I've got a few characters, but I though I'd introduce you to Edward Shaw. He's a scientist by day currently studying Supers and their powers, and he's also a Super Hero himself, cursed with super strength which he hasn't learnt how to control fully yet. He really doesn't look the part of a Super Hero, and he knows it, but he is very much a nice guy, if a bit hesitant on occasions.
More importantly, he was a kid adopted out of the foster care system, and he was luckily enough to be adopted by a gay couple, so he's never really been in the closet. However I think they have a lot of similar experiences, and he'd be happy to make friends with Max and to help him out if he ever needed it- and as a scientist he has his own lab which makes an awesome place to hide from Simone but pretend he's doing school work.
