Few denied the quality of Kirby's Epic Yarn, but it wasn't a Kirby game. It was a cute little experiment in a different art sty- Wha- WHAT!? KIRBY WII IS BACK AND BETTER THAN EVER! ...What's that? Final Smash-like moves with the copy abilities? YEEEEEEEEEEEEEEEE- *explodes from awesome*
What's that? They all have specific powers you can't change? Ho hum... wait, you can choose to play as the other colored Kirbys from Amazing Mirror and each have your own power?! AWESOME!
Kirby: Planet Robobot looks nice and I like that it's similar to Triple Deluxe, so this should... is Kirby riding a robot? Can that robot get copy abilities?!? Goodbye all of my money! Oh, and as a bonus not only are there new abilities there's also a new amiibo line with the Kirby amiibo giving you the UFO ability, as well as the return of Meta Knight in playable form.
There's also a special four player mode that has RPG elements.
It also looks like several mini-bosses from Kirby's Return to Dreamland make their return after being absent from the 3DS version, including mechanized versions of Bonkers, Kibble Blade, and King Doo. Also, Dubior returns, but it was a robot anyways, so it's not affected. Sphere Doomers even return as well in the form of holograms.
DARK MATTER, SECTONIA, AND GALACTA KNIGHT return as the final bosses of Meta Knight's mode, and if you really want to get technical, NOVA from Kirby Super Star returns as well as the true final boss.
