Cannon God Exaxxion

Hoichi is Kano is a typical Tokyo teenager...except that he pilots a state-of-the-art integrated gunsuit and the antimatter-powered, cannon-toting, mega-robot Exaxxion, plus he may be Mankind's last hope against colonizing aliens. But other than that, absolutely typical. Luckily, these extras will make matters a bit easier when he has to rescue his high-school crush - and his Mom! - from alien imprisonment. Of course, he may have to spend a bit of time explaining about his sexy shape-shifting android assistant, and he might need to do some image damage control after he levels a building or two, but that's nothing a typical teenager couldn't talk their way out of, right? I mean, it isn't like he stole a car or something!
