence by knowing exactly which files in Dr. Eggman's computer to use when trying to persuade Silver to assassinate Sonic. This is most likely due to his apparently endless lifespan and time travel power allowing him to study the world around him for as long as he needs to.

Mephiles is very skillful in the usage of the Chaos Emeralds' reality warping capabilities. He can release unseen shockwaves from them,[6] have them instill visions in others,[7] blind opponents,[8] and warp the other six Emeralds to his location instantly using just one. Presumably in the latter's case, he utilized the Chaos Emeralds' magnetic properties to pull this off.

Mephiles's monstrous form[]


Mephiles's monstrous form, from Sonic the Hedgehog (2006).

Mephiles's monstrous form is a state that Mephiles reached after empowering his darkness with Chaos Emerald energy and fusing with his shadows. Creating a giant body that he controls. In this state, he can fire large lasers in addition to the increment in physical capabilities.


As a being made of darkness, Mephiles is vulnerable to light-based attacks, such as Chaos Spear, which render him immobile.[5] His shadow-merging skills are also not infallible as intense power can force him out of other people's shadows.[9]



Shadow fighting Mephiles, from Sonic the Hedgehog (2006).

Mephiles is fought twice in the Shadow Episode in Sonic the Hedgehog (2006), first in Flame Core (Mephiles Phase 1) and then in Dusty Desert (Mephiles Phase 2). In each battle, he uses his minions to overwhelm the player with numbers and assaults, though he uses them much more aggressively in the second battle. The player has to use the Chaos Boost to make Mephiles vulnerable to attack, during which he will fight using energy balls and illusions.


Shadow the Hedgehog[]

You have no desire for revenge. You only crave destruction. Your only lust is to to fuel Iblis until there is nothing left of time itself

— Shadow confronting Mephiles, Sonic the Hedgehog (2006)
STH2006 SH The resurrection of Mephiles 18

Shadow and Mephiles, from Sonic the Hedgehog (2006).

Shadow is Mephiles' primary enemy. When Shadow came to the time of the Solaris Project and sealed him, Mephiles held fear of Shadow for how easily he stopped him, but also promised, that one day he would kill him as revenge. When Mephiles was released from the Scepter of Darkness and took Shadow's shade to gain a new form, he laughed at the irony but still thanked Shadow for mistakenly releasing him, though he was surprised that he did not know him at that point.[10] At the time of their meeting in Flame Core however, Mephiles had changed his mind about killing Shadow and instead gained a fixation to turn him over to his side. He tried deceiving him into joining him in exterminating humanity, but Shadow refused and it came to blows between them.

In all their encounters, Mephiles showed great respect for Shadow due to his skills which only fueled his determination to convert him. Even in the final fight, Mephiles tried making Shadow join him. However, after Shadow bluntly rejected Mephiles' invitation, Mephiles decided to forfeit his crusade and expressed his disappointment in him before resuming his old mission to kill him.

E-123 Omega[]

You’re just a nuisance… Robot!

— Mephiles battling Omega, Sonic the Hedgehog (2006)

Omega attacking Mephiles, from Sonic the Hedgehog (2006).

Omega is another adversary to Mephiles after Shadow. They never met until the battle between Mephiles and Shadow. In their first fight, Mephiles thought that Omega was no match for him and saw him a "nuisance" only to get brutally beaten. When the two later fought each other in Wave Ocean, Mephiles mocked and taunted Omega with how he was the one who sealed Shadow in the future. Omega took this insult to heart, to the point that he intensified his attacks while Mephiles faded away laughing. Omega would later take his revenge in the final battle against Mephiles alongside Shadow and Rouge.

Silver the Hedgehog[]

You must eliminate the individual who has awakened Iblis. …The Iblis Trigger.

— Mephiles the Dark, Sonic the Hedgehog (2006)
STH2006 SL He's the Iblis Trigger! 01

Mephiles deceiving Silver, from Sonic the Hedgehog (2006).

Mephiles held little interest in Silver the Hedgehog as a person and only used him as a tool to further his ends. Using the hedgehog's desire to save his world, Mephiles deceived Silver into going back in time to kill Sonic by telling him it was the only way to ensure Iblis never appeared - in reality, this was the opposite of the truth. He deliberately separated Silver from his companion, Blaze, and almost got Silver to kill Sonic, were it not for Amy and Shadow. Along the way, Mephiles encouraged Silver to continue his mission unquestioningly, refusing to answer any of his inquiries. Once Silver discovered the truth about Mephiles and quit hunting Sonic, Mephiles decided to kill Sonic himself.


