Powers and abilities
Hebediah Grim's main weapon of choice was a large mallet, which he would use to smash objects and try to hurt girls and boys with. A crack of thunder would always accompany each strike of the mallet, and the sky would turn red whenever Hebedia was attacking.
Scooby-Doo! Mystery Incorporated
Gary and Ethan disguised as Hebediah Grim targeted and attacked girls they found attractive while claiming they were indecent an impure (Though Velma found it annoying when the judge bluntly told her she was safe since she was 'decent' and 'an example of purity', when in fact it was just because neither Gary or Ethan found her attractive). This was becaused they wanted to impress girls by having one of them saving them when the monster was attacking. After that, they would be recognized as heros by the girls and eventually they would make up with each girl.
