Quote1 I am Brainiac-5. Half-computer, half-organic lifeform, all Coluan, and, not to brag, but a 12th-level intellect. My name is Querl Dox, but the Legionnaires just call me Brainy. Quote2

Brainy's real form

When Brainy was seven, his mother took him to see snow for the first time. He loved it and didn't want to leave, so she bottled the planet, to her husband's horror, so he placed three personality inhibitors on their son.[6]

At some point, Querl joined the Legion of Super-Heroes formed by Mon-El and they faced General Zod, Ik'Lofrai'iork, the Emerald Bloodeater and many alien hybrids that were created from labs. When the the Worldkiller Pestilence, now known as the Blight, used her powers to spread her decay across the universe and killed Imra's sister, the Legionnaires went back to the past to stop the Blight from destroying the worlds, but due to their ship malfunctioning, they spent 12,000 years in suspended animation until their ship was found in National City and dug up by the D.E.O.[7][8][9][10][11][12]

Living in the present

Brainy as Barney Fife.

Brainy helped Supergirl to fight against Reign and the Worldkillers. Due to Pestilence's death, his distant relative survived and created a plague to kill all A.I.s other than himself, making it impossible for Querl return to the future. So Mon-El invited Winn Schott to join the Legion to deal with this, while Brainy remained in the present working with the D.E.O..[8]

At some point, Brainy started dating Nia Nal, the ancestor of his former teammate Nura Nal.
