Concussion weapon

Concussion blasters are a type of weapon that cause the bulk of their damage through sheer physical force. For whatever reason, they appear to be used almost exclusively by Decepticons. Soundwave uses a concussion blaster with its own adorable battery altmode. And while Stranglehold's manly Pretender shell gets its job done with a brawn blaster, the tiny terror lurking inside prefers a concussion blaster in both robot and rhino mode.

Ransack uses a high-intensity concussion blaster when he isn't eating, kicking, shredding or shocking his enemies, and Sixshot totes a pair of similarly amped-up hypersonic concussion blasters, which presumably use soundwaves to do their job.

Razorclaw has a twin concussion blaster that knocks his opponents down with capsules that add injury to injury by releasing a volatile gas.

Perceptor bucks the Decepticon trend, using a concussion rifle when he finds himself facing a problem without a solution in the back of the textbook.

Living up to his name, Breakdown totes a concussion cannon that instantly causes mechanical failures in whatever it hits. While the vibrations from his engine have the same effect, he can pick off his targets more easily with this gun, and it's more potent. Only marginally more pleasant to encounter is Over-Run, whose Attack Copter transforms into a concussion cannon emplacement. Also the cannons can fire magnetic missiles. Because that's just how Over-Run rolls.
