After awhile, the Impossibles were called into Big D's office. Phyllis had told them they were fighting, and he wanted to know what started it.

"You boys are supposed to be a team," he said.

"Yeah, well, I don't want to be a team anymore," Coiley said.

"Right," Multi and Fluey said in unison.

"They've been arguing non stop since last night," Phyllis said, with a shrug. "I'm sorry, chief, I don't know what to do."

"I don't know how it happened," Big D said. "But they're just going to have to make the best of the situation. I can't take them off the Siren case now."

"Then just take Multi and Fluey off, Big D," Coiley said. "I can handle the Siren."

"Yeah right," Fluey said. "I'm more competent than Chubby over here. I can take the Siren any day."

"He's got water on the brain if he thinks that!" Multi shouted. "Let me go after the Siren myself, chief."

Big D and Phyllis glanced at each other. They decided not to take any of them off the case. They would just have to try to remember that they were a team, but that was easier said than done. The Impossibles left the room and went their separate ways. After awhile, Mike called them into the garage.

"Okay, you guys wanted your own wheels," he said. "So here you go."

Mike opened a curtain and revealed a green and blue motorcycle, a red and black car, and a purple jet.

"I color coordinated them for you," he replied. "I gotta tell you, I staid up all night on these things. Now if there's nothin' else you want from me, I have to fix the Impossi-Mobile."

The Impossibles didn't say anything. They didn't even thank Mike for his hard work. They just boarded their new vehicles and took off. They didn't even make contact with each other for the rest of the day. Fluey parked his motorcycle outside the malt shop and began practicing his guitar. Multi drove around town, parking behind the school's football field and worked on his own songs. Coiley flew his jet to the city park and practiced there.

In the meantime, the Siren was preparing the final step in Mission Impossibles. She and the Serenes stood in her control room, planning everything out.

"I'm going into town and snatch some supplies," she said. "Professor McDonald will need them to mix the formula. That will also lead the Impossibles here. Your job, girls, is to wait in the three tunnels, and lead them to me."

"What are you going to do once they're inside, Siren?" Shawn asked.

"That's my little secret," the Siren said. "You just get them here."

The Serenes nodded and took their places in the tunnel. The Siren laughed and hopped in her own jet and took off towards the city. She broke into State U and began gathering chemicals, test tubes, flasks, and the like. As she was gathering her material, Professor Questology entered the room.

"You!" he shouted.

"You got that right, doc," the Siren said. "That formula's going to make me a rich woman! See you around, Pops!"

The Siren took her supplies and headed for her jet. Then she took to the air, blasting off. Professor Questology watched her go, and then picked up the phone. He called the SSH right away.

"I need the Impossibles!" he shouted. "The Siren was just here!"

"We'll do what we can, professor," Phyllis said. She hung up the phone and then buzzed Big D. "The Siren's struck again, boss. We need the Impossibles."

"All right," Big D said.

At the moment, Coiley's guitar began to beep. He stopped strumming immediately.

"What do you need, chief?" he asked.

"The Siren has struck again," Big D replied.

"I'm on it!"

Coiley hopped into his jet and turned on the turbo speed. When he did that, he changed into his superhero costume and was off.

"Rally ho!" he called.

Then, Big D buzzed Multi on his guitar.

"The Siren is on the loose," he said. "Go after her."

"You got it, Big D," Multi said, and he put his car into turbo drive, and changed into his own costume.

"Rally ho!" he cried.

Next, Big D got in touch with Fluey on his wrist TV.

"I need you to go after the Siren," he said. "The world's safety depends on it."

"Gotcha, chief!" Fluey shouted, and started up his bike. He took off and changed into his costume as well.

"Rally ho-ho!" he shouted.

The three Impossibles were off. And wouldn't you know, they arrived at the exact same time.

"What are you doing here?" all three asked at the exact same time. "Big D called me to stop the Siren."

"Oh he did, did he?" Coiley asked. "Well, sorry, fellas, but I'm handling this job!"

"Fat chance," Multi said. "This one's mine!"

"You're both out of luck!" Fluey shouted. "This job's mine!"

"Rally ho!" the three of them shouted, and dashed through separate tunnels.

Coiley bounced along as fast as he could. He ran into Natalie.

"Coiley, I'm so glad I found you!" she shouted. "The Siren's here, and she's going to force Professor McDonald to mix up his formula! Quick, I know a shortcut!"

