After 4 adventures, a lot of villains, and of course, A LOT of fighters and characters, everyone, including the ones from other universes, finallly reunite in what seems to be a fair battle against an unknown entity known as Galeem, who took control of Master Hand and Crazy Hand, sadly, 99% of our heroes (and villains) were defeated in battle, except for one, Kirby, it is their job to bring back their fellow fighters while also collecting multiple spirits on the way, with a lot of epic fights, animation, and more, this, is the final season.... (unless Sakurai makes a new game for the switch 2, who knows)
