Zartan
Sometime after he began working as an assassin and mercenary, using his disguise abilities. Zartan also worked for a government agency under the name Amauri Sanderson. He underwent a top-secret French genetic experiment, which infused him with chameleon DNA, giving him the ability to blend into his background. During an arms deal with Destro, Amauri Sanderson met the leader of a motorcycle gang who was the original Zartan. Amauri joined the Dreadnoks and reunited with Zandar and Zarana. He was later approached by several Dreadnoks for the purpose of overthrowing the leader, who considered all the members expendable. When the insurrection was exposed, the leader planned to have Amauri executed by dismemberment. Zandar and Zarana incited a rival gang to attack, which gave them the opportunity to free their brother. The traitorous Dreadnoks teamed up with the rival gang, and Amauri fought and overpowered the leader and his rivals. With no one left to back him up, the leader was killed by Buzzer, Torch, and Ripper, and Amauri assumed the identity of Zartan.
