The Pun Tyrant
Hmmm.... Defintely much better but body manipulation is a bit too broad for me to approve.Idea
How this? any better? I left it open to have the possibility to have forms further on, and I'll have the back story tell why he can only do as such with his quirk right now.
Quirk: Body manipulation - His quirk changes the physique of his body, change it's color, and can even limbs to it. Though at the time being he can only grow a few inches and arms. He uses this Quirk to take on a form he calls 'Asura' which he grows in size and a couple of pairs of arms to resemble a deity of strength, Asura and to increase his strength.
Special Moves: Asura's Rampage - While transformed, He let's out a furry of punches with his multitude of arm. A last stitch attack...or an overwhelming attack to show off power.
Might I suggest perhaps something based on say a strong image? Like something that leaves a strong impression on him (traumatic or admiration) and his body can morph into something halfway to it? As a base idea, of course.
It is a good thing though to stick to this simple first form at first. Later on, with QEP , you could acquire new forms.
