Continuing his power play, Kro-Tan's next step is to secretly attach miniature, mind-controled explosives to the Defenders and take Jedda captive. They arrive in Mongo, where he announces that they'll soon wed.

The witch who's aided Kro-Tan from the start manages to revive the original King of Mongo, and is revealed to be his Queen while having her youth restored. They lock Kro-Tan away and later do the same with the Defenders via a magical transportation. The King then disposes of his Queen. In the cell, Kro-Tan reveals that the King has returned, and the Phantom, after enhancing his strength, frees the Defenders. The showdown with the King is interrupted by the arrival of the creatures Kshin discovered earlier, whose singing brings about his downfall once again. Ming is restored, and angrily takes his son off for punishment.

Dr. Whitestead's plant food formula goes haywire--spilling on him and turning him into a plant! Ming seizes the scientist, the fomula, and his daughter. Lothar and Mandrake use their skills to save Whitestead, and the defenders must stop Ming from using the forumla to transform the whole planet into plants.

Eaons ago, a giant robot crash landed on Earth. Ming learns of The Annihilator, which now sleeps beneath Central City, and distracts all but one of The Defenders long enough to activate the robot.

The vengeful space princess Astra creates an army of clay soldiers. The daughter of Princess Aura, Astra is convinced by Ming that Flash Gordon was behind her mother's death. She uses blue clay from the Bandar village to create her army.

The incredible Hall of Wisdom pays its-2000-year, 24-hour visit to the Galaxy. It's a once-in-a-lifetime chance for Ming to get his hands on the dreaded Quasar Weapon, with which he can conquer the Earth.

Ming lures Kshin to Ice Station Earth by kidnapping Zuffy, then probes the dark side of Kshin's imagination to create fearsome warriors capable of destroying the Defenders. While the heroes work diligently to dismantle the Doomsday Warhead, a device left in the universe from an earlier holocaust, they are invaded by RADIAN, BI-NINJA, RIPPER, ZALZAR, JAMMER HEAD, and NEUTRON MAN, all products of Kshin's mind. Two of the evil warriors recapture the Doomsday Warhead and transport it to Ming's asteroid base, while the rest stay on to finish off the Defenders. Meanwhile, the young Defenders fly to Ice Station Earth to rescue Kshin. With the help of Dynak Y the super heroes trick the mind warriors into thinking they're dead. With Kshin free and the Doomsday Warhead moments from being launched against Earth, Kshin uses the good side of his imagination to make all the Defenders even stronger, enabling them to defeat the mind warriors and reset the guidance controls in the Doomsday Warhead, thereby blowing up Ming's asteriod base and saving Earth.

The Defenders add a new twist to the Battle Simulation Room--a Thought-Transference Cap. It transmits the wearer's imagination directly into the simulation; Kshin loves to use it to scare the other Defenders the best he can. But Ming the Merciless has found a way to tap into the Room. Using his ghastly power source, he can use his own evil thoughts and intensify them into reality! What starts out as a thrilling simulation under Kshin is taken over by Ming and turned into a terrible fight to the death in the all-too-real Haunted World. While the older Defenders fight monsters, harpies and skeleton warriors, the desperate young Defenders destroy the simulator and end the horror.

Ming is seeking the Jewels of Power, but a female archeologist named Atuskedero is also after them and travels to Tibet with Lothar and Mandrake (the latter worked with her in his pre-Defender days) to find the Jewels before Ming's forces do. But, when the trio discover the Jewels, it becomes clear that they have the power to hypnotise anyone who touches them. Can the remaining six Defenders reach their two companions in time to prevent an ancient legend - which predicts that the Dragon of Vengeance will appear if the Jewels are ever disturbed - from coming true?

Ming enlists the aid of the ruthless Beastmaster to create an army of Crystal Soldiers, beings grown from diamonds and invulnerable to everything except an extremely rare mineral called Orcite.

For Ming's plan to blanket the earth with a veneer of frost to be successful, the satellite requires the strength of a Starblue Crystal, of which only three exist. During a ceremony in which Mandrake donates his Starblue Crystal to the Central City Museum, the Defenders fight off an invasion by Ming's forces and capture two of his Men of Frost, Elgar and Zikry. Rick makes good use of a new invention which re-humanizes Men of Frost and Elgar tells the Defenders of Ming's plan to conquer earth. Zikry however, remains loyal to Ming and sabotages Dynak X before our heroes discover his true "evil" side. When Ming locates the last remaining Starblue Crystal he launches the satellite. It appears that it may be too late to stop Ming, but the Defenders fly out in their battle ships, engage Ming's roboships in an outer-space dog-fight, and explode the satellite with seconds to spare.

