Nitros Oxide (Earth-6515)

"Greetings, creatures of this planet, I've come to compete. So you pesky Earth-slugs like to race, eh, hehehehe. Well I, Nitros Oxide, am the fastest racer in the galaxy. I travel the stars looking for creatures to test my skills. It's a little game I call Survival of the Fastest. Here's the way we play: I challenge the best driver of your world to a race for the planet. If your driver wins I'll leave your miserable little rock alone. But if I win I'll turn your entire globe into a concrete parking lot and make you my slaves. HAHAHAHAHAHA! Get ready to race for the fate of your planet!"
