After his previous defeat, Cortex planned to use his power crystal to help him defeat the invaders.

With the crystals power, he was able to open a portal to the animated dimension and summon a minion as well, the Yenaldooshi. Cortex shot the Yenaldooshi, destroying it, with his ray gun and then fired a shot at Ghostfreak. This only enraged the alien, but Cortex tackled him back through the portal. Cortex then reclaimed the crystal in victory.
