"I know you lost your whole world, your friends, your home. I miss what I had, too. I know what you're going through, how responsible you must feel."
"You don't know anything!"
Kara Danvers and Brainiac 5[src]

Brainiac 5 is one of the doppelgängers of Querl Dox that survived the Anti-Monitor Crisis.


During the Anti-Monitor Crisis

Brainiac 5 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.[1]

Arriving at Earth-Prime

"Why should this Earth live, when every other one DIED?"
—Brainiac to the Superfriends

Intending to unseal his Earth, Brainiac fought with his Earth-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.[1]
