Ender Ray : a passive rideable flying mob for end travels.

As we have the strider as a passive in the nether to cross lava seas that are the main natural danger there, I suggest also a similar mob for the End to travel above the void that is the End natural main danger.

Let me present you my idea : the Ender Ray.

A flying passive mob sometime encounterable in the end, flying in the air. Chorus fruits could be used to breed and ride them. To ride them, we need at first to attract them with chorus fruits, then use a saddle, and we control them with a chorus fruit on a stick. The ray would head in the direction the player is looking, allowing players to fly above the void or move vertically and the ray would speed up if the player clicks with the stick. The ray would drop leather or membranes at death, I don't have any ideas about possible loots, but it's not the main use for this mob.

About appearance, It would be the living version of the phantom and would look like the mob B voted from the 2017 Minecon, with purple eyees to give it the appearance of a creature from the End like endermens and the enderdragon. 

Like piglins and hoglins which can only live in the nether, the ender ray can only live in the end. If it leave the end, it will mutate, rot and become undead (a phantom). It could become a red phantom if it's in the nether, a kind of easter egg about a red colour thought for the phantom that have been scrapped because it looked like a Nether mob.