Finally, the seal is broken! At long last, I’ll be able to join with you! IBLIS!!!

— Mephiles shortly after killing Sonic, Sonic the Hedgehog (2006)
Snapshot 43 (8-25-2012 8-22 PM)

Mephiles merging with Iblis, from Sonic the Hedgehog (2006).

Mephiles' main mission was to free his other half Iblis from within Princess Elise and destroy time itself. To this end, he carved a path of deception and death, where he manipulates Silver, tried to convince Shadow to join him, and killed Sonic. Once he succeeded, Mephiles laughed in triumph before fusing with him. The extent Mephiles went to fuse with Iblis and the multiple plots he spawned for that singular goal indicates that Mephiles' only interest during his existence was to reunite with Iblis.

Sonic the Hedgehog[]

So that’s why he wanted me to kill Sonic before…

Silver the Hedgehog, Sonic the Hedgehog (2006)
STH2006 LAST Elise's tears 06

Mephiles kills Sonic, from Sonic the Hedgehog (2006).

The two of them have never interacted, but Mephiles saw Sonic as the key to releasing Iblis from Elise and manipulated Silver by saying Sonic was the cause of Iblis destroying the future and sent the white hedgehog to assassinate Sonic. But after Silver had learned from Shadow that Mephiles tricked him, he no longer trusted Mephiles and even befriended Sonic. During the last story of the game, Mephiles successfully killed Sonic and transforming along with Iblis into Solaris. Unfortunately for Mephiles, Sonic was restored to life and Solaris, the unified Mephiles and Iblis, is disabled by Sonic, Shadow and Silver in their super forms, and later erased from existence by Elise blowing out Solaris' flame.



In other media[]

Books and comics[]

Archie Comics[]

Main article: Mephiles (Archie)

Mephiles, from Sonic the Hedgehog: The Complete Sonic Comic Encyclopedia.

In the Sonic the Hedgehog comic book series and its spin-offs published by Archie Comics, Mephiles was born during an experiment that split his original being, Solaris, into himself and Iblis. He was later trapped by Shadow the Hedgehog, but was freed and sought to rejoin with Iblis and remake Solaris. He eventually succeed in his plan, but was stopped and erased from existence by Sonic the Hedgehog and Elise. An alternate version of Mephiles also appeared as a prisoner in the Zone Jail.


Mephiles' name is derived from Mephistopheles, the demon from the legend of Faust, and possibly after Mephitis, the personification of the poisonous gases emitted from the ground in swamps and volcanic vapors.

Mephiles may also be inspired by the false prophet in the Book of Revelations of the Bible as he works in the shadows and manipulates the characters into doing things that would only further his own goals. Silver's theme song, "Dreams of an Absolution," also calls him a preacher who lies which may also be a reference to this.

Another possible origin for Mephiles' name may be from Arabic, similar to Iblis' origins. Mephiles could refer to "Muffles" (مفلس). In Arabic, Muffles means "broke" or "a person with nothing." The term extends not just to material objects, but to everything non- material as well, such as good deeds, emotions, hopes, dreams. In religious context, Mephiles is a name for the devil (similar to Iblis) and it refers to him as having no good deeds, no hope for redemption, and no chance of salvation. Taken this in mind, and Mephiles' nature in the game, they would seem similar.

GEE plush Mephiles

Mephiles plush toy, by Great Eastern Entertainment.

A skateboard deck with a design of Mephiles was made by Finesse, and the same design was used for a fingerboard by Spin Master later on. In 2021, a plush toy of Mephiles was announced by Great Eastern Entertainment. In 2024, Jakks Pacific released Mephiles' first ever action figure in Wave 15 of their 4" scale line.


