The story begins with the Spinx suddenly stirs after thousands of years of been resting next to the Pyramids and takes off with Japan as its destination, spotted by fishermen and sailors; once on land, the Sphinx had developed a more define form, walking on all four legs and destroying a plant; the Monster comes under attack by a Tank Corp of the JSDF but these are quickly decimated. The Pollution Squad comes to see the monster moves in a straight line, indicating to George the creature is mechanical, and its confirm by Sally's equipment as it detect metal in her readings of the beast.

The team follows the monster and passes it, stopping in the middle of its path to arm a rocket like bomb, which propels and drills its way to the ground; the weapon explodes, causing damage to the Monster, stopping it on its tracks, but temporarily as the Sphinx is fix and continues its march, with John discovering the Atomic Power Station, which is also storing a new fuel (Flameon) is on the monster's path. The group after warning the facility, head to the village which is in the path of the creature, where (after meeting two kids) proceed to plant explosives on a bridge; the Sphinx arrives and the Blast go off, making it fall into the river canyon below, though they come to see the kids from before were also down there; they take refuge from the rubble in a cave, but are trap by the debris.

As the others come to their rescue, Sally, Arthur and George are attacked by Robe Arab men and frozen by their laser weapons and are taken for search, presumably looking for Spectreman, but Otto attacks them, taking one of the weapons and freeing George and the others, and followed the Arab men and battle them in the field, with George going after and catching up with the leader. In their scuffle, a shot from the others removes the mask off, revealing to be Karas – and thus, the machinations of Gori been behind this.

Their fight is however halted by the reawakening of the Monster, now in its new more bestial form, thanks to Gori's intervention; the monster walks away, opening the cave allowing the kids to leave and finding Arthur and the others, just as Spectreman arrives to battle the newly reform Monster. The giants battle, and Spectreman is able to hold off the creature, tossing it all over the place and then taking it to the air, when suddenly, the Monster Explodes.

Spectreman is presume dead erroneously by Karas and Gori begins repairing its monster, meanwhile The Team try to help by cutting branches to allow him have contact with Overlord; cutting the branches help achieve contact and Overlord is able to recharge the Cyborg, who then thanks his allies and depart. The group then searches for George when they come to see the Sphinx monster was alive, now in a Spider like form and continuing its march towards the station. George catches up with the others and the team head back to the station, but their way is soon block by High voltage webs, forcing the group to continue their path on foot, as a tank company are decimated by these. Meanwhile, the group come to get caught by some of the webs left by the monster and are able to repel the beast with their Heat rays, George the helps the others to get free.

In the lab, with the help of a mummy robot, Karas and Gori take over the lab and begin to take the fuel. Meanwhile, with the help of the kids, they use a secret path of theirs to the Lab, but on the way, one of them falls to the webs; Arthur and George try to rescue him, but in that moment, Overlord contact, allowing our hero to Transform to face the Monster.
In the battle however, Sphinx Spider is able to fire one of its limbs close to Spectreman's legs, which releases a web string that sticks to his legs; this cause him to lose balance and fall into one of the bigger webs; the monster begins to cocoon him with its strings. The beast then tries to bite him to suck its power our, but with its cutters, Spectreman breaks free and kicks the monster off of him.

In the meantime, Gori takes the fuel and flies away, leaving the Mummy Robot to deal with the Doctor and John, but Arthur and the others arrive on time to gun down the creature, while Spectreman finally finishes the Monster off by cutting its limbs, then tossing it away to have it been eviscerated with Spectre Flash. After the battle, George finds the kid alright. George gathers with the others, but their reunion is cut short as the whole facility suddenly explodes thanks to a bomb planted by Karas; George coming to realize the monster was a diversion to Gori's real plan, to steal the fuel and succeeded on his first major tactical victory.

# The Mummy Robot was like the most random ass thing in this whole episode, really,, despite the Egypt Monster theme in it. They could have had Karas causing the same trouble.
