Mob (Mob Psycho 100) vs Steven Universe (Steven Universe). If you have a UniVS template with a picture of the two to replace the pictures, feel free. Comment your opinion on who would win and if you'd like to see this as an episode.
These two are young boys with powers they are still getting the hang of. Their powers often come from their emotions and they learn to deal with these emotions while also dealing with their powers. They are both often underestimated and envy the people around them, but have someone close that envies them.
I'm a little torn on this one, but on the spot I'll go with Mob. Mob almost always holds back, and every time he doesn't, he easily takes care of people that are likely city block to multi-city block level, meaning he's probably well above that.
