Sam "Snap-But-Also-Mostly-The-Falcon" Wilson's parents were both murdered, which would be par for the course in one of these origin stories, except Sam didn't decide right then and there that he would do all he could to clean up the mean Harlem neighborhood he grew up in. Nope, he joined the mob. And then he renounced his criminal ways and became a superhero? Nope again! After he tried to rip off his bosses, a super-Nazi brainwashed him into being a good guy as a plot to trick Captain America, and then he just stayed that way.
Unfortunately, his fashion sense didn't improve a whole lot.
Falcon is hardly an anomaly. Storm of the X-Men? Met Professor X while stealing his wallet.
Professor X turned around so fast that he broke his spine.
