Spydex

Both Gnatu and Spydex attacked the city of Briarwood, and began draining Life Force from people in the park. The Mystic Force Rangers soon showed up, but were forced to deal with the Hidiacs first. The Yellow Ranger did manage to get to Gnatu and battle her, but she was too strong for him. Both Gnatu and Spydex then managed to escape, with the stolen Life Force.

Later, Spydex lured the Rangers into battle at a power plant. The Red Ranger was successful in getting the Life Force out of Spydex, but Gnatu stole it away from the Rangers. Spydex then tried to escape, but the Rangers followed him on their Mystic Racers. When they caught back up with him, he had spun a spider web atop the city, and they had to battle him on the web. The Yellow Ranger used the Mystic Force Fighters to take the spider creature down. But this wouldn't last, as Spydex grew large. The Rangers formed the Titan Megazord and battled the monster. They were able to get the Life Force Orb out of the monster again. However, Gnatu attacked the Rangers before they could obtain the orb. With the Life Force still in their control, the evil duo escape once more. They both returned to the city to steal more Life Force. The Red, Green, Pink and Blue Rangers jumped into action and fought against the twosome. The Rangers were still outmatched, and Gnatu prepared to fire the now Dark Life Force Orb into the sky, thus attacking the city with an explosion. Before the orb was fired, the Yellow Ranger arrived and put a stop to Gnatu's plan. The Solaris Knight was then able to get the Dark Orb out of the firing device. The Mystic Force Rangers attacked Gnatu and Spydex with the Magi Staff Speed Spell. With this attack, the Rangers had the advantage. Yellow Ranger was successful in destroying Spydex with his Magi Staff. After Spydex was destroyed, all the Life Force was returned to those it was stolen from.
