This reminded me of the awesomeness of Big Rig, and why he can destroy Superman and Goku easily with speed alone. This is a quote regarding the top speed in the game.

"12.3 Undecillion MPH (or 12.3×10^36 MPH) is 2.08×10^24 Light-years per hour. The truck would be traversing the width of the our entire universe 21.1 Billion times per second. The amount of energy required to traverse at those speeds (if it where even possible) the truck would literally be fueled by BigBangs and as it would pass through our universe it would tear all matter into a super heated plasma soup before annihilating it into pure energy. The Big rig would would also destroy the very fabric of space-time, and if you believe in the multi-verse theory, it would then pass over to the next universe and destroy that one as well."
