I really really want to see Quetzal again. I really like the villagers based on different cultures and he's definitely my favorite. I hope he comes back someday.
I had to look them up since I didn’t play any of the older AC games long enough to become acquainted with any of the villagers (except NL). I’d like Meow and Kit ; I think Meow’s appearance is pretty unique looking and kit is really cute.
If they could return without needing amiibos, I’d like to see Epona and Felyne if those count. I bought the monster hunter cat’s amiibo with a gift card two years ago or more and it was about $30 so I don’t want to open it.
I’d love to see Champ. He was the monkey that resembled Porter. He only got removed in New Horizons, but I would love to see him return. I thought he was cool.
My Gamecube buddies, Hank & Emerald! I miss them both so much.
I'd also love to see Twirp and Kit return, and I'd absolutely have them on my island if they were still around. Chuck & Weldon would be welcome too. Ah, there's too many cut villagers that I really love, come to think of it.
Wolf Link is my favorite villager in any Animal Crossing game ever. I'd love to see him in New Horizons. I have a Link amiibo all ready to scan him in if they do add him. He was in my New Leaf town for years, and I miss him.
I have not played any other games so I am not super familiar with the other villagers. I’d welcome any of them back into the game, the more the merrier.
I would particularly like Aziz the lion and Poko to come back. Aziz because I read an old character card for Genji listed that Aziz was his best friend, which is adorable, and Poko because he is Ike’s son. Ike is my favorite cranky and it would be so cute to be able to have both of them.
honestly i think there are a decent amount of cute cut characters that never even made it past the gamecube game (would also love felyne from new leaf tbh)
my personal favorites are:
the last one (petunia) would be so cute with merengue and chai
