"One Is All" — the Ouroboros from the alchemical text Chrysopoeia of Cleopatra

The symbol of a serpent eating its own tail, making a circle.

Dating back to Ancient Egypt, the Ouroboros is a symbol of eternity and the cyclical nature of time and the universe. The fact that the serpent is eating itself is also indicative of the idea of self-consumption in the way we live. Sometime it may even be two serpents each eating the other's tail, taking on similarities with the Yin Yang symbol. Another, more modern common variation is for the snake or snakes to have an additional knot which forms the infinity symbol, ∞.

The Motif gains a lot of a secondary tier of association with alchemy and Time Travel. Note the connection to The Phoenix and also the serpent as the shedder of skin and rejuvenator which acts much like The Phoenix motif.

In some versions, the serpent encircles the world or the Tree of Life, and is tied to its fate.

  • In Battle Angel Alita, Desty Nova has a Lotus-Eater Machine he has named the Ouroboros program.

  • Kenichi: The Mightiest Disciple: The Eight Deadly Fists of Ragnarok have Ouroboros surrounding the Roman Numerals on their gloves.
  • In Mon Colle Knights, Oroboros is the master of the seventh realm, time, and as such it is an inorganic lifeform. It "appears" through the center of a gate that is the mathematical infinity symbol, and the Big Bad intends to use it to make everything one.
  • Noein: This motif crops up a lot, usually signaling that the amount of crazy quantum time travel hax is about to get even worse. The giant one that occasionally appears by a nearby island even serves as a portal to (effectively) The Legions of Hell near the end of the series.

  • Tiger & Bunny: A crime syndicate calls itself Ouroboros; members can be identified by ouroboros-symbol tattoos. For a while, Barnaby believed they were responsible for his parents' deaths, but they turned out to be a red herring. While it seems like it is unrelated to the motif of the Ouroboros, Ouroboros is in fact fed by Maverick, who essentially leads the heroes. His actions cause Ouroboros to become a real shadowy organization as well, and they are essentially unstoppable, vowing to return at the end of the series.
  • Souten Kouro, and adaptation of Romance of the Three Kingdoms focusing on Cao Cao, starts with depiction of the Ton, a mega-massive grotesque snake-like/dragon-like/crocodile-like beast that eats the world.

  • The Chrysopoeaia of Cleopatra, which provides the page picture, is an alchemical text that dates all the way back to 2nd century Alexandria. "Chrysopoeaia" means rather literally "Making Gold" or basically, since you're dealing with alchemists here, transmutation into gold i.e. a Philosopher's Stone. You can also see from the light dark comparisons the similarity to the Taijitu.

  • Discworld:
    • Tethys, the water troll, landed on the Disc after falling off another world. One of the worlds he passed had a giant serpent eating its own tail around the disc, instead of the turtle/elephant arrangement of Discworld itself. This may be a reference or either the Norse mythology of Jörmungandr or, due to it also appearing in connection to the turtles-elephants-world model, Adisesha of Hindu tradition.

  • The Worm Ouroboros is a High Fantasy novel by Eric Rucker Eddison.

To reflect this, they've all taken on names that represent some form of infinity, including Dr. Borous, shortened from Ouroboros.

  • Golden Sun: Dark Dawn has the Ouroboros Labyrinth. It's not as big a labyrinth as it sounds.

In its second appearance during the final stage, it actually starts circling itself in place, making it look just like the symbol it is based on. Ouroboros Mk.III from the 2014 ''Strider'' is a Shout-Out to it. Ouroboros also just happens to be Hiryu's best known Hyper Combo from Marvel vs. Capcom, though it was likely named due to the Hyper's nature (two bots constantly spinning around Hiryu) rather than as a callback to the boss.
  • In Swarm Simulator: Evolution, the final and most powerful production unit is called the Endless, and it resembles a cosmic ouroboros made of ascended swarm units.
