I've been inactive for quite a while, though I lurked a bit in the meanwhile.
Anyway, it seems that some hours ago there was a discussion about Kirby newcomers with Adeleine involved somehow, and I wasn't here
I feel like any Kirby newcomer is unlikely right now, but part of me still hopes that the missing spirits of Adeleine and Ribbon mean something for DLCs.
She would have a gimmicky gameplay based on traps and ranged attacks similar to Villager, and her moveset would be full of references of popular enemies from the Kirby series.
Though, I think Sakurai is pushing for Marx... not in this game, maybe in the next one. He put him as a boss so he can get more popularity, and then...
I dunno, maybe it's just me.
He even gave him new moves with the same creepy factor as 0 and 0^2; insane eyes and those branches-things made of nerves or something; it seems like an attempt to give to Marx those traits that the Dark Matters are praised for.
This said, I recently started to play as Villager a bit more seriously (still Smash 4). I never played as him in the past, I never cared... though, some days ago, I decided to try him, to try to understand the timing and the strategies... well, I'm not a pro but I learned a lot. I love to trick the enemy into a growing tree XD Only played him against Lv9 CPUs at the moment though.... some are very easy to defeat, some others like Doctor Mario gave me a lot of problems.
Kirby may be weaker but it can easily adapt to almost any opponent (maybe Villager too, it's just that I'm not good enough with him yet).
