Re: the Transformed
They can't just kick him out of school for changing, unless there is reasonable cause to believe he poses a hazard to the other children. Which may or may not be the case. Perhaps concerned parents got a magic expert to testify to that effect. Then again, it may be easier to say that even if he wasn't kicked out, the whole experience became too miserable for him to keep going there - whether anyone meant him ill or not.
The pocket dimension idea definitely has potential, and I would like to see what you come up with there. "Dark magic" is fine but it may be a good idea to rename it to avoid conflating it with the Dark, unless that is on purpose. As for the transformation, I suppose that raises the question of how he found such a portal. There may be many answers.
When I read your original suggestion, I actually thought his mother may have had something to do with it, but if she is meant to be an anchor of normality in his life, that's good too!
Re: the Protégé
Yeah, while you can arrange to control some NPCs, it really is better for the mentor to be mine. Still, you do get to define him through backstory questions and any notes you have for me - I'll base the characterisation on what you give me.
New Atlantis is huge and has people from all over the world. I think that a rival martial arts school based there would definitely work. But for that matter, where is the master's martial arts school located?
Freak is always used to unleash one's powers - even if those powers are peak human abilities. After all, they still put you beyond the level of most people, and invoke the feeling of a gap in abilities - whether you like that gap or not. Spider-Man presumably could have high Freak and high Mundane - they may often pull you in the opposite directions, but it is possible to have both. But do remember that the Labels shift around a lot.
I'd say that Labels are narrative powers rather than reflective of in-game capabilities. A martial artist can be a skilled combatant but still have low Danger at the moment. That just means that, given their current outlook and mental state, they are unlikely to achieve their current goals through direct confrontation. Maybe they are holding back when engaging a foe and so fight less effectively, or maybe they take down one opponent but are too distracted to notice a bigger problem. A less skilled character with high Danger would still not have as much fighting ability, but might be able to make it count for more through sheer control or drive. The martial artist would still be able to take on bigger threats with less risk to themselves, though - the narrative has to account for such differences in skill. Does that make sense?
With the Mentor, I think it's important to think of the things he wants your character to do... If he expects your character to monitor the situation and avoid biting off more than you can chew, that sounds to me like he embodies Superior and denies Danger. Of course you should still be ready to fight, but rushing into battle isn't how you are supposed to solve problems... and if you accept that, it could make it a bit difficult for you to perform well in situations where direct confrontation is the best solution. There may be other ways to play it too, though. Perhaps his teachings emphasize defending others (Savior) and not thinking of yourself as truly superhuman (Freak).
Re: the Outsider - it is a bit odd, but I think the expectation is that they would refuse. After all, the Outsider wants to be here, for some reason or another. At least until they're ready to leave this life behind.
