Backstory: Robert was born into the poorest regions of Brazil, and its most recognizable place. But like most people, he didn't do much to combat it, he just played along with the scenario and let things flow naturally, this is what he called "the lazy period" in his timeline. At some point at the age of 15, Robert got captured by scientists, who wanted to rediscover Extremis and possibly make it better, and Robert wasn't the only one, numerous other people were captured as well and were experimented on. Robert wasn't enjoying much the idea of being experimented and wanted to escape, and he hated that nobody did anything to change their situation. Robert eventually got around to making a plan, got injected with Extremis and made his escape, alongside saving everyone present. Once he escaped, he realized something, that he couldn't have escaped the prison by just being passive, so now his mind set changed, hating how much of a passive observer he was, he now jumped the front lines to become the best version of himself he could. He eventually graduated universities all across the world in about the same rate as Tony Stark, started a small business of his own and became a super hero, named Exo, but as time passed, he lost many of his unique traits all replaced with a calculating behavior focused only on evolving.

Extra:

-In the MCU, Robert had to remove a tumor that was developed in the brain, which was making Extremis fail, however, this isn't present in the comics version.

-In the comics, he married Carol when she was Ms. Marvel, but divorced her after Civil War II.
