Here is another character that, to be honest, only appeared in X-Men but is originally Canadian mutant who is a member of Alpha Flight. That is not all as there is something even more interesting about him. He is basically Marvel’s first character that prefers the same gender, who also, in issue 51 of Astonishing X-Men, married his husband. Northstar and the rest of the team were created by legendary writer John Byrne in 1983. Byrne wanted to take the Alpha Flight away from the X-Men, and in order to do that, he created more real life like backgrounds for the characters, including making Northstar a man that is attracted to other men. Back then, thanks to a harsh editorial policy, this could only to be hinted.
