Suggested by Destroyer Harry Potter may not be all that strong physically but his spells pack a punch. A direct hit may be enough to KO Daniel X. The same level of attack power can be said for Daniel X as well though and he has a significant advantage since he can shape shift and create whatever he wants. He has a much bigger array of attack options up his sleeve so I’d say that 9 times out of 10 he will claim victory. Daniel X wins.
