メタナイト
is the greatest warrior in the galaxy and the nemesis of Meta Knight. His first appearance is in "Kirby Super Star Ultra", as the final boss of "Meta Knightmare Ultra". He performs unusual attacks with his sword, consisting of swipes, tornadoes, and energy blasts. He appears when Meta Knight, done with his training, wishes to the reformed Nova to fight the strongest warrior in the galaxy. Nova grants this by allowing a challenge with Galacta Knight, who is said by Nova to have been sealed away in ancient times for fear that his power was too great. He has a white mask with a plus sign on it and a hot pink body. His eyes are red and glow just like Meta Knight's, except Galacta Knight's eyes are more rectangular. He wields a purple lance with a white shield that has a purple cross on the front. As for his wings, they are angel-like and glow white. He must also be faced in "The True Arena", in which he is one of the Final Four and is fought as the penultimate boss.
