Thinks 'spiritual growth' occurs by sending a sleepy kid into a dream world, with no weapons, and a lot of insta-kill robots. Four times.
Gives the child a robot that may not fully grasp emotional nuance, but does grasp insults, and will use them if he fucks up enough.
Threw off her godly power to kick the shit out of a dude, somehow got the godly power back, and then proceeded to do close to nothing until prompted by fighting.
Complete radio silence while her descendant was desperately praying to her, only to unleash a massive wave of power when her descendant decides to fight off a great evil, alone.
Only spoke to said descendant once, where she was impossible to understand, and left her with a terrible sense of unease.
Horrifically direct; there are riddles and poems about things she may want, but Hylia herself will outright tell you. A spirit of power? No, fuck off, it's a red dragon and it's name is Dinraal. Give me the scale.
Robots. Seems to like robots. At least, if the shiny material that looks like her plumes is any indication, she had something to do with building a lot of tech stuff.
Weirdly associated with fairies; Zelda can't tell if she's a fairy or a god, she's associated with power-ups and hidden areas in BOTW, the fairy fountain theme plays when skyloft falls in SS, Fi being based off the fairy queen...
Basically Hylia is ridiculous and I love her very much
Nintendo please let me fight her as a bonus boss
