B-127, better known as Bumblebee, is the deuteragonist of Paramount Pictures' Transformers film series. He is Optimus Prime's protégé.
Far from being a drawback, Bumblebee's diminutive size is his greatest asset. He goes where no other Autobots can, stealthily evading sensors and alarms designed for intruders much bigger and brasher, making him an ideal choice for covert ops/insertion missions
Wisecracking, brash, and sometimes overeager, Bumblebee is nevertheless cool and collected in a tight spot, seeing options and possibilities where none readily appear.
If there's a weakness, it's that in command situations Bumblebee tries a little too hard, overcompensating for his lack of overall stature.
