Yeah plus you would want to have a cost for that power... like if he does it too much he loses a grip on his sanity
but I wouldnt expect WWE to write on that level
It'd be easier to just let the man talk. Comment on how he wants to succeed as himself. That he doesn't want to have to revert to some other mentality to beat people, but sometimes enough is enough and it just ends up there. Let him have some tag matches where he goes as the Demon, they win, but it involves him basically destroying his partner as well as whoever he's wrestling. Show that he doesn't
want to lose it, lack any semblance of control and just try and beat everyone up.
Something. Because right now it doesn't let him exist in normal storyline because 'If he paints himself, it's instawin' is basically his character right now. And that's stupid.
They want to talk all this shyt about split personality... I dunno. Have one of the writers play Hellblade with Finn or something. Understand what goes on inside some people's minds when they are actively stuck hearing whispers, being pushed to something. Driven without wanting to go but being unable to prevent it.
But this is wrestling. And nuance doesn't work when playing to the cheap seats. So... fukk it.
