FLATTOP is an Autobot cadet out to prove himself. In an attempt to make himself seem more important he often tries to convince his mates to volunteer for more and more dangerous missions, hoping for the quick path to glory. In F4 Phantom fighter jet mode, Flattop is designed and trained to work with Broadside, much to the latter’s chagrin. Although small in robot mode, in Phantom mode Flattop is a large fighter with a top speed of over Mach 2.2. Although heavily armed and highly educated, Flattop himself is unproven in battle, and in actual combat he’s as likely to freeze up as fight. He possesses intense survivor's guilt from something that happened to him in his Academy days, almost to the point that he now has a death wish that might bring down everyone with him.
