Curate, connect, and discover
My headcanons for what each link would become when exposed to the shard of twilight/to the dark world and why.
Skyward sword Link (sky): straight up puppy. He's a very friendly, sociable, and loyal Link. Maybe more like a golden retriever
Minish cap Link (minish): Mouse! Very tiny mouse. I think he's generally pretty shy, cautious, so a small rodent would make a lot of sense.
Ocarina of Time/Majora's mask (time): Canon wolf.
ALTTP, Oracles, & Link's awakening (legend): Canon bunny
LoZ I and II (Hyrule): I don't really know em that much but I think dog, maybe even Retriever, like Sky. Mostly based off LU.
Twilight princess (twilight): canon wolf
Four swords adventures: Rats! Since they're very social, could split into a rat pack. Rats can have a very wide range of personalities, like most other pets, but I think they fit Shadow Link a bit more, so by default I go rat.
Wind waker & phantom hourglass(wind): Frog, because I want them to be able to handle both land and water.
Spirit tracks: I got no clue I never played that.
Hyrule warriors (warriors): cat. Very pretty, very opinionated. Will tell you if you're annoying them.
Age of Calamity (Champion, different from post-memory wipe Link): A dog. But now, a very specifically trained dog, like a German shepherd.
Breath of the wild & tears of the kingdom: They're a blupee. If you'd prefer a real animal, a mischievous little rat. But I prefer blupee because he is very much a little blue guy that runs around the forest
