Comet was a clone trooper that fought against the Separatists during The Clone Wars. He fought as part of the Wolffe Pack, a squad of clones lead by Commander Wolffe and commanded by jedi general Plo Koon. He appeared in Guardians of the Republic. He was played by Cupcake.
While Comet had strayed off into the forest looking for a late night snack, a Death Watch soldier followed him. The Mandalorian then flew above Comet and dropped an anvil on him. Comet couldn't breath or speak because of the pain and shock he was in. The Death Watch soldier then welcomed him to Death Watch and shot him, killing him.
