Nether Dragon

This doesn't exist in Minecraft; it's just fiction

Nether Dragons or Lava Dragons are Dragons that are found in the Nether near Nether Fortresses in Lava Oceans and in Khuton. They Cannot destroy Nether Bricks, Netherracks and Obsidians. Like Fire Skaidron, They are very large and tend to have a fiery temper, being easily angered by the slightest thing the player does. They snarl and roar often and screech when hurt. They can enter Nether Portals and Possible World, thus making it possible to have a Nether Dragon in the Overworld. Similar to all Nether Mobs, they cannot be hurt by fire or lava.

Tactics
Nether Dragons are easily provoked, remaining initially docile and follow the Player when in a 30-block radius. If the player or mob kills a Fire Creeper or Nether Creeper, any nearby Fire Skaidrons will turn hostile in a 100-block radius. They can shoot fireballs similar to a Ghast's and headbutt their target to deal huge damage (8 <3!).

An interesting feature about Nether Dragons is that they can enter any kind of portal (except Inckia), which means that if The Player can successfully lead a Nether Dragon and a Nether Creeper into The End and have a mob or boss there kill it, the Fire Skaidron(s) will be a big help to defeating the Ender Dragon, Ender Steve, Herobrine, Withers and Blue Thunder. They do not attack Skaidrons nor Nether Mobs.

Habitat
Lava Dragons or Nether Dragons are moslty found in Khuton and Nether.

Trivia
* If they can enter Inckia they will die, so that's why they cannot enter Inckia.
