While the Team was out flying in Miss Martian's Bio-Ship, Red Tornado learned an emergency alert was triggered at the Happy Harbor Power Plant. The Team investigated and discovered it was being attacked by a new villain named Mister Twister. Their battle caused much property damage to the plant, harbor, and city.[2]
The Team set up a perimeter around Happy Harbor High School to safeguard Dr. Serling Roquette while she completed a virus to neutralize the Fog. Upon an incursion by Cheshire, the Team moved Roquette across the town to the Sandbar internet café while Miss Martian posed as Roquette at another location.[3]
Megan, Conner and Wally went to the school's Halloween party. They pranked Marvin White, who had hoped to prank his schoolmates with a fake Martian invasion.[5]
With all adults gone due to a spell from Klarion, the Team used the high school as a base to shelter as many children as possible. The older children helped out.[6]
The people of Happy Harbor witnessed a large explosion in nearby Mount Justice. Mal Duncan, who had just arrived from Ivy Town, saw it too, and rushed to aid his friends.[1]
