Tracer first appeared as a participant in the Meta-Brawl. When Green Arrow and Black Canary tried to extricate Wildcat, Tracer and the other contestants unsuccessfully tried to hold them off. Some time later, he fought alongside an unidentified group of villains, wreaking havoc on Gotham City. During the fight, Vixen conjured a boa constrictor and cut off his air supply. Tracer was presumably taken into custody after this.
The depicted subject bears the likeness of Tracer from the DC Comics; however, the DCAU character was never named on-screen, or otherwise. The title of this article is conjecture based on the character's likeness.
In the DC Comics, Tracer gained his powers as a result of experimentation. Like the other Extremists, he is based on a villain from Marvel Comics. Specifically, Tracer was inspired by Sabertooth, a mutant serial killer and enemy of X-Man Wolverine.
