The new Gaius fight in the Praetorium has an enrage mechanic if you let his gauge fill up. Had a group let it fill just to see what happens before. It's kind of impressive when it goes off.

Ultima Weapon also has an enrage mechanic if you don't kill him before Ultima goes off. Those are both level 50. They're not based on timers but they function in the same manner to instantly wipe the party.
