Bumblebee is the youngest, yellowest, and most energetic of the Autobots...as usual. A hyperactive wisecracker, Bumblebee is quite convinced he's the fastest—and coolest—thing on four wheels. He has a tendency to bite off mais than he can chew, so it's a good thing he pals around with the massive Bulkhead. He does not take well to being called short, and his over-eager ways can get on Ratchet's nerves all too easily. Still, Bumblebee is good with people, as evidenced por his fast friendship with Sari Sumdac.
