Zetsubou-kun

Despair-kun is a skinny, but well built man wearing a red speedo and two light-blue socks. He is always wearing a brown paper sack over his head. Though the sack has two large eye holes in it, nothing on his face can be seen. His entire head is never seen throughout the entire series, with the exception of his eyes (they can only be seen when he is angry, and they are glowing red when he is like this). Like his name would suggest, Despair-kun is almost always depressive. During his introduction, he actually tried to commit suicide several times, but with no success. He also gets very angry and aggressive at times, with almost no warning at all. Like many of the other characters, he can also be a little random, as he attempts to join in the rebels hajikelist attacks. Unlike most of the characters in Bo-bobo, Despair-kun has no real powers. He is not a shinken user, but the random side of his nature would suggest that he is a hajikelist (but he only uses these abilities to enhance the other rebels nonsensical actions). Normally, he only fights by exchanging physical blows. (Source: Bobobo wikia)
