Galius is of a race of aliens whose bodies are enormous heads, with normal sized legs and arms. He was first introduced fighting alongside Hal Jordan during the war against Krona and Nekron. He has participated in many battles alongside his fellow Green Lantern Corps, and served as part of the invasion force sent to Qward to destroy the Anti-Green Lantern Corps.[71] He was trusted to take part in the "psychodrama" in which Hal Jordan was tested on his capabilities of being a Green Lantern.[72] Galius survived the Crisis on Infinite Earths, but lost his power ring after the trial of Sinestro and the subsequent collapse of the Main Power Battery on Oa.[73]
