What Lycidias Beneath (S02E49)

Mavis sets out to master the Vamp Stamp, a legendary technique from her ancestor Lycidias Dracula that sends shockwaves powerful enough to repel both monsters and humans. However, her efforts awaken a buried menace when she inadvertently disturbs his ancient tomb. With chaos looming, Dracula returns to assist Mavis and her brother in thwarting their ancestor's attempts to reclaim dominance over the monster realm and free Mavis from his grip. In the end, Mavis successfully executes the Vamp Stamp, imprisoning Lycidias' spirit in Klaus' smoothie cup, confined to the basement. Dracula chooses to stay at the Hotel, ready to face any future threats. Unfortunately, Wendy shatters a glass lantern, releasing Lycidias' malevolent essence, which threatens both the Underworld and the monster world.
