Pixel is a Fairy/Rock type because fairies are secretly in every single rock we find when the sun goes down. Don't question my logic, fairies are in rocks.
MayhemMcKoi is a dark/water type because in her icon she's hold a water type and dark type because 'Mayhem' and i'm an Umbreon
I'd say @Lillie is a Dark/Fairy type. Even though she can be a little edgy at times, she's a pure little cinnamon roll
Hrae would be Dragon/Water because he is a little dragon and his rank color is the same color as the water
