Foggy was also from a world where there were gods (hi Thor) and superheroes and the like. Aliens as well. ...wasn't Thanos an alien? He had to be, right?
"Hello, Bruce Wayne," Foggy said, with a small smile. Luckily for the other man, Foggy was from a world where Batman didn't exist. Or else he would have recognized the man's name. "I'm Foggy Nelson," he offered. "It's always nice to meet a person face to face." ...well, sometimes. It depended on the person.
And no, his given name was not Foggy. At the moment, though, Matt was the only one allowed to know his given name. ...though he'd offer it up if someone really cared to know.