"Lead the way, Natalie!" Coiley shouted, and he followed Natalie down the tunnel.

Fluey practically soared through the tunnel with the power of a river. Cindy grabbed his hand as he went flying by her.

"This way, Fluey!" she shouted. "I know a shortcut!"

"Hey, great, Cindy!" Fluey said.

Cindy led Fluey up a flight of stairs behind the wall. Multi was running down the third tunnel, when he ran into Shawn, literally. Both of them fell to the ground.

"Sorry, Multi," she said, standing up. "But I have to tell you something. It's the Siren. She's . . . . ."

"Is she here?" Multi asked.

"Well, yes, but . . . ."

"Where?"

"In her lab, down that way. But I have to warn you . . . ."

"Thanks, Shawn!"

"But Multi!"

Too late. Multi was long gone. Shawn followed him down the passage anyway. She just had to warn him that a trap was in store for him, Fluey, and Coiley. The six arrived at the lab, and looked around.

"This has got to be the Siren's lab," Fluey said.

"You're perceptive, Fluid Man," the Siren said, coming into the lab. "Perceptive, but stupid. You fools fell right into my trap!"

"Trap?!" Coiley shouted.

"Of course," the Siren said. "My little girls fooled you into coming to my lab. Now I have you where I want you."

"What do you mean your girls?" Multi asked.

"The Serenes, of course," the Siren laughed. "You didn't honestly think they really liked you, did you?"

"Our job was to turn you against each other," Cindy said. "And it worked!"

"You mean you didn't really like us?" Coiley asked.

"Get real!" Natalie shouted. "You guys are just freaks of nature!"

"It was all just a trick?" Fluey asked.

"And you saps fell for it!" Cindy laughed.

The Impossibles looked at each other and then glared at the Siren.

"I think it's time for a little teamwork, fellas," Coiley said.

"Right, Coiley!" Multi and Fluey shouted in unison.

"Rally ho!" Coiley shouted, and charged the Siren and the Serenes. The Siren was prepared, though. She took her amulet and zapped Coiley with it. Immediately, his clothes changed back to his rock and roller costume. He fell to the ground after that happened.

"Hey, what happened?" Coiley asked.

"Don't worry, Coiley, I'll get her," Fluey said, and turned into water in order to charge the Siren. "Rally ho-ho!"

The Siren laughed and aimed her amulet at Fluey. She zapped him, and the same thing that happened to Coiley happened to him, too. He crashed to the ground. Then it was Multi's turn.

"Rally ho!" he shouted, multiplying.

"Child's play," the Siren said. She held her amulet and zapped all the Multi Men, including the original. His costume changed, and he crashed right into Coiley and Fluey. All three of them were confused as could be.

"What just happened?" Fluey asked.

"Yeah, what did she do?" Coiley asked.

"I stole your powers!" the Siren shouted. "The super Impossibles aren't so super anymore! Get them, girls!"

Cindy, Natalie, and Shawn jumped on the boys, in order to subdue them. The Impossibles couldn't fight back, because of their morals. They couldn't bring themselves to hit girls, so quickly, the three of them were tied together back to back.

"Excellent, girls," the Siren said. "Now, we'll dispose of them."

The Impossibles were taken to the Siren's torture chamber. They were thrown down a large hole, and then chained to the wall by their wrists. The three of them looked up at the Siren and the Serenes.

"What are you gonna do with us?" Multi asked.

"I'm so glad you asked, Multi Man," the Siren said. "Since you three are powerless, I had a hard time deciding on what exactly to do with you. So I decided to throw you into my sewer drain, and turn the water on to full blast, and I've taken the liberty in plugging the drain, which can only be unplugged by the switch up here with me."

"So you're planning on drowning us," Fluey said.

"I hope you boys can hold your breath for a long time!" the Siren shouted. "Okay, Shawnie! Turn on the water!"

Shawn hesitated for a minute. She hadn't said much during this whole time. Multi looked at her.

"Shawn, don't!" he shouted. "I know you're not like them! You're not evil like the rest of them!"

"Don't listen to him, Shawnie," the Siren said. "He's a rock and roller. Rock and roller just break hearts."

"Please Shawn! Don't do it!"

"Do it, Shawn. He'll just break your heart."

Shawn took a deep breath and grabbed the lever.

"I'm sorry, Multi," she whispered, and yanked.
