The Nether Dragon is a Serpentine-Cuboid Dragon and boss mob which can be found in the Nether.
The Nether Dragon is initially found imprisoned in a Nether Fortress, in an impenetrable bedrock prison. The fortress only has a chance to generate the prison room if at least one Wither has been slain, but it doesn't matter if this is in the Nether or Overworld (or the End). There have been unsubstantiated claims that holding a Nether Star while loading new chunks causes the Nether Fortress to be more likely to generate this room. The Nether Dragon will be released if the player finds and destroys any of the blaze spawners in the fortress where it is being held.
Once the Nether Dragon is released, it's boss battle begins. It will let out a roar extinguishing any Nether portals in the Nether. The player can still reactivate them if they have flint and steel handy, but the Nether Dragon will continue to extinguish them if they are reactivated, often before the player can make it through the portal.
Unlike the Ender Dragon, the Nether Dragon starts the battle off on the ground, stomping around and breathing some fire, occasionally shooting a fire charge. Once it is hit at least 5 times, the Nether Dragon will take to the sky.
The Nether Dragon, though not as powerful as the Ender Dragon, is a very deadly force of destruction. It can shoot fire streams from its mouth or blast long-range fireballs at distant players, as well as doing melee damage. It is immune to all heat-based damage, including fire and lava. It can also be healed by Nether Crystals.
The Nether Dragon's main attacks can be effectively countered with a fire resistance potion.
