Lava demon (boss)

Hey. Minecraft is lacking in boss battles so I thought of a nether boss. It could spawn in a special shine room in a nether fortress. It could shoot fire balls and summon blazes. When it dies it would drop new items the lava helmet, and boots. They can help walk, see, and live in lava. The demon will also have a magma block on its forehead that you have to destroy before you attack it.
