Mobs

Evocation fang, Warden, Elder Guardian, Zoglin

The Evocation fang is a mob spawned by Evokers. They only stay up for a short time. They are also hostile which means they attack players. This mob does a lot of damage but has no loot. They spawn in two circles if a player is close by, or in a straight line.

The Warden is a big mob that is soon to be added to Minecraft. The Warden is the first blind mob in the game. The Warden will get faster when attacked. In Normal Mode it can kill a player in fully armed in Netherite armor in 2 hits.

The Elder Guardian is a stronger form of the Guardian and is found in Monuments underwater. They will drop a sponge when killed. They also shoot lasers to attack players. The Elder Guardian is also a miniboss. 

If a Hoglin stays in the Overworld or the End it will start to zombify. Zoglins are undead mobs that will attack every mob except the Creeper and Charged Creeper in Java Edition. In Bedrock Edition will do the same thing in Java Edition except they are passive towards players.
