/summon lotr.Balrog ~ ~ ~ {HiredNPCInfo:{AlignmentRequired:-66666,CanMove:1,IsActive:1,HiringPlayerUUID:},Equipment:[{id:4492},{id:4468},{id:4467},{id:4466},{id:4465}]}

That's the command. You can command the Balrog, and it reacts to horns. The only downside is that it tries to kill you, but you may find it funny that it fails and does no damage. It still follows me in creative mode.
