Punch (aka Nightbeat[1]) possesses a unique transformation ability that allows him to adopt a second robot mode—posing as a Decepticon named Counterpunch to spy on the 'Cons as a double agent.

On the surface, Punch is a stoic individual that can take charge and keep others calm in a crisis. However, this is an act that hides how paranoid he's become. His responsibilities as a spy, in addition to the things he's seen among the Decepticons, have made him a mess internally.
