Mad Melter

The Mad Melter was the disguise of Mr. Thawker and his sister, Melanie.

Personality
Not much is known. It's only really ever shown to have its arms up and mouth open, in a menacing stance, even during chases.

Powers and abilities
The Mad Melter had the ability to easily melt snow and was claimed to also be capable of melting people, although the latter may have been false as the statement came from Melanie, one of the culprits.

Scooby-Doo! Mystery Adventures
After having melted the snow at Fun Mountain Ski Lodge, driving the majority of its guests away, the Mad Melter attacked Mystery Inc. when they arrived there for a stay. First chasing Shaggy and Scooby-Doo down a mountain, through the woods, it later attacked Daphne, Fred and Velma after they had investigated the neighboring ski lodge, Pine Star. As it chased them, Shaggy and Scooby dumped a snow cone making machine in its path, knocking it to the ground. While it is unknown if it was Melanie or her brother Mr. Thawker under the mask, it is revealed that they were both responsible for the creature, in an attempt to drive all the business in the area to their ski lodge.
