Antihero
His real superpower is not actually superintelligence, well not the biggest advantage anyways. More like that advanced, lost knowledge that gets transferred to him as he goes on. And he immediately knows applications and what to do with it, a cheatsheet in a way. Others are just casually struggling finding what interests them, he on the other hand already knows everything he wants to know. Hopefully he does not slip up, because the life he feared being locked up would become reality otherwise
