I did some references for Wilbur, Techno, and Phil in the Space Bois Inc au! This is close to how I picture them looking like.
Also all of this info is stuff that I’ve already said, just paired with pictures now!
Wilbur is very lanky and tall. He has four arms and the spots on his face glow a soft blue color. The cloak around him is actually extra skin that is tougher than the rest of him. When he isn’t using it, it lays loosly on his back. He also has the ability to divide his pupils and focus on two things at once.
Techno is basically a piglin but with a little twist. He is broad shouldered and fairly large. His skin is tough and hard to pierce and his nails are strong like hooves. He produces a healing liquid in his mouth and if he doesn’t empty it, it overflows and drools out of his mouth. His skin and blood both run hot, too hot for a lot of species to handle.
Phil is a mix between a bird and a sentient plant. He has a ruffle of feathers around his neck and that cover half his face. He doesn’t have a mouth but is able to speak telepathically. Vines and flowers wrap around his body and he is fully able to control and grow/shrink them at will. Despite the amount of plants attached to his wings, he can still fly. His lower half resembles a bird and his hat is actually just a giant flower.