  • Mephiles is the only character in the Sonic the Hedgehog series, and in any other Sonic-related media for that matter, who has actually successfully killed Sonic.
  • In an interview conducted by Game Informer, Takashi Iizuka stated that they have no plans for Mephiles to appear in any future games, and that he was only useful for the narrative of Sonic the Hedgehog (2006).[11]
    • However, Morio Kishimoto later posted in a tweet that Mephiles could potentially return in future installments.[12]
  • According to the leaked script of Sonic the Hedgehog (2006), just after Shadow had used Chaos Control to stop time around Mephiles in the "Sealing Mephiles" cutscene, Mephiles was supposed to say: "I am... the sun. I transcend... time itself. A bridge to.. other worlds!"
  • Despite being the main antagonist in Sonic the Hedgehog (2006), he and Sonic never interacted together through the whole game, with the exception of killing him or the final boss.
  • Dr. Eggman had shown an interest in capturing Mephiles. He tried to take the Scepter of Darkness, and later when Shadow asked Eggman who Mephiles was, he said he would tell him if Shadow brought Mephiles to him. It isn't stated why Eggman wanted to capture Mephiles, but based on his actions in the game, it can be guessed that he had hoped to harness Mephiles' powers to travel through time if he failed to do so with Iblis, or that he needed both Iblis and Mephiles to completely control time, knowing they were the two halves of Solaris. This last possibility is the most likely, since the full Solaris is a being that exists throughout all of time, and Iblis does not appear to have any time travel powers.
  • Mephiles killing Sonic reveals that his lie about Sonic being the Iblis Trigger was actually partially true. Sonic's death would not stop Iblis's resurrection; instead, it would actually be the catalyst that would release Iblis from Elise's soul since the key to Iblis's freedom was an event that would cause her to become so consumed with despair that she would cry, as she had formed a very close friendship with Sonic.
  • Even though Mephiles appears to lack a visible mouth, the general area on his "muzzle" moves in and out as he speaks in a manner similar to an inflating balloon.
  • When Mephiles is in the future, he has a purple Chaos Emerald, but later he doesn't have it or doesn't use it for some reason until the last story. However since he can travel through time, his actions throughout the game could be in any unspecified order.
  • It is possible that Mephiles might have a low tolerance for aggravation, which can be seen when Shadow refused to join with him. The result of that was Mephiles changing form and during the following boss fight, as well as the follow up one later, snippets of dialogue suggest a more aggressive side, in which he will growl and even make threats. However, being that both fights are paired against Shadow and only Shadow, it's also likely that due to Mephiles' hatred towards him, that this was merely a display of hostility.
  • In his crystalline form, it's possible that his quills and ears, and for that matter, the rest of himself, is as pliable as it would be in his Shadow form, as several cutscenes show the quills bending and being influenced by movement, and in one scene, his ear twitches slightly.
  • It is interesting to note that in Mario & Sonic at the Olympic Winter Games, Shadow bears great resemblance to Mephiles after wiping-out in any skiing or snowboarding event.
  • It is unknown why Mephiles tried to go into the past to find Chaos Emeralds and trick Silver into killing Sonic instead of just using his purple Chaos Emerald to join with Iblis in the future. It could be because Iblis evolved so much he could not fuse with Mephiles, or to ensure that Sonic's death would still occur so that Iblis would continue to exist at this point in the future (it is also possible that he could not go back to the exact moment where he and Iblis became two separate entities because he was already present). It's also unclear as to why Mephiles tricked Silver into attempting to release Iblis by killing Sonic and making the princess cry, when Mephiles could have found princess Elise, killed her, and then used his Chaos Emerald to fuse with Iblis although, he likely specifically chose a method that would psychologically torture and torment many both to fulfill his sadistic enjoyment and eliminate any threats to his destruction of reality.
  • Ian Flynn has expressed the opinion that Sega intended the Time Eater from Sonic Generations to be a sort of reborn Mephiles, some portion of him surviving the defeat of Solaris and the paradox that prevented his existence.[13] However, no Sega statement is known to have been issued in response.
  • In the early script for Sonic Forces, it was going to be revealed that Eggman made Phantom Copies of Mephiles the Dark and would have used them at the Eggman Empire Fortress just prior to the final boss battle although they likely wouldn't have been onscreen.[14]
  • Mephiles is one of the four characters (along with Fang the Hunter, Knuckles the Dread and Bean the Dynamite) to have a suffix title that does not refer to his species. Dark refers to his evil intentions.
  • When Mephiles gains a new physical form he has trouble walking and his limbs were limp most of the time, but in all later scenes he walks normally and his arms are no longer limp implying that he gained more control over his body after his transformation.


  1. As a fragment of Solaris' mind, Mephiles technically was the same age as Solaris was. However, as a independently acting creature, Mephiles was only 10 years old, as a result of him being split off from Solaris during the Solaris Project 10 years ago.
