Scrag was a member of Bebop and Rocksteady's Gang. He appeared in the 1987 TV series, Teenage Mutant Ninja Turtles Adventures, and Turtles Forever. His name comes from a coloring book. He appears in Turtle Tracks and Enter the Shredder.
He also has a Cameo in Turtles Forever and he is a mutant bat in Hot Rodding Teenagers from Dimension X and Shredder & Splintered. Also he appears in the Archie Comics "Heroes in a Half-Shell" mini-series.
It is unknown what happened to him after Shredder & Splintered, but it was shown that Scrag was briefly turned back into a human, when Shredder was on the TV Talking to the Turtles and Splinter and showed them what will happen if a mutant is hit by his Retromutagen Ray Generator. But he is seen as a bat again later when he is in a cage with the other mutants.
Though he would be seen as a human again in Turtles Forever when the Turtles arrive in the dimension where the 80's Turtles reside and is seen on the streets with the Yellow Mowhawk Punk.
- Scrag is the only mutant member of Bebop and Rocksteady's gang other than Bebop and Rocksteady themselves to appear in the Archie Comics series in his mutant form.
- As a noun, the word "scrag" means a person with a thin appearance. As a verb, it means to beat someone up. Both definitions fit Scrag as he is very skinny and is a punk.
- His mutant form resembles Wingnut's Archie comics counterpart minus the wings.
