Biography
“Evil Brainy” foresaw his earth’s impending doom and managed to safely trap it within a bottle before he escaped to the new reality of Earth-Prime.

Intending to unseal his earth, “Evil Brainy” fought with his Prime counterpart and his allies, desperately wanting to bring back his world despite the fact that doing so on Earth’s surface would likely destroy both worlds. Eventually, he was convinced to stand down, and he along with the other survivors of his earth sealed themselves in the bottle with it as well.
