Arnold the Third

Arnold the Third (nicknamed Arnie) is a shadow creature who, along with Gary, captured Luna in Elemental #2. Both were sentenced to eternal suffering as a punishment for capturing the wrong person. However, according to fans, Gary was rescued by the Gary Protection Squad (GPS), and Arnold the Third actually entered eternal suffering.

The character is unnamed in the comics, but creator ScratchStang canonically named him in the Scratch comments.
