In the end cities there should be a mob with a powerful ender screech sound: THE ENDER GHAST!!
The ender ghast travels slower than a regular ghast and teleports if you use a bow and arrow, the ender ghast shoots the dragon breath ball and you cannot swipe the ball back to him.
The ender ghast will call to other ender ghasts near them to group up and attack the player, the only way to stop it is to kill it with a melee weapon.
If enderman also hear the ender screech calling for more ender ghasts, they will also attack the player.
