Endraptor - Hostile Ender Mob

Endraptors would either look like a giant hawk or small-midsized (Dinosaur)raptor(with black/purple and maybe grey skin, obviously). Regardless, they would spawn in End highlands. Endraptors would attack the player and possible also Enderman. They would either be carnivores or omnivores.

If they would be omnivores, you would feed them chorus fruit and tame them.
In the other scenario, maybe you could feed them some rare meat from overworld?
They would not attack you if you are crouching with said meat/fruit. Alternativly, you just can't tame them.

I think end would really need more creatures, and theres never too many pets. Raptors would also help immersing yourself into this biome and dinosaur fans would certainly be happy(in dino raptor version).
