Galacta Knight is a reoccurring boss from the Kirby series, acting as a rival to Meta Knight. He is often referred to as the Greatest Warrior in the Galaxy, most notably in his theme, and was sealed away by the ancients because of his great power. Galacta Knight first debuted in the Nintendo DS remake of the popular Super Nintendo Entertainment System title Kirby Super Star Ultra, where he served as the final boss of the Meta Knightmare Ultra sub-game after Meta Knight summoned him. He also appears as a boss in The True Arena.
Galacta Knight has a similar fighting style to Meta Knight, although he has a few energy moves to his arsenal such as Crescent Shots, Flame Spine and Revolution Sword. Galacta Knight can even rip open a hole in the fabric of space and time to fire a large laser.
