An artist named Bleedman, real name Vinson Ngo, has created, alongside a Powerpuff Girls webcomic, an ongoing comic known as Grim Tales From Down Below.
It was to be based off of the Grim Adventures, but quickly spiralled into a rough mix of fandoms with no clear goal as to what the story is truly about.
The series stars Billy, Mandy and Grim, but two characters that are not truly of Bleedman's own creation, but another's. These two characters are named Mini-Mandy and Grim Jr., and are the children of Mandy and Grim.
This webcomic has received many, many negative reviews.
"As Grim Tales dragged on, from one accursed page to the next, I found myself far less forgiving this time around. Seriously…Spawn? Nightmare Before Christmas? Wherever this is from? Danny Phantom? Him from the Powerpuff Girls? Joe Black? Seriously, Joe Black? Does anyone even remember that movie?" [Grim Tales References 1]
Despite outrageous controversy, such as Bleedman's comic panel on Mandy causing 9/11[Grim Tales References 2], or the panel on her committing suicide[Grim Tales References 3], many people continue to love and appreciate this comic.
It is currently unknown if the comic will remain updated, or abandoned, as Bleedman has not set clear goals as to what he wants for Grim Tales From Down Below.
