Punch, known in his alternate Decepticon identity as Counterpunch, is a fictional Autobot character from the Transformers series. He is a double agent who can switch between two distinct personas: the loyal Autobot Punch and the covert Decepticon Counterpunch. This makes him valuable for espionage, infiltration, and intelligence gathering. His role in the series centers on deception, secrecy, and undercover missions, often creating tension because neither side fully trusts him, but both can benefit from his unique abilities.
