This move will always kill the intended target and sometimes leaves Sam holding a 'trophy' which is usually some part of the enemy's body. The trophy can be dropped or thrown, although using it as a thrown projectile is fairly weak.
When it is Christmas, Sam can "decorate" the Christmas tree that appears in Summer in Cairo with each type of trophy, including a Gnaar's eye, a Kleer's skull, and a Rocketeer's heart.
Kleer Skeleton; Sam will sidestep and grab the Kleer in a headlock and promptly pull the Kleer's head off, leaving Sam with a held trophy.
Hatchling Arachnoid; Sam will break the Hatchling's neck, which instantly kills it. This move cannot be performed on the adult Arachnoid.
Scrapjack; this move can only be performed if the Scrapjack is stunned (he appears to be hunched over, but still standing). Sam will rip off Scrapjack's faceplate and kiss it, leaving Sam with a held trophy.
