Sidon

I adore his positivity and enthusiasm, and how open he is about his feelings. He doesn't hide them with snarkiness or anything, he just says what he feels. It was a breath of fresh air when I played BotW, as was him actually helping in several ways during the Vah Ruta questline, instead of going "Hey can you risk your life for us? Ok cool thanks good luck, I'll just be waiting over here."

I also like how he does have his insecurities, however, growing up in the shadow of his sister, who was practically sainted by his people, and still struggling with her death himself. I like that TotK built on that in his quest and has him acknowledge his feelings of guilt and put his trust in others again rather than believing he should protect everyone by himself.

I love his design too, especially in TotK, because the crown and collar are ever-so-slightly over the top which is pretty amusing to me.

Mipha

I like her kindness, she's a very sweet lady. But what I almost like more than that, is that her kindness does not equal her being meek or cowardly. She has real inner strength and a strong sense of responsibility and duty toward her people, which is what makes her put her life on the line.

Urbosa

Love me a beautiful warrior lady with a deep voice (and actual dang muscles). Aside from that, though, I love Urbosa's motherly bond with Zelda, and how she can be kind but also firm where needed.

Revali

At a basic level, it's fun to make fun of him and his pompous attitude, but he's also a genuinely interesting character to me.

There's just a lot to go into, and I'm doing my best to not turn this into an essay, but he is the only one out of the four Champions who wasn't born with a special ability. He developed a new technique, isolating himself from his people to master it, and he didn't even get to pass that technique on to anyone. He acts pompously, yes, but it's not entirely unwarranted, and can be read as him masking his insecurities.

Zelda (BotW/TotK)

She has just the absolute worst time of it in BotW and TotK, but despite it all she keeps going, and I love that. She had the weight of the world on her shoulders in BotW, and failed to prevent disaster. All her friends died, but even then she didn't give up. And in TotK, she did all this work and made an incredible sacrifice just for the possibility that it might help Link.

Also, her nerdiness when it comes to ancient cultures and tech is just plain adorable.

Link (Skyward Sword)

Honestly one of the best silent protagonists I've seen, and so far the only one of which I can genuinely say I love them as a character. BotW Link comes close, but SS Link is just a bit better.

My love of him is mostly due to just how expressive he is during cutscenes, which makes him come off as a sweet and slightly dorky young man. He actually seems emotionally affected by the story too, which is hard to say of a lot of other silent protagonists (*glares at DQXI's hero*). It's hard not to like him and root for him because of that.

Groose

I really didn't think I'd like him at first. I thought he'd be a generic bully character whose relevance would quickly vanish after the game's opening and Link sets off on his adventure. Yet, not only does he actually have a role to play in the story, he goes through some absolutely lovely character development which turned him into quite the endearing guy!
