Nintendo

Favorite character is Midna from Twilight Princess. Her design is just so weird but it works. She antagonistic towards the player but I can't help but love her. Your friendship grows throughout the game until that one incredible shot together. And the surprise ending is both fun and tragic.

EDIT: this shot.

Favorite relationship is Marin from Link's Awakening. She's wonderful on her own, but then she shares so much about her life on the island and her dreams and grows even deeper as a character. I feel a stronger bond between her and Link than any incarnation of Zelda.

Definitely Zelda. I mean he is the hero of every game and always tries his best to save the Princess whose name I have forgotten.

I like the guy that runs the squid/battleship mini game in Windwaker.

Sploooooosh!

Mario

Definitely Impa - especially in Ocarina of Time

The Groose is loose.

I relate to this lady

Ilia, The "It's dangerous to go alone, take this" guy, Error, The Happy Mask Salesman, Tetra, Skull Kid, Riju, Midna.

Purah took it over.

She's awesome. Loved her ability set in Hyrule Warriors already, and in Tears of the Kingdom she's the one you return to frequently enough, serving as the game's "anchor".

I personally like Zelda. She's kinda kept the franchise going after all this time ya know... and she's the only one that's in ALL of them. That link guy is just a side-character.

Tetra, Midna, and Ruto

WolfLink

Do bosses count? Because I'm gonna throw in Molgera and Volvagia because both of them are great fights with stellar music.

I did a 3-heart run of Ocarina a year or so ago on original hardware. I died almost 50 times in that run, and Volvagia and Morpha were at least 35 of them.

I also have a really soft spot for Medli.

Yeto! Twilight Princess.

Linkle and princess Zelda ^^

As a kid I was in love with Superman. But, when I first got a Nintendo, I got to be the hero.

That hero was Link.

So, my favorite then and still my favorite now. Link!

Zelda. She frequently surprises the player with how much of a badass she is.

In Wind waker she commands a gang of pirates many times her size. They respect and trust her and would follow her to the edge of the world. She also kills Gannon by bouncing an arrow off Link's shield. How badass is that? The hero doesn't even kill Ganon. Zelda does.

In Ocarina of Time, you spend all this time trying to save her after you saw her get kidnapped, only to find out she's the badass ninja who's helping YOU the whole time. She don't need no saving. She ain't no damsel in distress.

In BotW, you watch her struggle and struggle while she tries everything to unlock her power. Then in the face of certain death, she unlocks her power, and without hesitation, and without any training using her power, she fights Ganon for 100 years, holding him off to buy time while Link cooks food in his underwear.

In TotK, Zelda makes the ultimate sacrifice, trading her humanity to give Link back his trusty Master Sword so he can defeat Ganondorf. She also becomes immortal when doing this, so this is a massive sacrifice. She may never be reincarnated, as she's not dead. She has to live in that dragon body forever. It permanently altered her mind, too. She lost all her intelligence as part of the transformation. She's basically going to live in torture for eternity, but that was the sacrifice that she made without hesitation to give Link a chance to save Hyrule.

Link would rarely be able to save Hyrule without Zelda. They both have important roles to play each time.
