Nitro Zeus (Nitro for short) comes across as little more than a loudmouthed, trash-talking, strutting, self-aggrandizing jerk. He is all of those things, but unfortunately for his enemies, he's got the strength and skill to back up his ego. Though his manner makes his seem like a rowdy brawler, Nitro is actually more the stalk-and-destroy type. He is a powerful, merciless hunter, using his vast arsenal and formidable tracking skills to locate and capture whatever targets Megatron demands.
Even off the battlefield, Nitro makes it his business to know everything he can about where you live and who you associate with, just in case. Ever since Nitro was taken prisoner by humans, he's been passing the time by tracking his captors' families. Fortunately, Nitro is such a braggart that he'll share all his intel before he gets a chance to use it.
Shockwave's death on Earth greatly angered him, and now both humanity and the Autobots are in Nitro's sights.
