Urn Eel

Urn Eel was a Demon-level Mysterious Being from the One-Punch Man OVAs. He was killed by Puri-Puri Prisoner.

Appearance
Urn Eel was a large eel-like creature. He stood upright, his body extending from the inside of a white and purple urn. He possessed brown scales, webbed arms and legs, and a large mouth full of sharp teeth.

Puri-Puri Prisoner and the Jailbreaking Prisoners
Urn Eel was part of the Seafolk's invasion of the surface world. After the invasion was stopped by the Hero Association, Urn Eel managed to escape and live in hiding.

Urn Eel had set up a hideout in an abandoned house in the countryside. Several escaped inmates from Smelly Lid Prison hid in the house while he was away. Once he returned, Urn Eel decided to eat all of them for intruding but was stopped by the arrival of Puri-Puri Prisoner, who easily defeated him. Urn Eel stood back up for round two, refusing to be beaten by a pervert, but was killed anyway.

Abilities and Powers
As a Demon-level monster, it can be assumed that Urn Eel was fairly powerful, but Puri-Puri Prisoner estimated he was more like a Tiger-level monster. His fighting style is unknown, due to how quickly Puri-Puri Prisoner dispatched him.
