You know what would have been hilarious?

If Metaknight had made his wish to fight the strongest warrior or whatever, so Nova just summoned Kirby.

..."I ould have avoided all of this, couldn't I have?"

In addition to the "dragon ball" parallels in Metaknightmare Ultra, I think it's interesting to note that Kirby, who is motivated entirely by food and fun, has a circle of friends that consists almost entirely of people who have tried to kill him and is consistently the strongest despite everyone's best efforts.

Kirby is Goku. That makes Dedede Piccolo, Metaknigh Vegeta... And screw it, Bandana Waddledee can be Yamcha. The timeline doesn't work out so well, but...
