Brainiac 5 is a long-standing member of the Legion of Super-Heroes with a 12th level intelligence and force-field belt. He is an expert on the science of time-travel (and many other things).
In the 30th Century, Querl Dox was born on Colu, a direct descendant of the original Brainiac and Vril Dox II. After centuries of disuse, the title "Brainiac" was taken by Querl's father, and eventually was given to Querl at the age of twelve. He was the fifth to ever hold the title. Making many breakthroughs in the science of time travel during university as a young boy thanks to his mentor Circadia Senius, Querl was invited to join the Time Institute in Metropolis on Earth. He became close friends with fellow time genius, Rond Vidar. He invented the Time Bubble, which became the primary mode of time travel for the Legion of Super-Heroes. The background titled Space Laboratory was made by Dorianoart-d4jvi0z. Of course it was changed and toned down to fit the animation look better.
