New Boss in Minecraft

Dragon of the Waste: Dragon you fight in the nether that has a portal crafted from blocks from each of the 5 biomes of the nether and the 2 fortresses. Soul soil, warped stem, crimson stem, netherrack, basalt, cracked blackstone brick, and nether brick. When crafted in crafting table gives you an item that when used creates a portal out of recolored yellow netherbrick blocks with orange portal inside. When walked through creates an area primarily out of magma blocks similar in size to the end island with the end dragon. This one is surrounded by lava though instead of being suspended and has a cavern ceiling high above. The pillars are crying obsidian with recolored orange end crystals to heal the dragon of the waste. Dragon is recolored red end dragon with yellow eyes and same melee damage attacks. However, this one has the abilities of both the blaze and the ghast in dragon's breath attacks and when at half life splits into 2 smaller dragons. One has the fire charge, the other spews blaze fire. Health points is 200 x 200 so slightly more then end dragon. Dragon is faster and more aggressive then end dragon but hit box is slightly bigger. When killed drops experience orbs in volume similar to end dragon with new achievement and with portal to leave island. Maybe have chance to also drop loot upon death of dragon. Thoughts?
