Then maybe Jigglypuff can be notable? This notability thing is hard Bulbasaur and Meta Knight being examples of what not to cover. Bulbasaur is the very first Pokémon in the national Pokédex and one of the three Kanto starters, and is a very nostalgic Pokémon. And it is what our affiliate Bulbapedia named themselves after. Meta Knight is popular in Brawl, and is on top of the competitive tier list. Well, the tier list is not that important as people deny the existance of tiers and it is based on popular opinion. However, the Kanto starters Bulbasaur, Charmander and Squirtle were very popular. And their final evolved forms Venusaur, Charizard and Blastoise have appeared on boxarts for Green/LeafGreen, Red/FireRed and Blue respectively as the only characters on the boxart. The legendary Pokémon Ho-Oh, Lugia, Suicune, Groudon, Kyogre, Rayquaza, Dialga, Palkia, Giratina, Reshiram, Zekrom, Kyurem, Xerneas and Yvetal are on the boxarts of Gold/HeartGold, Silver/SoulSilver, Crystal, Ruby, Sapphire, Emerald, Diamond, Pearl, Platinum, Black, White, Black2/White2, X and Y respectively. These Pokémon on the main games' boxarts are called version
mascots. And there are famous characters from the Mario series such as Mario (who we already have a page on), Luigi, Princess Peach, Bowser, Donkey Kong, Wario, Yoshi, Toad, Goomba, Bullet Bill. And we have Captain Falcon to thank for the Falcon Punch meme. And a lot of company wikis on Wikia including Wikia's version of
Nintendo Wiki have character articles. And Super Mario Wiki has full coverage on Donkey Kong and Super Smash Bros. despite the existance of Donkey Kong Wiki and Smash Wiki in the NIWA. The characters are a major part of Nintendo. Don't see why we can't just cover all of them. We have game pages even though the appropriate wikis have them too.
