From here the OmicronPsy Network, invented by scientific genius Emperor Jarad, controls the world.
The only thing Jarad can do to save mankind is to change history-by going back seven years in time and shutting down OmicronPsy's Zentrium CPU.
After subduing him, OmicronPsy decides to brainwash him and send Quantum back 7 years to assassinate Jarad.
At Zentrix, OmicronPsy repairs the time machine and speeds up the development of the Dark-Series robots.
In the forest, the Peachi-Wigis tell Megan that Dr Roark has sought refuge in the Pyramid.
Yet, Zeus suddenly encounters statics, and is forcefully turned back into lock mode, and is having trouble fighting against Dark-Alpha.
Back in the desert, just as Zeus is having trouble with his power system, Megan gets attacked by the Big Tooth Bug.
But since Zeus has lost his flight function, their journey across the desert to the Pyramid is taking so long that Megan is in danger of dying of thirst.
After a precipitous fall down an escape chute, Megan and party land in a kind of warehouse, where they are again attacked by the pursuing Dark-01.
Deep in the Pyramid foundations, Megan locates the mini-submarine, in which they make good their escape.
In order to repay Nick for rescuing them, Megan decides to help him destroy the Monster that killed his father.
Nick tells Megan he doesn't like the way she just treats Zeus as a piece of expendable hardware and lectures her on the subject of friendship.
A mysterious girl called Akina, who is actually Dr Coy's daughter, arrives with her robot, Fighter.
After Fighter has beaten their robots, The Blade and Hell Tank, she issues a direct challenge to Dr Coy.
Returning to the laboratory on Dr Coy's truck, Megan learns how Dr Coy and her father fell out over the Zentrium biochip specification, and tells her that his is against towards giving so much thinking power to OmicronPsy, worrying that they may eventually turn against them.
As he was knocked out by Quantum, he was further powered up by the Zentrium and transformed into Fighting mode, due to his faith for everybody.
He orders Dark-04 and Silver-03 to go and mount guard at the Volcano Stronghold, where Silver-03 then encounters the RockMen who live in the vicinity.
When the newly fixed Quantum leaves Dr Coy's laboratory, he wanders aimlessly trying to rediscover a sense of his own value, until he encounters Webster the BirdMan.
At this moment, Megan and Nick are hit by a snowstorm and get socked in on an ice floe at the South Pole.
Setting off in search of the Snow-Stronghold, Megan slips off a cliff and is saved just in time by a penguin tribe.
Dr. Coy gives Zeus a rocket kit to double his flying speed in the upcoming battle at the Sky-Stronghold.
Dr. Coy also upgrades the robots and enlists the help of Blade and HellTank for the upcoming battle at the Space-Stronghold.
Megan and Nick are losing ground as they fight off OmicronPsy's huge fleet of flying robots until Zeus comes to the rescue.
Quantum is serious damaged by OmicronPsy, realizing that he's not going to survive, temporarily blocks the attack with his shield, gives Zeus his Zentrium and dies.
He managed to boost the Zentrium chips' full power and entered golden mode and drags OmicronPsy into the time machine.
After Megan's struggle inside her heart, she finally activates the time machine and sends them both into Stone Age.
