I bestow upon you the honor of stupidity
It might actually be Kirby's return to dreamland on the Wii, it was my first Kirby game ever and I kinda enjoyed it more than Kirby star allies.
Well recent lore implies that Galacta Knight was one of the four ancient Heroes of Yore who sealed away the Jamba Heart long before the events of Star Allies. He's also an interdimensional time traveler, so even though none of his battles are actually canon, Galacta Knight probably remembers it all. It would also explain why Galacta Knight's starting animation in Planet Robobot's True Arena seems to reference his defeat animation in Meta Knightmare Returns--despite the sub-games occuring in two distinct timelines, Galacta remembers them both because he is not bound by this thing called "canon".What's weird is that he's so... iconic (?), but he's never been in the actual storyline of a main game.
