Querl Dox (Earth-38)

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

- Querl introducing himself to Kara Danvers

Agent Querl Dox, nicknamed Brainy by the Legionnaires, also known as Brainiac 5 on the field, was a Legionnaire and later an agent of DEO. Due to his connection to the Super Friends, he replaced Winn Schott's position on the team due to his leave to the 31st century.

Crisis on Infinite Earths
During the Crisis, Querl calculated the estimated time needed for the Antimatter wall to hit the planet. Moments later, heroes of the multiverse arrived to help evacuate the planet. Brainy then communicated with Ray Palmer about the Quantum Towers and their usage, later claiming Ray is the only person who speaks "his language". Querl then followed J'onn and gave him the keys of the Legion Cruiser for the evacuation. As he return to the control room, his algorithm calculated the whereabouts of Jonathan Kent.

Querl, Lois and Sara then travelled to Star City 2046 of Earth-16 for Jonathan. As they arrived, Querl was tied up by Oliver Queen (Earth-16)'s arrows and was left on the ground until Lois untied him after finding Jonathan. During the reunion of Sara and Oliver, Querl stated that if they do not return to Earth-1, the extrapolator might not have enough energy to open a Breach. They then returned, only to see Oliver Queen (Earth-1) saying his last words to his friends.

During the aftermath, Querl settled the denizens of Earth-38 on Earth-1. However, he along with the rest of Earth-1 was destroyed by Antimatter on December 10, 2019.
