Bumblebee (G1)

Bumblebee is one of the smallest and physically weakest Autobots. He acts fairly young like a human in his late teens to early 20s. While his stature allows him to do his job better than most Autobots could manage, he is self-conscious about his size. Maybe this is why he makes fast friends among the humans. He looks up to the other Autobots, especially Optimus Prime. He's brave and courageous. He transforms into a yellow Volkswagen Beetle.
