I like the story but your dialogue tends to come across as too formal when characters are not speaking in a business setting, which in turns makes it kinda stale the best way to see this is say your dialogues out loud to yourself and listen to see if they come across as natural or too rigid. It’s easier if English is your first language or your very fluent in it. I’m not really sure about that, but good luck.
The powers are good. Invisibility and telepathy. And I have a feeling he'll get more eventually. But they seem pretty weak, and the limitations are pretty arbitrary. Only 15 minutes of invisibility, he can't turn it off and on at will, and an hour cool down between uses. And telepathy that he has to be totally calm and meditative to use, or else he's immediately mentally exhausted. Those are really weak, and don't really act like mutant abilities at all. They seem like computer game abilities if I'm honest, and not ones adapted to real life, but still based on computer game limitations. Hope that changes quickly.
