Acid pellet

Prowl brought urine to a gunfight. No wonder Scavenger wasted him.

Acid pellets are small projectiles formed of acid. The Autobot Prowl uses a gun that is capable of firing acid pellets, as well as lasers. Scattershot wields an automatic acid pellet gun, which is also used by Computron. A burst from Scattershot or Computron will burn you. Up to 500 times per minute. Doubleheader's Pretender shell, not as much with its semi-automatic acid pellet pistol. As a 'bot not known for his subtlety, Warpath uses a similar weapon but on a larger scale: acid shells.
