Bruinado

Crazy Brown Bear (also known as Bruinado) was a Demon-level monster who appeared in the snowy mountains. He was killed by the combined efforts of Superalloy Darkshine, Metal Bat, Genos, Speed-o'-Sound Sonic and Saitama.

Appearance
Crazy Brown Bear resembled a shadowy figure inside the body of a large brown bear. All that could be seen was a glowing face inside his mouth, like someone in a costume. Despite being named "brown bear", his fur is in fact red.

Zombieman Murder Case 2
Crazy Brown Bear first appeared in a snowy mountain range, and several S-Class heroes including Child Emperor, Zombieman, Superalloy Darkshine, and Metal Bat were dispatched to deal with him. They had no luck finding him and were forced to stay in a lodge for the night.

While the heroes were working on solving the mystery of who attacked Zombieman, they decided that Crazy Brown Bear could be responsible, or that he could be controlling one of the heroes' minds. However, the Hero Association informed them that his abilities were only punches and kicks.

Once the group deduced that the situation was just an accident, Crazy Brown Bear kicked down the door to the lodge and announced his presence. However, he was quickly defeated by the beleaguered heroes.

Abilities and Powers
As a Demon-level threat, it can be assumed that Crazy Brown Bear was fairly powerful. Several S-Class heroes were sent to face him, though this could have been because of the environmental conditions. The Hero Association claimed that despite his attacks only being punches and kicks, he was still a strong fighter. He was no match for the combined might of the S-Class heroes, Saitama, and Speed-o'-Sound Sonic.
