Add a new mob: The Voidshrieker

I was playing Minecraft, and then I think, "If cows, pigs, zombies,skeletons, chickens, and even spiders have different variants, then why the enderman does not have any variant"? Like a new type of Enderman, or a mob from Minecraft Dungeons DLC, but no! We only have the boring Enderman. That's why I propose the new End mob: Voidshrieker. An eagle-like mob able to spawn in the lonely islands that surround the main End island. His sound is like a very loud screech. It is able to catch you and transport you to the closer small End Island. His texture is like a human-sized eagle color purple with green eyes. I know is not a variant of an Enderman, but I really want a new mob in the End. Enderman's variants, I hope are added by Mojang, but please, consider this mob.
