Some TMNT stuff really isn't for little kids.
In the IDW continuity, Scrag first appears in Teenage Mutant Ninja Turtles issue #105, as a patron of the heavy metal nightclub named Kennel Klub. He was seen in the background alongside Grunt, Dumbo and Dopey when Bandit and Puggle confronted Jennika.
As a mutant, Scrag is a humanoid bat with gray fur and two large bat ears. He has two hoop piercings on his right ear and wears visor sunglasses even at night time. He wears a black leather jacket, with a slightly torn white shirt underneath.
- Scrag's human form was seen playing the guitar at a street concert in the Teenage Mutant Ninja Turtles 30th Anniversary Special alongside Bebop, Rocksteady, and Grunt's human form.
