Amphiptere (boss mob idea)

Okay so I am going to suggest this boss idea because I would like to see more fantasy type creatures in the game and a new boss. I would have it that when you defeat the ender dragon and get the dragon head, you can place it on the beacon and it's head's eyes would glow purple with the beacon letting out a light purplish beam of light. In the end would appear a large tower that would be a bit far from the end city. The top of the tower would be an alter where you awaken the boss with eyes of ender and a beacon.

This creature would have the same amount of health as the wither and would do twice the damage of the ender dragon with it's attacks. Its attacks would be biting players, charging at players and destroying any blocks it hits with it's charge, shooting projectiles at the player that explode, leaving lingering poison effect and destroys blocks that makes contact with the projectiles. The creature also heals a small faction of damage when it attacks players with it's bite.

If you are able to defeat this creature, it will fall to the ground and explode, letting out a large area of lingering poison III effect for a few seconds while it's look appears on the ground with a large amount of xp. The items dropped would be some scales and the heart of the Amphiptere. The heart and scales could be used for crafting along with the scales and some eyes of ender to craft a device similar to a beacon or conduit that grant new effects when in the end.
