Scraggy is a small bipedal, lizard-like Pokémon. Its body is mainly yellow in color, with a red scaly belly; below the yellow portion of its head, its body is cream-colored. It has large, bulgy ovular eyes with black pupils that are set to the sides of its head. Its white teeth appear to be constantly exposed, giving it a grinning appearance. It has two tiny nostrils above its grinning mouth. There is a small red scale atop its yellow head. Scraggy has loose, yellow shed skin around its legs, resembling baggy trousers. Some of the loose skin around its legs to trails off to form or cover its tail. Scraggy’s shed skin “pants” are very elastic and can be pulled up to its neck, which enables it to reduce the damage it takes from attacks.
Scraggy's pants-like skin looks similar to the PokéManiac's pants from FireRed and LeafGreen.
Scraggy is based on a lizard that is shedding its skin. Its Dark and Fighting typing and its appearance also draw imagery to stereotypes of youth delinquency and various related subcultures, particularly to music fan scenes such as punk and rap; being a lizard also ties into this aspect, as lizards grew in popularity as pets in the 1990s for being "off norm" and were further popularized by the lifestyles of celebrities owning exotic pets, especially by their ownership and care under Guns N' Roses lead guitarist Saul "Slash" Hudson.
Scraggy's English name may be based on the actual word "scraggy" which means thin/scrawny. It may also be a combination of the words "scruffy" (a way to describe someone's untidiness), "scrappy", and "baggy" (to describe its "pants").
