#2 Finn Balor

Finn Balor's case is pretty peculiar. He became the first-ever Universal Champion and was forced to relinquish the title the very next day. Since then, he hasn't received his rematch either in the form of a one-on-one match or a multi-person match.
Given that the General Manager is a babyface, this should be enough to ignite a heel turn. Did we get it? No. Did he become stronger? No. Did he get buried? Hell yes.

These reasons should be enough to at least put him in the Multi-Person Match at Extreme Rules. The Demon King could finally have the heel turn which he has been teasing since his short-term alliance with the Good Brothers.
