Network File: Captain Caveman
Status: No effort made to conceal his identity (Not that he could)
Marital status: Widowed
Born during the last Ice Age, the caveman called "Unga" by his peers was from a species offshoot of Homo neanderthalis who simply called themselves "The Tree People", do the ancient forest that dominated their territory. Extremely strong and durable, even by Neanderthal standards, the Tree People prospered until their valley was attacked by a horde lead by a warrior we believe to have been Vandal Savage. Though the Tree People fought fiercely and decimated the majority of Vandal's army through sheer brute force, they themselves were wiped out, including Unga's own wife and young son. Driven into a berserker rage by the loss of his home and tribe, Unga tracked down Savage's surviving men and attacked them, riding on the back of a mastodon! Before Unga could turn his anger toward the scarred leader of the horde, a strange storm whipped up as if by magic and a massive bolt of lightning struck the land.
At the point, the story becomes somewhat fuzzy, as Unga lacks much of the phraseology needed to fully explain how he came by his amazing powers. All he truly remembers is coming back to consciousness alongside his mount in a strange cave, faced by what he can only call a "shaman of lightning".
