Morpho Knight

Morpho Knight is the reborn form of both Galacta Knight and the Butterfly seen in all the main Kirby platformers since Kirby's Return to Dream Land. He is said to have formed when ”the greatest warrior in the galaxy“, a being twisted by his dark past, came in contact with the symbol of purity. He is the final Boss of the "Guest Star ???? Star Allies Go!" mode.

Battle
Like the other knight, Morpho Knight is able to use his sword to block attacks. He is also able to teleport. In his second phase, he summons two flamming sword that can be enlarged to cover a lot of the screen. Morpho Knight also has the ability to emit a soundwave that will take control of the Allies.
