PopTop is fully Autobot to the core. He is big, fast and powerfull. No one including PopTop knows how strong he is because he rarely ever fights. PopTop may look big and mean but he is the complete opposite. He would much rather read a book with a child or watch the butterflies that to ever fight. When he does encounter a Decepticon he can hold his own but if they are less intelligent he somehow manages to get them to go away without fighting. Many Autobots believe he has mental powers that he uses to confuse the Decepticons and make them leave. Because of his peacefull nature he has been teamed with Repugnus. Optimus felt PopTop would be able to monitor Repugnus and keep him in check. The tagteam didnt get along well at first but Repugnus has learned about keeping himself in check while teaching PopTop that fighting back is not allways a bad thing.
