IV - The Emperor? is an unlockable consumable in The Binding of Isaac, added in the Repentance DLC.
Teleports Isaac to an extra Boss Room that is not part of the floor layout. The room is chosen from the boss pool 2 floors deeper than the current floor (cannot be a final boss).
Defeating the extra boss will spawn an item normally, but no trap door or Devil/Angel Room can appear there. Isaac can exit the room normally to get back to where he was previously.
