The Golem was the disguise of Avniel.
Physical appearance[]
It's a big clay rock creature with hollow black eyes, sharp teeth and it constantly drips wet paint or pieces of rock fall out.
Personality[]
It was immediately hostile after getting "accidently" summoned by Daphne and relentlessly chases those who are near the cave with the ancient manuscripts. Unlike most golems who follow their creators tasks when told, it doesn't do that and gets easily confused.
History[]
Scooby-Doo! World of Mystery[]
It was "supposedly" brought to life on accident by Daphne, who had read manuscript she translated for Professor Levi, which was the spell to summon it and it chased them out of the cave. It mainly targeted the gang while Levi ran off and hid.
It found the gang by the Dead Sea where it tried to attack them, but was stop for a little bit by Daphne, who tells it to sit down. Because Velma told her to try and command the creature since she supposedly summoned it (just like in the real mythology) and ended up getting the thing confused before immediately giving chase again.
It followed them back at the cave where they encountered Rivka, a farmer who owns the land by the cave and got tripped up by glass vases the gang took from her, leading him hitting his head against the wall.

Avniel unmasked.
The golem was unmasked revealing it to be Rivka's son Avniel, as she reveals he had been trying to distract everyone while she took the real manuscripts that Levi was going to find and replace them with fakes, all because she thinks anything will belong to her do to it being on her land.
