Good old Voltron. I remember having missle wars with my friends when I was younger, at my parents house. We would all bring over any robot we had that would shoot missles, and shoot each others robot.
MMMmmmmm...Voltron, Daltanius, Orguss, Jetfire, and few other characters I can't recall. Oh yeah, and Omega Supreme. We would just throw his rocket arm back and forth 'til someone got hurt.
