This is a suggestion me and my friend came up with. It's a ghostly, floating thing:
The Endfestor
HP: 50 (25 hearts)
Damage: It spits balls of goop which deal 2 hearts of damage that takes over any mob but the Enderdragon, the Endfestor and the Endermen. The player is simply stunned by the attack. The goop takes a while to recharge, letting you crush it.
Found: The End (before killing the Enderdragon), and the Overworld (after killing the Enderdragon)
Drops: I'm not sure, but it could drop its goop which lets you take over certain mobs.
EXP drop: Should be pretty great, due to its rare-ness.
