The Mind Warriors, Part I - S1.E11

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.
