Flamewing

Flamewing is the final boss in the Nether. He is an enderdragon. He is fought at Flamewing's Lair, near the Nether Holdout. This boss fight has been proven to be harder than the Two Withers boss fight. He will fly through the ceiling, and it will seem that hes gone, but he will come out of the floor or one of the walls and launch you across the room, possibly into lava. When Flamewing spawns, if he doesn't delete his spawner, you are allowed to delete the spawner. It is near impossible to kill him if Flamewing double-spawns. This boss fight is ended when you kill him or  when you die .

Location
Flamewing is located at Flamewing's Lair, near the Nether Holdout. He is fought in the big room at the end, although the room will be extended through the boss fight.
