RedFlash is loud and obnoxious, proudly boasting to be the most awesome spheroid around. He also has a hair-trigger temper, and is known to be an idiot.
About RedFlash
According to RedFlash himself, he comes from the Red Colony, a colony of spheroids much like himself. Though early on, people didn't think much of him, he made a claim to fame when he singlehandedly destroyed a sonic weapon that the Blue Colony was planning to use against them. However, it is unclear how much of this story is true.
