An unnamed individual is a malevolent cousin of Querl Dox, who was referred to by the latter as the Evil One.
The individual created a plague to kill all A.I.s other than himself, making it impossible for his distant relative, Querl Dox, to return to the 31st century. This led to Winn Schott joining The Legion to deal with this new threat and save the A.I.s while Brainy remained in the early 21st century, working with the D.E.O.
Behind the scenes
- This character could be a reference to Vril Dox/Brainiac, a well-known adversary of Superman and the ancestor of Brainiac 5.
- Another version of Vril Dox appeared in the comics.
- If this is Brainiac, this would be the second time the character has appeared or at least been mentioned in a DC Comics live-action project outside of the cancelled Syfy series, Krypton where the character was the main villain of the series.
