Sylvia is voiced by Yanni Aimee! Sylvia wears very earthy brown colours with green/teal as highlights. Her beanie is a forest green with cat ears. Her eyes are teal, and her hair is brown with green accents and kind of resembles a pine tree. Her brown sweater has a neck thing idk what its called. She wears a similarly foresty-dull green coloured cargo pants. Her main partner "Mythian" is a green cyborg bear called Botacub.

Olli is voiced by Raine O'Brien! They wear very blue and dull tones, that matches their personality as being really down-to-earth and chill, and not really having a preference on many things. His hair is poofy and is growing out towards the neck. They wear glasses, a blue jacket, and black sweatpants. Olli feels like he can never grow out of his father's shadow, as his father created the "Mythologica", a device resembling a phone that can be used as a log for Mythian studies. Olli is very often seen with their own Mythologica, watching entertainment (seen in the image, the device with the red casing). Olli isn't as linked to his "element" as Sylvia or Mico, but they still ended up with the Water type Mythian called Pescapod as their first partner.
