Pre-Calamity:
Link: I am a very quiet, reserved individual. I'm very skilled with a sword, incredibly well-mannered and respectful.
Zelda: I am an eloquent princess who is regal and authorative, despite it not being the true me. Even when I am allowed to let loose a little, I'm still a little distant and contained.
Post-Upheaval:
Link: I'm a 100+ year old cryptid with Tony Hawk syndrome who has stabbed not one but TWO world ending calamities in the face. My hair has not been brushed in a hundred years, I eat stuff off the ground, my arm glows sometimes, and I run around bare-ass naked for the hell of it. I'll kill Ganondorf with a stick. I will.
Zelda: I am a 20,000+ year old cryptid and at this point being the goddess reincarnate is the least weird thing about me. I made Link eat a live frog once and I probably have eaten many more, for science. I probably cut my hair with a bokoblin fang. I do my homework at the bottom of a well like a goblin. I ate a rock once. I also willingly stabbed myself in the head with a sword. Ganondorf made a puppet of me that appeared and disappeared randomly saying ominous shit all over Hyrule and nobody questioned it because I'm apparently Just Like That Sometimes. I introduced ancient hylians to the iphone. I will turn myself into a worm. Don't even test me I will turn myself into a worm right now.
