Avenger is an ARC Trooper Sniper assigned to the 698th Strike Battalion under the command of General Aurora Sunskimmer and Commander Nexu. He took on the name Avenger to show his commitment to avenging the deaths of his brothers at the mechanical hands of CIS combat droids. Each green tally mark represents a Separatist officer that he has killed, while the white tally marks represent the close calls he has survived on the battlefield.

He has the phrase "Up Yours Grievous!" stenciled on his chest plate.
