On the ship, the Joker, Harley, and Mojo are enjoying the destruction going about Townsville. "This is way much better than a joke!" laughs the Joker. Batman and Blossom catches up with the ship. Blossom uses her heat vision to create a hole in the roof. Then she and Batman enter the ship. "Alright enough fooling around." Says Blossom. The Joker turns around and sees them standing right there. "Stay with the control," he says to Mojo, "I'll give our guests a little greeting. He gets up and goes over to fight Batman and Blossom.
Meanwhile Bubbles and Buttercup are dodging the X laser blasts being fired at them. Buttercup uses her heat vision to disarm some of them. "Buttercup!" cries Bubbles, "Look out!" Buttercup looks and sees another cannon about to fire at them. They quickly dodge it. "Come on Bubbles." Says Buttercup as she and Bubbles fly over to blast the cannons. Meanwhile Batman and Blossom are battling the Joker on the ship. The Joker takes out a chain and swings it at Batman. This provokes him to fight back. As the two fought, Blossom flies over to attack Mojo Jojo. As they struggle, he falls off the seat. "Alright fine." Says Harley Quinn as she goes over to take the controls.
Meanwhile Bubbles and Buttercup use a super laser to blast all of the cannons out. "Yes!" they cheered, "We did it! We did it!" But their victory was cut off by a last cannon coming out from the ground. It contains the last ounce of Chemical X. It starts to fire blasts that can wipe out their powers via a single shot. They quickly dodge every single shot. "Bubbles," says Buttercup, "let's use our mega ultra-super force field." Bubbles and Buttercup hold hands and spin really fast into a magnetic force field. The blast gets deflected back to the cannon, destroying it whole. "Yes!" cheers Bubbles, "Let's go help Batman and Blossom." They fly out of the observatory to the ship.
On the ship, Joker takes out another bag of explosive marbles. But Batman kicks it out of his hands. The marbles roll around exploding one by one. Bubbles and Buttercup arrive onto the ship. "It's gonna blow." Says Batman, "I'll get Quinn. You three take Mojo." He goes over to the control seat and lifts up Harley Quinn while Blossom, Bubbles, and Buttercup grab Mojo. They all evacuate the ship, leaving the Joker to be exterminated by the explosives. Batman's parachute opens as he carries Harley. Meanwhile the Joker has prepared some parachutes for an evacuation, but the explosion sends him to the ground. As the ship gets ready to explode, he takes the last moment for the last laugh. As the Powerpuff Girls, carry Mojo Jojo away, the ship explodes and goes down. "Puddin'!" cries Harley sadly. "At this point," says Batman, "he most likely is." The Powerpuff girls put Mojo safely onto the ground. "Thank you girls." He says, "I knew that you three would someday be of service to me." "Oh we never were." Says Blossom. And with that the three start to pummel Mojo and send him into the jail van.
