Locke

Locke the Echidna is the father of Knuckles the Echidna and was a prominent member of the Brotherhood of Guardians. A dedicated Guardian, Locke often put the training of his son above wishes of his wife Lara-Le, which resulted in their eventual divorce. After Knuckles' training was considered complete, Locke left his son to defend Angel Island alone, while secretly watching him from within the secret base of Haven. Years later, after Haven was discovered by Knuckles, Locke took a more active role in his son's life. When the Brotherhood of Guardians went missing and Knuckles refused to return to Angel Island, Locke took up position of Guardian once more and protected his fellow Echidnas. Locke fell in the line of duty, sacrificing his life to free Knuckles from Doctor Finitevus' hex, enabling Sonic the Hedgehog to defeat Knuckles, who was currently Enerjak, and restore his free will.

Raising Knuckles
Knuckles' father and Sabre's son, Locke is the most unpredictable Guardian after Spectre and the most powerful after his son. Locke and Knuckles didn't exactly have a good relationship, as Locke lied to Knuckles about his mother and family. Locke was granted a dream by the Ancient Walkers, which showed him Knuckles in the future facing a terrible evil. Utilizing his technological genius, he subjected himself to genetic manipulation, enhancing his abilities and likely activating the genes that would reveal themselves in Knuckles. He later subjected Knuckles' egg to Chaos Energy, making him into a living Chaos Energy battery. Locke's decisions ruined his relationship with his wife Lara-Le, who divorced him and then married another Echidna named Wynmacher (Lara-Le and Wynmacher eventually had a son named Knecapeon Mace).

Over the years, Locke raised Knuckles, instructing him in such subjects as self defense, advanced mathematics, and other Guardian requirements. When Knuckles was ten years of age, Locke left him behind, seemingly dying when he walked through a wall of fire. Unbeknownst to Knuckles, the wall was in fact the concealed entrance to Haven, and Locke joined the Brotherhood in observing Mobius in secret.

Member of the Brotherhood
Despite their separation, Locke continued to watch from afar, aiding his son from Haven numerous times. When Enerjak first emerged from his burial under the ruins of Mount Fate, Locke helped to provide Knuckles with a hidden oasis of water after he was banished to the Sandopolis Zone. Afterwards, Locke helped his son and the Chaotix to defeat the Chaos-demigod by exiling him into space.

After the firing of the Ultimate Annihilator weakened the dimensional barriers and returned Echidnaopolis, the Echidnas and the Dingoes from their mutual pocket zones, Locke focused primarily on overseeing how events played out, allowing his son to demonstrate his skills as acting Guardian. As soon as he learned of the Dark Legion emerging from their imprisonment in the Twilight Zone, Locke contacted Archimedes to help prepare Knuckles for the coming battle.

Locke helped his son again during the battle against Master Mogul. As Super Sonic, Hyper Knuckles and Turbo Tails engaged against Master Mogul, having transformed by stealing the Chaos powers from Enerjak via the Sword of Acorns, Locke and other members of the Brotherhood channeled their Chaos powers and helped create the new Master Emerald, with Mogul trapped within.

During the most recent Day of Fury, Locke embarked on a solo mission to rescue his ex-wife Lara-Le, who had been trapped in a snow storm while attempting to get to Haven to speak to Locke about their son. Once he arrived, Locke explained that he didn't want to fight with Lara-Le and that he wondered if she truly knew him at all before kissing her. Following this, while flying back to Haven with Lara-Le, Locke rescued Geoffrey St. John and his expeditionary force from the Royal Secret Service, who had been caught up in the storm caused by the Day of Fury as well. Locke explained to St. John what had happened to Queen Alicia and Prince Elias during the Great War before dropping him off at Haven to retrieve the comatose queen. From there, Locke flew Lara-Le to rescue the crashed Echidna Security Team ship carrying Wynmacher, reuniting his ex-wife with her current love interest.

Not long afterwards, Locke and Spectre remained the only two Brotherhood members who had not been captured in the Dark Legion's sneak attack on Haven, Locke having been in the Master Emerald chamber at the time. The two proceeded to free their fellow Brotherhood members.

During the aftermath of the Dark Legion's failed scheme, Knuckles noticed Locke in the distance. Unable to out-run his son, Locke turned around and faced Knuckles in person for the first time since the latter was ten years old. Locke proceeded to give Knuckles a detailed history of the formation of the Brotherhood of Guardians, his premonition of the future granted by the Ancient Walkers, and the subsequent Chaos-experiments he performed on himself and later on Knuckles' egg before his hatching. The following, Locke provided information on girls and the Soultouch to help his son develop a relationship with Julie-Su. He then attended his son's surprise sixteenth birthday party.

