Sonic Bomber is the youthful, energetic and happy-go-lucky second in command of the Autobots. He looks up to his Supreme Commander, Dai Atlas with respect and admiration. Though brash and cocky, Sonic Bomber knows when to shut up and do what he's told. When he is combined with Dai Atlas, they become Sky Powered. However, when he's combined with Dai Atlas and Road Fire, they become the all-powerful Big Powered. He is paired with his Micromaster partner, aptly named Sonic.
