Poseidon

Poseidon was one of the Ragnarok, originating from the Ruin Ark.

Appearance
Poseidon vaguely resembled a giant squid or the smaller Abyss type known as Kraken, but was several hundred times larger than the latter. It had a large head, with protruding purple eyeballs and a mouth full of teeth, and several hundred green tentacles. It also had blue blood.

When strengthened by Yggdrasil's power, Poseidon changed in colour to black with red lines over its body (like other hosts of Yggdrasil).

Abilities
Tentacles: Poseidon possessed several hundred tentacles that allowed it to attack many opponents at once. These tentacles were strong enough to crush Drag-Rides. When enhanced by Lunatic Call, Poseidon was capable of producing even more tentacles.

Tunneling: Despite having the form of an aquatic organism, Poseidon was adept at tunneling through the earth. It could keep its main body underground, safe from harm, while extending its tentacles aboveground to attack.

Smokescreen: Poseidon could produce a smokescreen from its mouth, similar to the ink used by real-life cephalopods.

Regeneration: Poseidon's signature ability. It could rapidly regenerate from any and all injuries so long as its core was not destroyed. The regeneration could be hindered by freezing the injuries, but Poseidon could circumvent this by tearing off the frozen sections of its body. The regeneration was faster for parts of the body closer to the head.