Some time later, Locke and the rest of the Brotherhood were visited by Mathias, who predicted a serious attack about to occur from the Dark Legion. Locke participated in the Brotherhood's attack on the Dark Legion's stronghold at the Grand Conservatory, only to be sent to another zone when the Quantum Beam was fired at Angel Island from the Dark Legion's Battle Cruiser.

Upon their return to the prime zone due to Chaos Knuckles reversing the effects of the Quantum Beam, Locke was shocked to hear from Spectre that both Hawking and Mathias were no longer amongst the living. When Spectre mentioned the death of another unknown Guardian, Locke feared it was Knuckles, though his son soon contacted him via telepathy to inform him he was alright.

After the death of Knuckles due to another of Mammoth Mogul's schemes, Locke attended his son's funeral, aware he had moved on to another level of existence but still deeply upset at his son's death. Locke later informed Princess Sally and the others about Knuckles' death during the arrival of the Xorda.

Return as a Guardian
After the rest of the Brotherhood disappeared during a Dr. Eggman-backed Dingo attack on the Island, Locke joined forces with Lien-Da and the Dark Legion to resist the oppressors. He alone acted a Guardian until shortly after Sonic's return from outer space, when he was subsequently captured. Prior to being taken captive, Locke entrusted the safety of the Master Emerald to the Dark Legion. Lara-Le, though happily remarried, refused to allow Locke to suffer and so called Knuckles (who had returned from the dead) for help. Aided by the Chaotix and Sonic the Hedgehog, Knuckles was able to free his father and regain his lost Chaos powers. Unfortunately for Locke, he found himself Angel Island's Guardian again when Knuckles, forced to choose between his duty as Guardian and his obligation to fight Dr. Eggman on Mobius, decided on the latter, leading the two to become estranged once again.

In addition to protecting Angel Island, Locke began a desperate search for the rest of the Brotherhood, refusing to believe that they had died defending the Master Emerald. This led him to briefly hold Shadow the Hedgehog captive for examination, apparently in the hopes that Shadow's unique nature held the key to finding his ancestors, but the Ultimate Lifeform escaped and attacked Locke before leaving.

Following this, Locke led the reconstruction of Echidnaopolis. During this time, he ended up speaking with Rouge the Bat, unaware that her only intent in meeting with him was to learn a way to gain possession of the Master Emerald. Fortunately, Locke's old friend and mentor Archimedes teleported her to Knothole before she could take advantage of the Guardian, admonishing him and reminding the Echidna of his previous bad history with women. Shortly thereafter, Locke was once again distracted by Rouge, who attempted to lure him into a kiss while Evil Sonic stole the Master Emerald. Sensing danger when Sonic faced off against Evil Sonic near the Master Emerald, Locke left Rouge and saved Sonic during the fight.

Rouge and Evil Sonic would once again return in another attempt to steal the Master Emerald. While Locke caught them both, he proved unable to face them both at the same time. During the fight, Evil Sonic managed to absorb some of the Master Emerald's energy to become Scourge the Hedgehog, though Locke managed to knock him off in time to prevent a full super transformation, scarring Scourge's chest. With his new powers, Scourge managed to defeat Locke, but Rouge prevented him from killing the defeated Guardian. The two then transported to Knothole so that Scourge could test out his new powers against Sonic.

Following this, Locke became desperate to locate his ancestors, as the rebuilt Echidnaopolis had been destroyed and the Dark Legion split into two factions, resulting in civil war. With the Dingo regime constantly pressing their attacks, and Locke prioritizing locating the Brotherhood over his people's safety, he contacted Knuckles through the Master Emerald, telling him to return to Angel Island and help him to protect their people. Knuckles refused however, as he believed his goal should be to help the Freedom Fighters defeat Dr. Eggman instead. This resulted in a grudge between the two, after Locke said he could not ensure the safety of Knuckles' mother.

During A.D.A.M.'s attempt to summon all of the Chaos Emeralds in the galaxy, Locke cooperated with Doctor Finitevus, a mysterious albino Echidna who at one point served as Technomage of the Dark Legion, to keep the Master Emerald in its present location.

