The unnamed beings were a sapient species of brain-like organisms native to rocky world of Cerebella in the Bogon Galaxy. Because of their physical design, they relied upon mechanical suits to move about their environment unabated. They are oddly capable of speaking vocally, despite no signs of having a mouth.
Notable members include the B2 Brawler and Scorpio, both are who are famed galactic gladiators. Another notable member was Brainius, who is the long lost cousin of the B2 Brawler.
