The MC is a Joker behind the scenes, with professional level acting skills, thanks to his abilities not only to copy powers, but also physical attacks, he can be a sword master, literally, observing one, obviously if his body is in the level necessary to withstand stress.
Become a Master in close combat.
One of the first skills that copying is recommended are:
Shadow or Dark ability. when things get dangerous and you need to escape. Or, just spy and infiltrate places. use it to store things etc.
Regeneration (You can copy NOMU, you can even steal other powers than Villain number one. I spend so much time collecting. He's poetic.)
Haki (2 out of 3 at least, or something similar. Will save you.
Identify devils from other powers. The girl is in the group of Heroes in cat costumes.
One that allows you to stick to the ceiling or walls. like the Chacka in Naruto. Why? just because it's great.
Elemental Magician.
