Unisus

History
A Unisus is a combination of a Unicorn and Pegasus. They were specially bred by Notch during The First Creeper Invasion, to help him take down Herobrine's army. They were first used to fly to villages,that had just been attacked, to heal people. They were used by The Mojang Army to assault Herobrine's air ship. Before the ship crashed into a mountain, Notch and his surviving men flew away on there remaining Unisi. Since most of them were slaughtered by Zombie Pigmen and CR33P3RS, Mojang realised they weren't made for battle, and just put them in Hospitals to heal people.

Tactics
When fighting during The First Creeper Invasion, they would attack by impaling enemies with their horns. Another way of attack they used is to shoot a healing beam at Herobrine's Zombie Pigmen. Since they were undead, they died immediately.

Abilities
Unisi can fly using their beautiful wings. When hurt, they can shoot a beam of light out of their horn at themselves, automatically bringing them to full health. Sometimes, if they're close to death, they'll make what is called a "Piercing Neigh", which will summon more Unisi to help him or her.

Taming
A player can tame a Unius with an Enchanted Golden Apple, and a Jungle Sapling. One of the advantages of having a pet Unisus is that if you press shift and right click on it, you will be restored to full health. Another advantage is that they will kill any hostile mob in a certain radius of you.

Trivia
When bitten by a Decaying Zombie Pigman, they will turn into a Batwing.
