What do you think of each of the Champions?
All of them? That is quite the ask if you do mean all, but since you asked, then I shall give!
Revali is undoubtedly a Champion that is close to me, having been there thick and thin for me, during the Calamity and the fall of the Blights, most of the time himself and I just talk a lot of the time at his Flight Range, I don't think it is possible for me to dislike him for how much of a mentor he is, I've gotten so used to his rambles or his moments of smugness that last probably for hours to days, so you can imagine it is more than a good bond
Daruk is a Goron I always look to when it comes to a fighting spirit, I have seen him tank his own Boulder Breaker in a training session, which has only made me want to improve myself to become the best for the Rito, and for Hyrule, I just wish I could meet him half way, my feathers ache from the thought of travelling somewhere sweltering
Mipha means quite the lot to me, and that is despite myself being a Rito, when I first met her I could only feel that she was someone that a lot of people could love because of how kind hearted she is to keeping the peace, even when she had the encounter with the Lynel, I heard she did not ever relent, sometimes I cannot help but feel I need to owe her for her efforts, she's that important a figure!
Urbosa is the most boisterous of the Champions and by a Hebran mile, many times I was at her side or helping her deal with the Yiga there was always a sense of, mind my language, kick ass-ness, the fact that she learned to use her powers to the point where she never needs to snap her fingers, it shows me that dedication seems to be something she takes to heart, and then you have to factor in that she's been Zelda's caterer, and that alone has made me admire her
