Chaos is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It is a Chao that mutated into a water elemental, which was responsible for all but wiping out the Knuckles Clan of echidnas. Imprisoned in the Master Emerald by Tikal, a girl from that tribe, Chaos remained trapped for centuries until it was released by Dr. Eggman. After accumulating power from the seven Chaos Emeralds, it attacked Station Square only to be stopped by Super Sonic. Following this, Chaos and Tikal returned to their home within the Master Emerald.


Chaos is a lifeform with a body made of water-like energy. There are numerous forms it can take. In its most recognizable one, Chaos possesses a humanoid form with disproportionally long arms and legs compared to its torso. It has thick forearms with three large fingers on each hand, a short stump for a tail, and long feet with two large toes each. It also has two fin-like protrusions on the back of its head, sharp flaps on each side of its head, and a tall bulge on top of its head. It also possesses no facial features, except for two pupil-less lime green eyes. Lastly, it has a round pink brain inside its transparent head, with a brain stem on the bottom.



Chaos was originally an ordinary Chao that lived in the altar of the Master Emerald and the seven Chaos Emeralds. However, after tapping into the Master Emerald, Chaos would harness some of the massive Emerald's Chaos energy that mutated it into what it is now. Using its newfound power, Chaos would protect its Chao friends and fend off foreign invaders.[1]

Around 3,000 years ago, Chaos and its fellow Chao met Tikal, who would befriend them almost immediatly afterwards. However, their Chao colony would be threatened by the Knuckles Clan, a powerful clan of echidnas that Tikal was a part of, which sought to invade the Master Emerald's altar to gain unlimited power. When the day had come, the echidnas launched a massive assault on the altar, despite Tikal's attempts to stop them. Seeing this atrocious treatement from the Knuckles Clan towards its friends, Chaos harnessed the energy of the Chaos Emeralds to turn into Perfect Chaos, wiping out nearly all of the Knuckles Clan's men. Now having its mind with nothing but anger and desire for revenge, Chaos would have destroyed all of Sonic's World had Tikal not sealed herself and Chaos into the Master Emerald, which would be protected by the few remaining members of the Knuckles Clan in the centuries to come. Chaos' rampage was documented in ancient texts in the Mystic Ruins, but would soon fade off as a legend.[1]

Eventually, in the recent past, Dr. Eggman learned of Chaos and its massive power. Wanting to use the beast to destroy Station Square and build Eggman Land on its ruins, the doctor shattered the Master Emerald and tamed Chaos while hunting down the Chaos Emeralds to help it grow in strength and size. However, Chaos eventually turned against its master and, as Perfect Chaos, attacked Station Square on its own with a devastating flood. Fortunately, the beast's rampage was put to an end by Sonic, who transformed into Super Sonic, defeated Chaos and neutralized it. Following this, Chaos reunited with Tikal and the Chao, and after learning that the planet's inhabitants were not so bad after all, returned to its home inside the Master Emerald.[1]

Chaos appeared again during a crisis involving Emerl, in which Eggman launched the Death Egg with a weapon of mass destruction that could destroy Sonic's World. During this incident, Chaos trained Emerl so he could become stronger to defeat the doctor.[2]

In a possible event of the Time Eater incident, Sonic would fight Perfect Chaos in his base form during the beast's attack on Station Square. Despite the odds, the hedgehog was able to defeat Chaos and adquire a Chaos Emerald.[3]

Worlds Collide

Note: Due to the Genesis Wave, Chaos' history was changed to be identical to that of its game counterpart's. See also: Chaos Devil.

When reality was rewritten by the second Genesis Wave, Chaos' history remained largely unchanged.[4] Much later, Chaos was reawakened again by Dr. Eggman and was merged with Dr. Wily's Devil Core to create the Chaos Devil.[5] The monster was accidentally unleashed by Rouge the Bat aboard the Wily Egg during her attempts to bring down the ship from within. It managed to capture Rouge and Metal Sonic v3.0 and was menaced by Bass, but the two doctors arrived and ordered it to release its captives. It did so, and Rouge was taken away to be roboticized, while the doctors prided themselves on the success of the Chaos Devil's operation.[6]

The Chaos Devil later appeared again to engage Sonic and Mega Man as they made their way deeper into the Wily Egg, but was engaged by the heroic robot Duo.[4] After a heated battle, Duo freed Chaos from the Devil Core and destroyed it, and the pair were then caught up in the effects of the Super Genesis Wave which in the end came to create a new reality with Chaos in it.[5]

Shattered World Crisis

Note: From the readers point of view, this picks up from where Chaos' original timeline ended.

After Sonic's World was broken up due to the Super Genesis Wave, Angel Island was rocked by the rising landmasses. In the midst of this commotion, Chaos emerged from the Master Emerald and dove down to the planet below where it kept the oceans from draining away from the planetary pieces.[7][8] It later appeared in the city of Meropis to aid the beleaguered defenders, among them Sonic and Rotor. Chaos battled the Dark Guardian and defeated it by manipulating the water around them. Working together, the trio dispatched the Dark Guardian, while the rest of the Dark Gaia Creatures were defeated by Coral the Betta, Tikal, and Pearly the Manta Ray reciting the Mystic Melody with Aquarius. Chaos' presence and the successful restoration of the city's energy shield renewed King Puff and Queen Angelica's faith in Coral's abilities, and she was reinstated as priestess of the Eusebes Shrine.[8]

Powers and abilities

Chaos is an incredibly strong creature whose power is so great that it is revered as a deity.[8][1] Moreover, Chaos has hydrokinetic abilities that allows it to control water to a planetary scale; even in its base form, Chaos was able to control the oceans of the shattered world to prevent the planet from drying away.[7] Also, being made of liquid energy, Chaos is nearly indestructible and can mimic the properties of water. It has complete control over its physical structure, allowing it limited shapeshifting, such as elongating its forms, change its shape into fluid liquid, and if dissipated, it can reconstitute itself again.


Perfect Chaos

Perfect Chaos is the form Chaos takes after absorbing the negative Chaos energy of all seven Chaos Emeralds. In this form, Chaos becomes a giant serpentine dragon-like beast with a mouth extending far beyond its eyes, which are now reptilian.
