Tracer
The first Tracer was a supervillain on the world of Angor, an otherdimensional duplicate of Earth. The Extremists wiped out Angor in a nuclear explosion, leaving only themselves and a few heroes who fled to Earth. The Extremists pursued them and it was revealed all but one of them had died and the surviving one, Dreamslayer, used androids of his comrades, including Tracer. They were deactivated and stored in the Watchtower. Tracer and his android duplicate demonstrated enhanced senses that made him an excellent tracker, enhanced strength and reflexes, a feral attitude, razor sharp claws, and enhanced healing.
