- “I am some random character created by smg4!”
Doopliss is some random character created by SuperMarioGlitchy4 who is a darker version of Paper Mario. He appeared two times: first was in the blooper WEEGEE Disease, the second was in Hunt for the Hero's Clothes. Both times he stole something for no apparent reason. The first time Mario met him he defeated him, however the second time Mario shot and killed him, which might explain why he hasn't appeared in later videos.
- His sprite is actually the unused angry Mario sprite from using the beta Angry Power badge in Paper Mario's files.
- His name is shared with the boss character in Paper Mario: The Thousand Year Door.
