Ultra Demon is the most powerful and Ultimate transformation that Alpha Demon has ever exceeded, whenever he turns Ultra, his speed, strength, endurance, and stamina increase to 100% making unbeatable to take down. Although in this form he is so powerful, that he has no need for weapons and just prefers to fight with his bare fists though should he need a little extra firepower, he has three Abilities he can use at will.
1.Ultra Demon is able to summon energy bombs from his hands which are called MAGNUM BOMBS and is able to use them against nearby or far away opponents.
2.When in Ultra form, he is able to summon MIRROR MANIPULATION which allows him to manipulate his body into Mirror like constructs with the help of the Mirror chains at his disposal.
3.DRAGON'S FLIGHT is his final ability which allows him to soar into the air and attack enemies from above
Although Ultra Demon is powerful, it takes a lot of energy out of Alpha Demon, and eventually he has to power down, but that's why he prefers to finish off his opponents as Ultra Demon as quick as possible
