By now, many of you have seen Iron Man 3, but now it's time to step back and think for a second: Who is this Tony Stark, anyway? Could PayPal co-founder, techno-entrepreneur and Tesla and SpaceX innovator Elon Musk be his real-world twin?

Here's food for thought: this infographic lays out the stark similarities between these two dudes. Come to think of it, they are of similar age, height, weight, and hey, both of their names end with a "K."

Those similarities are too superficial, though. You'll have to take a close look at the infographic below to get the full scoop, ultimately realizing the uncanny similarity between the origins, careers, innovations and education of Stark and Musk.

One thing's probably true — Musk, who's graced us with his presence right here in the Mashable offices for an interview, is a billionaire, but he would have to be a trillionaire to take Stark's technological leaps.

Meanwhile, back in the real world, Marvel comics found a dozen potential real-life Tony Starks in the making with its Iron Man 3: Inventor and Innovator Fair. That event took place on Friday, May 3, the same day as Iron Man 3's release, earning $60 million just on its opening day.

Robert Downey Jr., who plays Iron Man, surprised the 12 finalists on stage at the Innovator Fair, and said, "I'm humbled. I congratulate all of you."
