Visitors from Falconia

Trapped in Black Cavern deep beneath Mystery Island, Sue is being slowly transformed into a birdwoman to be both princess and oracle for the Birdmen of Falconia, the aliens Dr. Strange accidentally transported to the island earlier. Meanwhile, Chuck separates from Sandy and P.O.P.S. during their search for Sue, leading to the latter two getting recaptured by Krieg and his men who bring them to Dr. Strange's cave. As Dr. Strange subjects P.O.P.S. to his own computer Titan, the energy process interrupts the Bird People's transformation of Sue. This leads the aliens to invade Dr. Strange's cave, turning off all power on Titan and placing everyone under their spell except for Chuck, who is outside the cave trying to find a way in.
