I made this in Stickmin Creator. I am pretty proud of it.

Here are the main sprites so far

I finished the Battle Sprites

Overworld Sprites

Parchment Sprite 1

Note: This is not an official sprite. This is meant only to show the character's design.

Extraordinary Sans

Another Sprite. This time Luigi(Toriel).

Her AU name is officially Murder!Red. Also, here's the sprite sheet.

I finally finished Purgatory's overworld sprites

I got the main sprites for Sans done
