Overworld Boss - Zombie King

INTRODUCTION:

I feel that every dimension has a boss except for the Overworld. The End has the Ender Dragon, the Nether has the Wither. Some would say that the Elder Guardians are the bosses of the Overworld but I have really only thought of them as a mini-boss of sorts.

THE BOSS:

My idea for an Overworld Boss would be the Zombie King. Basically, the mob would be an Iron Golem-sized Zombie who wears a golden crown and red cape (stereotypical king stuff). The Zombie King would have 300 hearts (the same as The Wither) and would have a life bar, that part is incredibly important. This mob would have an A.O.E ground-pound attack that would knock back the player and would cause damage. The Zombie King would also have a generic swipe attack. However, the real challenge of this Boss would be that The Zombie King summons zombies as you are fighting it. This wouldn't be limited to around 3-5 zombies at a time.

NEW BLOCKS:

To summon The Zombie King, a couple of new blocks would need to be introduced. The first would be a rotten flesh block. This would be crafted by, you guessed it, putting nine pieces of rotten flesh on a crafting table.

Next is a bit more interesting, you have to craft the Zombie King's crown. First, you would need a Totem of Undying. Then you would need 3 gold ingots, a diamond, and an emerald. To craft the crown you would put the 3 ingots on the bottom row, the Totem of Undying on the middle row, middle slot, and the diamond and emerald on each side. This would be a block., not an armor piece.

Crown of Undeath: G = Gold Ingot, X = Totem of Undying, D = Diamond, E = Emerald, O = Blank Space

SUMMONING:

To summon The Zombie King you build basically a Wither or Iron Golem shape out of the Rotten Flesh blocks and put the Crown of Undeath on top of the middle block. The boss would phase and instantly knock you back (no damage was done on this initial knockback).

THE REWARD:

All bosses should have an interesting and powerful reward for defeating them. The Wither has the Nether Star, which gives access to beacons. For the Zombie King, I think that the Crown of Undeath would be a fitting reward. This would now be an armor piece that takes place of your helmet slot. The Crown of Undeath would allow zombies to passive towards you as long as you are wearing the item. I thought about having all undead mobs be passive, but I feel that would be a little overpowered. This would be an awesome reward for a challenging boss fight as you could walk and work at night almost completely unopposed.
