Crablante

Crabrante (カニランテ, Kanirante) is a Mysterious Being which was formed when a person ate too many crabs and underwent metamorphosis.

Appearance
Crabranate is a large creature with large, crablike claws and a hard carapace covering his upper body, while his lower body seems to be the same as a large males, with a pair of tighty whities on. He has two holes on his head that act as a nose, a rather normal mouth, and two eye stalks that protrude on the side.

Personality
Crabrante seems to have turned into a bloodthirsty monster after he turned into a crab, as he killed several people on his search to kill a boy who vandalized his body with permanent marker. He is proud of his "beautiful body" and turns very aggressive when someone defiles it. He seems to have some compassion though, as he let Saitama go just because they had the same lifeless eyes. When talking, he occasionally adds 'Blubblub' and 'lol' to the beginning and the end of his sentences, a verbal tic that indicates he is a crab that was once a man.

History
Crabrante appears before Saitama three years before the main storyline. They meet in the middle of a crowded street. Crabrante's appearance causes everyone apart from Saitama to run away from him in terror. He wonders why Saitama is not running away from him like all the other people, Saitama replies that since he is unemployed and unable to get a job he feels that nothing really matters anymore and thus he doesn't really feel like running away. At hearing this, Crabrante chuckles and says that Saitama's lifeless eyes remind him of his own and since he is after a different target anyway, a child with a cleft chin, he is willing to let him live and goes away.

Crabrante later appears in a park and discovers the child with the cleft chin. Just as he is about to finish him off the boy is saved by Saitama, who is also present there. It is revealed that the reason Crabrante wants to kill the child is because he drew nipples on his body with a permanent marker while he was sleeping in the park. He tells Saitama to not get in his way or he will kill him too, hearing this Saitama starts laughing which confuses Crabrante. Saitama reveals that Crabrante reminds him of a villain from an old anime that he used to watch in his childhood and that his childhood dream was to become a superhero who could beat villains like Crabrante with one punch. After a tough fight Crabrante is defeated by Saitama when the latter pulls out one of Crabrante's eyeballs.

Abilities
Crabrante possesses enhanced strength and was able to easily beat up Saitama (before he started training) as well as kill several regular human beings. Despite this, seeing as he was defeated by Saitama before he started his training, it can be said that he was fairly weak.
