I have a character that I will show another time.

Dandy, Astro, Goob and Boxten belong to Qwel (I think that's his name)

Sonic belongs to Sega

Thomas Gotze and Project G-1 are from the video by Thomas and his friends Paul's Vids. The designs I used are from Meet-The-Little-Demon, credits to Paul's Vids and Meet-The-Little-Demon.
