How about a donkey kong anime. It could show how dysfunctional they are as a family. If done right it could act as a parody to all those sitcoms that are like that and be a fun watch. Though it might only appeal to the western audience.

Fire Emblem anime pls.

FE, Kid Icarus, Splatoon would be great for an anime. Zelda is fine too.

Mario is too different maybe because I've watched the Mario cartoons back then.

star fox has good characters that can bu built and revive the game franchise.

I'd like to see the Kid Icarus Anime, Zelda Anime, and a NEW Fire Emblem Anime. There was an old Fire Emblem Anime where "Marth" was called "Mars". It was decent enough.

Nintendo has so many IPs that would work so well as a T.V./Anime show, that it's so ridiculous. I think the ones that would work best would be Mother, Splatoon Pikmin, and Kid Icarus. Also they should bring back the Kirby and F-Zero animes as well.

Also I would like to see a live action, Game of Thrones style Zelda show. That would be amazing.

Metroid, Fire emblem and Kid Icarus would be my top picks

Kid Icarus would work really well. Star Fox could also work pretty well. Wonderful 101 could be amazing, but it would be hard to market. Fire Emblem would be a natural fit.

Professor Layton would be interesting. But is he Nintendo IP?

Smash Bros anime with an emphasis on jiggle physics
