In the long era of Cybertronian war, the time arrived where subterfuge was needed. The third of the Autobot spies was Punch.
An evaluation was done of his psyche, and he was found to have the perfect attributes to be a deep cover spy: an amount of friends that did not make it difficult for him to disappear. Deep love for causes he believed in. The ability to do whatever it takes to complete a mission. A level of thought that allowed him to segment the parts of his life so that he could function without guilt.
At least, that is what he thought...
Punch was completely successful in becoming a Decepticon named Counterpunch. Wheeljack and Ratchet were able to configure a second robotic form inside of Punch's body that looked completely different than Punch's main form. Counterpunch was not a spy - he started in infantry. Killed a few Autobots. Started to move up in the command structure. These activities did not affect Punch - it was for the greater good of the Autobots, he told himself.
Carefully, he fed information to the Autobots. Soundwave was the biggest block to doing so - he had spies everywhere. The situation became more and more dangerous until an operation so big and so secret was put into place by the Decepticons that Punch was forced to blow his cover and report to the Autobots. It was worth it - the plan was foiled - but the decision was made to retire Counterpunch. A fake body was put onto the battlefield that matched Counterpunch without ever bringing any suspicion on the reputation of "the valiant Decepticon commander."
Punch continued on with the Autobots, remaining active through the G2 and Armada years in an administrative function. During the Generations period, he was put back into active duty as a warrior. This did not last long, as he was crippled by severe processor malfunctions that left him offline for unknown periods of time. Optimus Prime took him off-duty.
Punch started to feel suspicious about his processors, and broken into Autobot records to find out his diagnosis, which Ratchet had continuously kept from him. The report was shocking - Punch's memory banks had segmented themselves into a readable sector and an unreadable one. When the Autobots tried to examine the sectors closer, more sectors destroyed themselves.
And somehow, Counterpunch had been seen again on the battlefield. Which was impossible - Counterpunch was gone. Punch could feel his processors crashing. As blackness overtook him, he had one final thought - is this the death of one life and the start of another?
