This is an old sketch/doodle of Cherry and Sage. Cherry happens to be Sage’s bitty, and he is an absolute gremlin. Nothing is safe from him lol

He’s a Fell Type bitty. :3

Wanted to try my hand on some other sans' from different aus.
Personally, drawing horror and murder sans was fun.
Their eyes are so unique.

Comic of the OP’s Sona playing a video game with intensity, Underfell Sans teleports in without being noticed and startles the OP into throwing the controller at his skull

Edge and Dan dramatically leaning against Sci (OT3 pose reference by croxovergoddess @ Tumblr) Edge and Dan burns their chaotic energy while Sci holds a leash attached to keep them in check (Based and Inspired by Ship Dynamics Leash Meme) Saitou (human!Sci) being indecisive to pick either Daniel (human!Dance) or Edward (human!Edge) as his romance option. Saitou, Daniel and Edward with their trigger eyes and signature colours.

① Sci accepting Edge's proposal to dance with him. ② Dan(ce) teaching Sci to dance together with Edge. ③ Edge completely embarrassed of Sci taking the lead as they dance together.

Imagining this as their first encounter:

Edge is socially awkward and easily embarrassed by Sci's quirkiness as a curious scientist meeting another skeleton from another universe for the first time! :3c

A scifell pen sketch (shaded with coloured markers) of Sci leaning close to Edge without social awareness due to being enveloped by his fascinating to meet a skeleton from an alternate universe for the first time. On the other end, Edge is socially awkward and embarrassed of the nerd approaching him with close approximately. Slightly startled by Sci's approach as the skeleton scientist examines his facial appearance.