When the famous explorer Andrew Huxley encounters the wrath of Ming the Merciless while on expedition in Africa, he immediately calls in the Defenders. Ming kidnaps the Chief of the Bandar tribe after destroying their village, and forces him to lead the way to the hidden Temple of Pantheria. Before the Defenders depart for Africa they confine Kisa in a forcefield- for her own, as well as the other's, safety- leaving the key card with Kshin, under strict orders not to let Kisa out or give the key card to any-one else, especially Jedda. A short time later Kshin, disobeying direct orders, hands over the card to Jedda, who lets Kisa free. Meanwhile Ming reaches the Temple of Pantheria, locates the sacred tooth and with its powers orders Kisa to attack and destroy the Defenders. Kisa obeys, wreaking havoc all over Central City. Rick and Jedda track Kisa down and just as Rick is about to shoot her, the Defenders locate Ming in Africa and, with the help of Mandrake's illusory power, wrest control of the sacred tooth. He reverses Ming's orders just in time to save Kisa and our heroes.

The Defenders fly into space to investigate a mysterious comet and discover, too late to break from the tractor beams dragging them toward the comet, that in reality it is an Ilyrian spaceship. Inside the ship the Defenders are informed that they will be tried as the greatest criminals in the galaxy, with Ming as the accuser!! In exchange for his irrefutable evidence against the Defenders, the Evil One receives, under the pretense of "tools to rebuild the Earth", an anti-gravity device, a space warp drive, a machine to quadruple food harvests, and an energy shield to make all weapons obsolete, but these "tools" will actually serve to help Ming conquer the world. When the evidence is presented in court- film of the Defenders (actually Ming's Android Clones)- committing heinous crimes against the people of earth, things look bleak for our heroes. Rick, L.J. and Jedda manage to escape and invade Ice Station Earth, where they locate the androids and uncover Ming's plan. Back on the Ilyrian ship the Defenders are found guilty and sentenced to banishment to a galaxy 300 light years from earth, however just prior to their transport the young Defenders burst into the courtroom with the androids and save the day.

Ming's estranged daughter, Aura, crash lands her ship on Monitor and informs the Defenders of her father's latest scheme to enslave the population of earth with his Mind Neutralizer. Flash, an old friend of Aura's who once saved her and her husband, Barin, from destruction at the hands of Ming, immediately sets out for Grand Junction with Aura, Rick, Jedda and L.J. Upon arriving they discover that all the city's officials are already under Ming's hypnosis and that Aura's motivation is revenge- pure and simple. As Mandrake, the Phantom and Lothar rush to the rescue, the Defenders escape and convince Aura that she is an unwitting dupe in Ming's evil scheme. Briefly captured but now free, Mandrake and Lothar, with the Phantom set to work on reversing the polarity of Ming's neutralizer before he hypnotizes the entire world, while Flash, Rick, L.J., Jedda and Aura fly to an alien planet to rescue Barin. Seconds before Ming's scheme enslaves the world Dynak X completes the reversal, and all those previously under Ming's spell are once again free-thinkers.

Deep in Africa Ming locates an anti-energy source enabling him to open the Nightgiant Doorway and unleash 7-story tall nightgiants to destroy the earth. Flash flies out to space to destroy a Ming satellite, but his ship is immoblized by the Merciless One's roboships, while the Phantom goes to Africa to terminate Ming's activities in the Forgotten City. As the nightgiants terrorize various parts of the globe Rick intercepts a transmission from Ming to Garax and discovers that a transport invertor will eliminate the monsters. Mandrake, Lothar, Rick, L.J., Jedda, Kshin and Zuffy take on two nightgiants outside of Central City while racing to the stadium to retrieve the saving invertordevice. As they recover the device, Rick is captured by one of the creatures. Jedda departs for Africa, where her father will use the transport invertor to close the nightgiant doorway, while the other Defenders save Rick. Out in space Flash finally fights off all of Ming's minions and blows the satellite. Jedda delivers the transport invertor to the Phantom and they battle Ming's troops before employing the device and sending the nightgiants back to their own world.

