Conan the Adventurer (1992 TV series)

Conan the Adventurer was a 1992-1993 American-Canadian animated series created by Sunbow Productions for first-run syndication. It follows the adventures of Conan the Barbarian and his friends as they search for a way to free Conan's family from a "curse of living stone." The series is loosely based on the 1930s pulp comics character created by Robert Howard.

Seven Against Stygia (Season 1, Episode 13)
Conan and his allies set out to prevent Rath-Amon from completing the second pyramid that will allow him to summon his god Set. During their confrontation with the sorcerer, Conan gets sucked through a portal into the dimension where Set is imprisonned and finds himself face to face with the giant serpent. Conan is immediately hypnotized by his gaze. Only the intervention of his friend Needle prevents Set from devouring Conan.

The Queen of Stygia (Season 2, Episode 23)
Conan is lured into a trap by Queen Mesmira. She uses a medallion to put Conan under her spell and has him steal his friends’ weapons. Once he has done this, they both confront Rath-Amon for ownership of his black ring, the source of his magic. During the fight, Jezmine and Greywolf arrive and shatter the Mesmira’s medallion. This snaps Conan out of his trance and the queen is forced to flee.

City of the Burning Skull (Season 2, Episode 25)
Conan helps the people of a mysterious "lost city" battle an evil sorcerer who is using them to prolong his own lifespan. The sorcerer uses mind control on Conan's companion Jezmine and turns her against the others. Conan discovers that the sorcerer's skull mask is actually a living entity that controls its wearer, and smashes the mask to put an end to the reign of terror.
