What's everyone's gender and orientation?
This one I can answer more easily~
Dragon Peppino: male, uses he/him, asexual/aromantic
Technically all the Great Dragons are genderless and choose how they wish to present and be identified by each other. An interesting piece of lore is that they are molded as "blank slates" with the exception of being given a name and element to wield. They don't even require nutrition and when first born, they do not even have a digestive tract. Can't go into further detail, because that will be spoilers :3
Vigi/Veeg: male, uses he/him, asexual/demiromantic (had a wife, but probably won't become involved with anyone again)
Jelly slimes do not have reproductive organs, so they also are all technically genderless. They reproduce by splitting, like cells. Vigi and Peppino are family and about as close a platonic pair as you can get^^
Goo-seppe: nonbinary, uses he/they, asexual/aromantic
As a clay golem, Goos has absolutely no sexual or romantic desire in him. He is also a clone of Peppino, so those traits have somewhat carried over from him, but they are also their own person, and just... don't feel any of that. He forms very close friendships and his nature as a guardian causes Goo-seppe to be very, very protective of anyone they form bonds with.
Lucky Rabbit Noisette: female, uses she/her, asexual/heteroromantic*
Kobold Noise: male, uses he/him, asexual/heteroromantic*
(I don't know all these terms...) Noisette and Noise are only for each other, they do not/will not fall in love with anyone else. Honestly, all of this cast is asexual.
The Noisecouple have hearts for no one but each other; they are beautifully in love and dedicated to each other's happiness. They are not capable of having kids together, but that isn't even on their minds. Even when separated, they think of their partner.
Lil' Pepperman and the Toppins: LP is male, uses he/him*, asexual/aromantic
When being referred to, Lil' Pepperman's pronouns are he/him, but when he speaks, he often uses us/we, because he speaks for the Toppins as well. This family almost thinks of themselves as a collective; LP is just the head of the group. All of the Toppins use it/its.
As for orientation, LP is aroace of course, but the Toppins are all different! You can check here for a more in-depth description! Tomato and Sausage are romantic partners, Pineapple is aroace, and Cheese and Mushroom are platonic partners~
Devil's Food Cake: genderfluid (usually male), uses he/him (unless otherwise stated), asexual/most likely aromantic, but who tf knows
Who can guess what's in the mind of the King of the Fae? He can shapeshift and often acts like a tease, but is there anything behind it? He would never give a straight answer.
