Superman and Kryptonite (Anonymous Modder MC)

Mod Details:

Kryptonite ore is a naturally spawning ore. Use a pickaxe to mine it and smelt in a furnace. Once this is done, you will get a kryptonite ingot. The only craftable item using kryptonite currently is a sword. It will break after 3-4 uses but it has 500 damage. To summon superman, use a snow golem configuration with one craved pumpkin and 2 lapis lazuli blocks. Superman has 999 health and does 20 damage. Superman is naturally hostile. His drops are: Lapis Lazuli, Lapis Lazuli Blocks, Gold blocks, Redstone blocks and more. Batman is only naturally hostile to Superman and has the same health and damage.  They can also be summoned with creative menu spawn eggs. Both Superman and Batman are bosses.
