If you’re unfamiliar with billionaire inventor, engineer and entrepreneur Elon Musk, he is sometimes referred to as the real-life Tony Stark. Not only is he the CEO of both SpaceX and Tesla, but he has also engineered a next-generation rocket. Now you’re seeing the Stark similarities, huh?

Nonetheless, Musk visited the Late Show last night, as host Stephen Colbert was trying to determine if the South Africa-born businessman was a superhero or a super villain, speaking tongue-in-cheek, of course. Elon, however, was able to keep the comedic juices flowing, mustering up a nice joke himself when showing a clip of Tesla’s new robotic arm that automatically recharges your automobile. After, talk then shifted to Musk’s opinion that humans could indeed live on mars. He insists that we’d simply have to warm the planet up, which could be done slowly or quickly — basically, we either live in transparent domes for a while, or nuke it. And to the latter, Colbert responded cheekily with the super villain remark.
