Nightmare

Nightmare Pain Stevenson (悪夢の痛みスティーブンソン in Japanese) (Also known as Squirrel) is a main character in Awesomia.

Original creation
Originally created by Australian deviantart user KineticSquirrel (real name Adam) (known at the time as Squirrel245) in 2008, Nightmare was originally supposed to be more sadistic, and his 1st true form appearance was in the photo "Santa Hat 2". In 2015, Adam moved on to other stuff besides South Park and forgot he made the character.

Nduru D. era
Nduru D. in 2020 found the character and instantly loved how he acted, so he tried multiple ways to use him as "fanon fanon" (term he coined for "fanon of an OC or fan creation"). But that did not work, and so he decided, "Hmmm.... should I still use Koopatroopaman.... I want it to be like Di- aha! Nightmare and Koopatroopaman!". It was originally called "The Nightmare and Koopatroopaman Super Funny Cartoon Show" until 2021, when Nduru shortened the name to Nightmare and Koopatroopaman. Nduru thankfully dropped the Idea of Nightmare being brought back again. Since he is abandoned by KineticSquirrel, Nduru kills him off with humorous and weird ways in every episode.

Appearance in Awesomia
In Awesomia he dies a lot.