While captives in Ming's jail, Rick and Jedda overhear Octon and Garax's plans to revolt against Ming. In exchange for their freedom, the Defenders offer to help in the scheme. When the uprising begins, Octon contacts Monitor in a plea for help, however Flash and the other Defenders recognize this as another in a long line of Ming's vile attempts to destroy the Defenders. Rick, L.J. and Jedda disagree and with Kshin and Zuffy as stowaways, the three fly off to Ice Station Earth to help defeat Ming. They arrive at Ming's devastated headquarters to discover that it is indeed another of Ming's schemes- the Three Sorcerers Of Teros created the illusion of a battle torn command center explicitly to lure the young Defenders there so that Ming can probe Rick's mind for the plans to Monitor's defense system. When Flash, Mandrake, Lothar and the Phantom arrive to rescue the kids they engage the Sorcerers in combat. Flash uses his sonic-ray blaster to destroy the crystals encircling the Sorcerers, while Mandrake and Lothar unstrap Rick from Ming's mind-draining device. United with Jedda and L.J., the Defenders of the Earth destabilize the shifting ice flow under Ice Station Earth before mounting their ships for the flight back to Monitor, once again victorious in battle- but yet to win the war.

After retrieving a vat of deadly mutant slime from Ming's laboratory, six of the Defenders (LJ and Kshin do not appear in this episode) are chased through a time warp and go back to the days of King Arthur. There, they meet and join forces with Prince Valiant who tells them that his wife, Alita, is being held prisoner by the evil Warlock who has stolen the fabled Eternity Stone. And, to further complicate matters, the mutant slime - which has already infected Mandrake - escaped from the Shuttle when the Defenders crashed into the sea and begins to spread.

The household helper robot, designed by Ming the Merciless in another of his evil schemes, is the hottest selling item on the market, deployed in over one million homes worldwide- including Monitor. Ming plans to use a space satellite to direct a hypno-beam through the robots to hypnotize their owners and make them slaves of the evil emperor. At the behest of Jedda, Rick examines his robot and discovers the plot, alerting the Defenders. When Flash flies out to space to destroy the satellite, he discovers Ming has a few tricks up his sleeve- a tractor beam renders his ship powerless and drags him towards Ice Station Earth!! Splitting up, Lothar, Mandrake and the Phantom penetrate Ming's fortress to save Flash. While Ming captures the Jamaican and the Magician, the Phantom wreaks havoc on the robot production lab. Ming activates his hypno-beam and sets the final stages of his plan into motion, however back at Monitor Rick mobilizes his frequency inhibitor, overloading the household helper robots and rendering them useless. Back at Ming's fortress, Mandrake uses telekenesis to overload the main generator, enabling he, Lothar and Flash to escape with the Phantom. As the robot production lab blows, Ming evacuates safely- surviving to return and fight another day.

When statues of ancient gods mysteriously come to life the Defenders are summoned to the Himalayas by Mandrake's old magic teacher, Theron. Our heroes learn that Ming and a mystic are behind the bizarre occurances, another element in a plan to recover a sacred dorje which will bestow upon Ming the power to rule the world. When Ming gains control of the sacred dorje, Mandrake tries to warn him about the danger of his mystic collaborator, but to no avail. The mystic snatches the dorje from Ming and uses it to turn himself back into Shiva- the destroyer god- who was banished from his dimension of Bodhidarma ages ago. As Shiva proclaims "Let the time of destruction begin" and he fades into his other dimension, Mandrake must follow. Ming, true to his cowardly nature, flees the scene, leaving the Defenders to amend the world-threatening situation he brought about. In the other dimension Mandrake battles valiantly against Shiva, however it appears his efforts are not enough to defeat the god, until an image of Theron appears and informs Mandrake that in Bodhidarma his illusory powers are REAL, not products of his imagination. Mandrake uses this nifty piece of information to conquer Shiva, and Lothar manages to open up the portal back to our earthly dimension just in time for Mandrake to slip through- with the powerful dorje.

When a two-hundred square mile area of Morocco mysteriously disappears, the Defenders investigate- sans Kshin, who is instructed to choose any book from Mandrake's library for a book report. While Kshin flips through the blank pages of a book titled "Enigmas", Flash, Rick, L.J. and Jedda enter the unexplained area and discover a primitive wall with a door in it. Suddenly the wall image appears in Kshin's book, along with an inscription telling how to get inside. As our heroes are nearly crushed by falling rocks, Kshin relays the information and stops the avalanche. Kshin, once again reading from the book, instructs the Defenders, who are now inside the shrine, to push the gold keys on the control panel, revealing the lost city and removing the jamming field surrounding the area. Mean-while Mandrake and Lothar track down a notorious jewel thief and recover the Eye of the Dragon which is missing from the wall. Back inside the shrine our heroes awaken the Sleeping God before Kshin warns them that he is unstoppable, and it looks like certain death for the Defenders. As Flash, Rick, L.J. and Jedda are about to be boiled in oil, Kshin arrives on the scene and convinces the creature that they are here to help; while Mandrake produces the crystal which will allow the Sleeping God to return home, thereby saving our Champions.

