A space kaiju brought to Earth by Alien Ghose, the ghost phantom, as part of their invasion. Pandon has two heads, attacks with powerful flamethrowers from both mouths, and is also adept at physical combat by utilizing its super strength and agile movements.

Pandon flew to Earth in the Pandon Carrier, Alien Ghose's special spacecraft. It faced off against the Ultra Guard and pushed them back with its flamethrowers. It was about to drop a boulder on the Ultra Guard’s heads, but was stopped as Dan Moroboshi transformed into Ultraseven and engaged it in combat.

Ultraseven was unable to use his full strength due to extreme fatigue, so Pandon was able to dominate him with kicks and punches at first. However, as it was distracted by the charging Ultra Hawk 3, Ultraseven used the opportunity to defeat it by severing off its left arm and right leg with his Eye Slugger.

The body of the defeated Pandon was recovered by Alien Ghose, who then substituted its missing body parts with machinery to turn it into Reconstructed Pandon.
