Cogwarts are part of Count Dregon's army. Count Dregon and his army, which includes Double Face, Fact, Plague Sentry, Cyclopter, and the Plague Patrol, had successfully captured Edenoi and enslaved the Edenoites. Count Dregon wanted the Masked Rider's powers as well. When Count Dregon spotted five costumed strangers (the Power Rangers) on the Edenoi, he assumed they were after Masked Rider's powers as well. Their headquarters, Spiderbase, began firing on the Rangers and Masked Rider. The Rangers and Masked Rider took cover. Count Dregon was furious. The Cogwarts, the Plague Sentry, and the Plague Patrol were sent down to hunt them down and destroyed them. The Rangers and Masked Rider left their shelter and faced them. The Cogwarts battled Masked Rider. White Ranger battled Plague Sentry and the rest of the Rangers battled the Plague Patrol.
The Cogwarts battled Masked Rider. After a difficult battle, the Cogwarts would be destroyed by Masked Rider.
