Ugh, not another psychic. And one who looks almost exactly like Ness?
If MOTHER is going to be represented once more, I'd much rather prefer Jeff or Porky. Jeff at least used gadgets and doodads, and Porky can bring something fresh to the roster in the form of a mecha.
It'd be the closest thing we'd get to a playable Eggman or Wily.
Technically the most interessting Mother character by far would be Lucas's twin brother.
Porky would be cool to though indeed.
Let's just say I wouldn't mind Ninten, if only cause he's a Mother character.
StarFox trio? Even if they are semi-clones, I got no problem with it.
Two other 'trio' concepts:
Blue Haired Sword Lords: Marth, Ike, Chrom
-Pretty much confirmed to happen. Chrom will most likely share similarities with Marth due to also weilding the Falchion. And most could see similarities to Ike to, due to having Aether.
The big ape and two monkeys called Kong: Donkey Kong, Diddy Kong, Dixie Kong
-Even if Dixie doesn't make the roster innitially, she's a very likely DLC candidate. Will most likely have a similar sort of moveset to Diddy, and even if she doesn't, characteristic as build, weight and movement will create similarities. She could potentiall even carry around people with her hair, ala DK! Spinning Kong? I can only think of ONE Kong that can fly by spinning.. And it isn't DK.
So Ninten? No problem.
But I still would prefer Claus as a semi-clone.
