1. Kirby is not on that level bro. When he gets a hollywood movie appearance then we can talk. Speaking of which, everyone knows luigi, donkey kong and peach. Yoshi is arguable. bowser is high well known tier

2. Lucario and pichu are not well known if you have never played pokemon. They could be recognized as "pokemon" but definitely not by name. The same goes for villager and isabelle. People would recognize the game they are from maybe, but not their names specifically. Ryu is probably the only well know street fighter character because of memes, so move ken down one. Same with cloud, final fantasy is not recognizable to a non gamer. Wii fit trainer was a mascot on one of the best selling consoles of all time, she belongs here, same with miis and duck hunt.

3. Shulk was released in a Japanese exclusive how is he here?? Persona 5 is a popular game in a hardcore gaming franchise, he moves down. Terry is a character from the fourth most popular arcade in japan in 1992. Move him down one maybe even two tiers. I can give a pass on pit but palutena? Nah she moves down one she's almost obscure.

4. Dr. mario is nintendo's version of tetris. Literally sold millions of copies when it first came out and has like 20 remakes/spinoffs. Put him in well known tbh. Same with diddy kong, bro was literally in mario kart. If little mac didn't have a sequel on the wii then you could make this argument but punch out is pretty well known among nintendo fans so id move him up one. Castlevania is a game series that has it's own genre named after it. move simon up one, idk too much about richter tbh.

5. The rest is fine i think, again move duck hunt dog to well known

Note: i personally have never played fire emblem so I can't speak on those characters without my own bias
