Antauri, sensing a disturbance in the Power Primate, heads off to see the ones who taught him the ways of the mystical energy. Fearful that his friend may not return, Chiro stows away in the Brain Scrambler, and joins Antauri on his mission. But upon arrival, things start to go south as the monkey's master informs him that the "Dark Ones" have returned and that the Power Primate is deteriorating - and proves himself a traitor as well. Now Chiro must fight his way past the temple's guardians to get to Antauri and stop Master Zan. But could the Power Primate be coming to an end? Guest appearance: Michael York as Master Zan
