I made Endermen to look more alien-like as it is supposed to be. Endermen came from the world of The End, where there is no sign of the existence of earth-like creatures. This makes Endermen to be more suitable for the alien theme.

I gave the adjective Psionic as Endermen posses the ability to teleport from which it inherits from its mental ability.

Note: I tried to use this on MC 1.15, but unfortunately the old Endermen eyes are still rendered by the game. I have no idea why, but it sucks that it does not show the way I want it to be.
