Chaos King vs Mandrakk the Dark Monitor

Who wins?

Wasn't there two versions of Mandrakk? One full powered one and one depowered one?

At full power, Mandrakk should stomp effortlessly. Depowered, I see CK winning.

first mandrakk wins

second mandrakk loses

How will Mandrakk defeat him? The Chaos King had to be BFR'ed to a diff universe in order to "defeat him". That means no universal entity could stop him. Since BFR is not an option here.
