Ender Brute.

After being in a few Piglin Bastions and almost dying many times to their Dimension Piglin brute and seeing how empty the End is already, I Believe that the Ender Brute would be similar to its worldly neighbor besides the Overworld.

If you find a Ender Brute they will at First Teleport in-front of you and could Easily hit the player even being under a safe 2 block tall shelter.

They Will Spawn in their own style Structure and would deal 10 Hearts of Damage. Being more stronger and Faster than a Normal Enderman.
