Galacta Knight (Galactic Knight in the Japanese version) owns the title of the greatest warrior in the galaxy. He appears in Kirby Super Star Ultra in the sub-game Meta Knightmare Ultra and The True Arena and in Kirby's Return to Dream Land, also in The True Arena.
He first appears as the final boss of Meta Knightmare Ultra. Meta Knight wished to fight him in order to become the greatest warrior of Gamble Galaxy. With NOVA's help, he fought him and won the battle. Later, though, Galacta Knight makes a comeback as one of the Final Four in The True Arena.
He later makes a reappearence as one of the bosses in The True Arena. In the Kirby Master movie, he is seen cheering Kirby on.
