Chargerius (CHAR-ja-rius)A dangerous boss

I would like something like a mutant lizard/Godzilla that would spawn in a new biome (another idea) and be in a lightning shield and have eggs that would be hatchable and be your pet.

It would have 350 health and would occasionally discharge a lightning ring.It would also use its claws to deal fatal damage unless you have special armor.

Now this creature of terror has a ridge of crystals along its belly that act as a weak spot. If you strike them they will shatter one by one. 

I think this will be a serious addition to the game. It would make Minecraft more dangerous to those who want a challenge.Therefore I would like if it was included in the game.
