Stinger (weapon)

Can fry anything except the guys he's shooting at.

Bumblebee's stingers are among the few energy weapons that Optimus Prime's crew have at their disposal. Capable of shooting out single blasts or concentrated streams of electricity, the stingers can easily go through rock, space barnacles, and any old Earth material.

Decepticon armor-plating? Not so much.

Wasp, who shares a bodyform with Bumblebee, appears to have much better control of his stingers. In fact, his skill with them earned him his name... and Bumblebee's lack of skill earned him his.
