Redman

Redman is a psychopathic alien who kills Kaiju.

History
In 1972 he traveled to earth to hunt monsters. He soon started killing them one by one. A group of pacifistic monsters banded together to stop him.

Unfortunately, they failed and Redman killed them all. He still to this day roams the countryside of Japan. Killing each monster that gets in his way.

One day he spotted a group of peaceful monsters playing together and prepared to kill them, but was captured and put in prison by the Ultramen.
