Yes, but it's a stereotypical personality, the un-stable histrionic maniac with superpowers. and I'm 100% it's done like that because "it looks cool"

If I had superpowers, I wouldn't be so emotional or theatrical in my behaviour...mainly because almost nothing could interfere with me, isn't it logical?

If I had Force Abilities I would do something similar to shake up my opponent. Also the foot stomping this could be only something he does when he is in the midst of combat. His personality can be far different from that in other circumstances.
