Pandemonica is the first demon encountered in Helltaker, and is a customer service representative in Hell. She is initially referred to as "The Tired Demon", but this is later changed to "The Sadistic Demon" in the game's ending.

Pandemonica was originally full of all of Vanripper's favorite traits, like being socially awkward but polite, archaic in an elegant way, and a tired hard worker.
