Warpath

Warpath, oh where to start, he's a loud, annoying, trigger-happy tank-bot, who is also a fond admirer of the gun in his chest. He is also probably crazy. He also speaks in onomatopoeia with words such as BLAM or POW.

On Cybertron
On Cybertron, he was among the most bloodthirsty Autobots ever, with him taking part in some of the most daring and ridiculous missions ever committed by the Autobot cause.

Shooting Autobots
At one point during the war, Warpath lost it and started shooting everything that moved. He massacred 10002 Decepticons and 12 Autobots in the chaos before he finally got to his senses and stopped. He was promptly forced to retire from combat for a while and this drove him even more mad.

Shadow Wars
Eventually Shockwave overthrew Darth Megatron and took control of the Decepticons and reformed them into the Shadow Minds. Warpath participated in the war alongside the Unity Allies. He pwned a lot of stuff during the war. He participated in the battle of Balmorra and managed to somehow blow up a total of 13213 factories. A lot of stuff got blown up. He survived the war to blow more shit up.
