Bumblebee

Bumblebee (known as Bumble in Japan, Moscardo in Portugal) is the “little brother” of the heroic Autobot faction, constantly striving to prove himself in the eyes of the taller, stronger robots that he respects - especially his leader, Optimus Prime. So strong is this admiration toward others, he takes risks that put him in danger. Although a bit of a wise-cracker, he is a capable and reliable messenger and spy, his small size allowing him to go places that his larger comrades cannot. He is highly fuel efficient, has great visual acuity, is particularly adaptable to undersea environments and transforms into a Volkswagen Beetle. He was later reconstructed in a stronger, more mature form as Goldbug.
