#4 Bray Wyatt
While he hasn't actually been a part of a single Money in the Bank Ladder Match, Bray Wyatt would have made for a fantastic holder of the coveted briefcase. He has been the creepiest member of WWE's full-time roster and the briefcase would have added so much more to his act.
The Fiend is past the Money in the Bank stage now, going after who he wants at will, but a Money in the Bank victory for Bray Wyatt would have been huge in around 2015. He was known for showing up unexpectedly and looming over his targets with sadistic intentions.
Bray Wyatt as Mr. Money in the Bank would have been gold back then, with his creepy promos and menacing 'Family'. You wouldn't know when he would strike, making the Eater of Worlds much more of a threat.
Wyatt was, and still is, the master of mind games. And isn't that the best part about holding the Money in the Bank briefcase? Playing mind games with the WWE Champion, before cashing in and winning the title.