While engaging Ming's roboships in battle over the North African Desert, Flash discovers the remains of an ancient pyramid, where he finds an obelisk that produces visions when touched. The other Defenders arrive on the scene and Mandrake informs Flash that the sacred obelisk was believed to foretell the future. Unbeknownst to our heroes, Ming is in the area- in search of the very same obelisk, which he needs to tell the future so that he may propel his time drive device four-times the speed of light. When Rick and L.J. touch the obelisk they see themselves defeat Octon, giving them the confidence to set out for Ice Station Earth. They get as far as Ming's desert hideout, where they are taken prisoner. Mandrake informs our heroes that the obelisk cannot foretell the future, but rather what a person fears or desires for the future. Scavenger, the desert Arab whose home Ming commandeered as a base for his search, breaks free and sends for the Defenders, who raid Ming's headquarters. Mandrake destroys the evil emperor's time drive device, sending the obelisk beyond the reach of mortal men and Ming fleeing for the coolness of Ice Station Earth.

While on vacation in Jamaica with the Defenders, Kshin sees a ghost ship; however, no one believes him. Determined to get proof of the ship's existence, Kshin rows a dinghy out into the bay one night, and he not only finds the ship, but is taken on board by its ghost pirates!! Meanwhile our heroes are busy trying to figure out why Ming's roboships are in the area. Unbeknownst to them, the warlord is searching for Morgan's Compass, which he will use to turn the ghost pirates into his unconquerable slaves. On board the ship, the pirate captain tells Kshin that they have been searching for years for Morgan's Compass- the only object which can release them from their aimless wandering. Kshin offers help, and with the ghost first mate he goes ashore and returns with a sonic probe to locate the compass on the ocean floor. While Kshin is lowered into the water in a makeshift diving bell, Ming's roboships attempt to fire a freezebeam on the ship putting the ghosts in his power. However, the Defenders blow Ming's minions out of the sky! Kshin emerges with the compass, freeing the pirates and sending them on their way.

Dr. Kalihari's carnival is in town and the Defenders are on hand to see the show. What they don't know is that Dr. Kalihari has taken over the carnival from its owners and populated it with collaborators in his get-rich-quick scheme. Kalihari is infuriated when the Defenders embarass his mediocre performers, so to get revenge he dupes Kshin into unleashing a magic shrinking potion on them! Steadily getting smaller --until they will eventually vanish- our senior heroes battle Kalihari, his cohorts, dogs and common household items which pose significant obstacles to 3 inch people, before finally locating the magic antidote potion which restores them to their original size. Once again the "normal" Defenders of the Earth, they waste no time in disposing of Kalihari's gang and restoring the carnival to its rightful owners.

Dynak X picks up a bizarre energy transmission from Stonehenge prompting the elder Defenders to investigate. Kshin consults the book of enigma which shows him a blueprint of the ancient stone circle. In England, Flash, Lothar and the Phantom are lured inside Stonehenge by Kronos, a mysterious dark cloud, and turned into statues. Mandrake consults his old magic teacher, Theron, who informs him that Kronos is an evil monster who drove the great magician, Enigma, out of the Land of Magic, then destroyed the dimension. Kronos needs the book, which is actually the old master of magic in "book form", to materialize on Earth and destroy the planet. Our young heroes- including Kshin and the book, Enigma,- rush to the rescue; however, Rick, L.J. and jedda are also turned into statues by Kronos. Mandrake, with the help of Theron, fights off Kronos while Enigma guides Kshin into the Stonehenge circle, where he convinces Kronos to give him a blue crystal which allows Enigma to materialize and defeat the evil monster. The benevolent wizard then restores the Defenders to their natural state, before departing for the Land of Magic.

Ming knows that Flash Gordon is the only man alive who could effectively fly his state-of-the-art warplane The Scorpion, so he lures our hero to Ice Station Earth, where he has created four Flash Gordon clones! The evil warlord places Flash under his vile inquisitor with Flash's clones at the receiving end of the contraption to gather his exceptional flying skills. However, Flash brilliantly manages to dismantle the control box to the machine, therefore only facets of his personality are transferred to the clones. While the Defenders beat a hasty trail to Ice Station Earth, Flash wakes up in Ming's dungeon. When he again meets his clones he finds four distinct personalities- #1, an authoritarian; #2, a braggart fighter pilot; #3, an intellectual planner; and #4, a cool, Burt Reynolds type. Ming places clone #4, who has a bomb in his chest, in the dungeon so that the Defenders rescue him and bring him back to Monitor. Meanwhile he sends the other three against our heroes. Flash manages to escape from Ice Station Earth, destroys the three clones in a superb example of excellent dog-fighting, and confronts #4 in Monitor, disarming the bomb with seconds to spare.
