The Middle is when Julie Parker was performing magic tricks. Her next trick was to slice something in half and put it back together. Terk chooses Tantor but he was too depressed and he goes out. He hears noises and warns everyone, except nobody believes him. Venus takes a look out there, stating she doesn't see anything. But the TechMen of UNDERWORLD pop out and kidnap Venus.
Tarzan tries to save Venus but fails. Everyone faints, and the Techman runs off with her.
They are going on a trip to THE UNDERWORLD, where Kigwala was a part of, and on the way Tha runs away from a Techmonster chasing her. Tarzan sees this and he attacks the Monster. Tarzan asks her the location of Venus, but Tha replies saying she doesn't know. Then Tarzan told Tha what happened and she starts acting innocently.
Then, back in Opar, a Techman gives Venus Tha's staff. The Techmen bow down and Venus reveals her true techman form, as her eyes started glowing. Back in the forest, Tha says she'll "help" Tarzan rescue Venus, but Venus is a lot older than anyone thinks, she is about a hundred years old.
Tha and Tarzan sneak in the castle. Tarzan sees Venus and Tha states she'll grab her staff while he stops the Techmen. Tha regains her staff and stops the Techmen.
