Kremor/Kremors (Hostile Mob for the Nether)

This is an idea for a new original type of hostile mob. This would be a mob that spawns in the Nether. It would be a little taller than you. They would be reddish orange, and have 2 heads with yellow eyes. They would also have four arms. They will spawn around the more open biomes of the Nether. They would have 70 health and have almost the same knock back resistance as the ravager. They will either charge at you knocking you back 4-6 blocks, or they will leap up and create a fire wave explosion when they slam on the ground, if you get hit by this you will burn on fire. You can jump to avoid the explosion, move away, or you can use the fire resistance effect to avoid getting burned. If you kill them they could possibly have some special drops that could be beneficial for progression in the game. I think this mob would add more challenge and variety to the nether and Minecraft in general, and I hope to see something like this at some point.