Locke arrived too late to help Echidnaopolis (which by now had been reduced to a primitive collection of huts due to repeated attacks) during a Dingo raid, though thankfully, Lara-Le was saved when the Destructix, at Finitevus' behest, fought back and saved the village. Finitevus claimed he wanted to assist Locke in his search for the Brotherhood, even having Dimitri to back up his claims. To this end, Locke was provided with a Warp Ring to continue his search around Mobius, but now had the capability to do this and return to his Guardian duties when necessary. Locke, seeing the population was celebrating with the Destructix, agreed and departed, unaware he was tricked by Finitevus into leaving so he could carry out his plans for the Master Emerald, to utilize it to re-create Enerjak.

While on his journey, Locke neglected to check in on Finitevus' activities as de-facto Guardian while on his quest, and so remained unaware that Knuckles, having returned to Angel Island in an effort to patch things up with his father and work together to repair the damage done to their home, had fallen prey to the hex placed by Finitevus placed upon the Emerald, and was reborn as the new Enerjak.

Enerjak's Return
Locke, his search having taken him to Albion, finally learned the truth about Finitevus, when he witnessed a recording left by Albion's High Councilor Gala-Na (which was discovered by Constable Remington). Originally a promising Chaos energy scientist, Finitevus was part of Albion's efforts to drain Chaos Knuckles of his immense energies, but as a result of interference from members of the Chaotix was transformed into his current state.. Finitevus, seeing the world as corrupt, resolved to wipe out all life, and, when Gala-Na ordered his euthanasia, helped the Eggman Empire to get access to, and destroy, the city. Following the recording, Locke left Remington in charge of the rebuilding efforts of Albion.

Returning to Angel Island, Locke soon found out his son was the reborn Chaos-demigod, but was powerless to reverse it as the hex placed on the Emerald blocked his access to it. Determined to fulfill his family's mission, Locke used the Warp Ring to abduct Sonic the Hedgehog and Julie-Su from New Mobotropolis shortly after Enerjak was captured by the Egg Fleet. His task for them was to get past the Destructix, whom Finitevus had commanded to guard a weapon created by the Brotherhood of Guardians in preparation for the possibility of Enerjak's return. Once in possession of the weapon, Locke had one intention: to end Enerjak's threat by destroying his own son.

Ultimate Sacrifice
Unfortunately, Locke's judgment proved poor once again, as even with Sonic and Julie-Su to aid him he was unable to get past the Destructix until Archimedes arrived to provide a brief moment of relief, and Sonic then destroyed the weapon, having never planned to go along with Locke's goals in the first place. Despite Archy's explanation that Knuckles' transformation was as much the Brotherhood's fault as Finitevus', Locke was unappeased and furious, but ultimately came to accept the truth. While Super Sonic did battle with Enerjak, Locke joined Julie-Su and Archimedes after they learned that someone would have to die in order to undo Finitevus' spell on the Master Emerald and free Knuckles. Determined to make amends for all that he had put his son through, Locke calmly walked to the Emerald, and performed the ceremony, causing the hex upon the Emerald to break and Locke was consumed in energy from the Emerald, causing him to die, leaving nothing but smoke behind. His life-force sacrifice complete, Knuckles was returned to normal.

Possible future
According to the alternate future of Mobius: 25 Years Later, Locke died at a rather young age given Guardian longevity, having apparently developed cancer (specifically a cancerous pancreas, due to his exposure to Chaos radiation while still an egg. Incidentally, this same treatment was performed on Knuckles, granting him the enhanced power he has for most of the series). Lara-Le and Knuckles visited him as he lay dying, and he confessed that he had realized the errors he had made during his life. He professed undying love for both of them, and told Knuckles how he regretted putting duty ahead of being a father. He died in his sleep in the middle of the night on the sixty-first day of the Mobian year 3246. Three days later, he was buried in a small, private ceremony, and as a result never met Lara-Su in that timeline. After Lara-Su's unveiling, Knuckles visited his grave, and came to realize that in denying his daughter the choice of becoming a Guardian, he was making the same mistake Locke had made with him. As Knuckles admitted his error, Locke was looking down on him in the company of Aurora, the goddess figure of Mobius.

Personality
Locke was a strong parent who cared about his son, but firmly believed that his affiliation with the Brotherhood and Knuckles' duty mattered more than his family, or even the possibility of his son's happiness. This led him to clash on more than one occasion with Knuckles, and Locke also had choice words with his ex-wife. She has since found another husband, and with him is raising a new family that Knuckles is considered a part of, while Locke isn't. Locke's single-mindedness and secrecy made any relationships difficult.

Abilities
Like all Guardians, Locke possessed numerous abilities derived from Chaos energy. As a result of his genetic manipulation, he had enhanced abilities, both physically and in Chaos. He was also a skilled technician.
