In another dimension, in a deep dark cave, Jedite remained trapped in an almost impenetrable crystal. He has been trapped in the crystal ever since Queen Beryl put him their for not defeating the Sailor Scouts. For four years he has been trying to break out of his prison, and finally he did when a powerful earthquake occurred. With the quake and the power he had left, he was free from his prison. Only one thing was on his mind now: revenge on the Sailor Scouts. He was weak and knew he couldn't take them on now. He needed an alliance with someone evil as he or more and powerful than him. He remembered searching through the dimension mirror at Beryl's Palace searching for someone who would help him defeat the scouts and he remembered who it was. Jedite left the dark cave in the pit of hell he was in to go back to Beryl's Palace. When he got there, no one was there and it looked wreaked.

Apparently Beryl was defeated by the scouts. Jedite thought.

He went to the dimension mirror and commanded for the dimension he was looking for to appear. Once it appeared, he stepped inside and saw a world unlike the world he had known. He knew he was in the right place when he saw dark red sky above four black obelisks and a black pyramid. Jedite went inside the pyramid and saw a bubbling cauldron and a tomb straight ahead.

"Mumm-Ra, the ever-living, come out of your tomb, I have a pact to make with you." Jedite said.

Mumm-Ra, who has been recuperating in his tomb for a year since his battle with Lion-O in the Book of Omens, opened his sarcophagus and came out. "Mumm-Ra, the ever-living, makes no pacts."

"Oh, I think you'll like this bargain. I know a way where we can get rid of your enemies, the Thundercats, and my enemies, the Sailor Scouts."

"How do you know about the Thundercats?" Mumm-Ra asked.

"I have seen you fight them from my dimension. I have a plan to turn the Thundercats to fight the Sailor Scouts."

"What is a Sailor Scout?" Mumm-Ra asked.

"Sailor Scouts are warrior girls with formidable powers; they have powers from nature in a way that-"

"Girls?" Mumm-Ra said surprised and insulted. "You think a bunch of girls are a match for the Thundercats?!"

"Never underestimate an enemy. I'm sure you are aware of that. Besides the Sailor Scouts are good and the Thundercats cannot fight good. They will surely defeat the Thundercats." Jedite explained.

"Impossible! Lion-O will convinced them not to fight once that Sword of Omens tell him they are good."

The Ancient Spirits of Evil eyes glowed. "Mumm-Ra, you have failed in you battles with the Thundercats in the past. Maybe a partner is what you need now. We will aid you Jedite and give you some of our power, but if you should fail, we will destroy you." They warned Jedite.

"I will not lose." Jedite told the Ancient Spirits of Evil.

"If things work my way, Lion-O will be stuck in another dimension, and I can take over New Thundera and 3rd Earth." Mumm-Ra said with a wicked smile and continued. "Your partnership is intriguing, Jedite. How would get them to fight each other?"

"Like I said before, I have a plan." Jedite said with an evil smirk.

In Tokyo, Japan near sunset, Serena was running to the movie theater to meet Darien for their date. They had been together since their daughter, Reeni returned to the future two years ago.

"I don't believe this. I'm gonna be late again. He can't expect me to be on time all the time." Serena panted as she continued to run. She turned around a corner and ran into someone. She figured it was Darien because she always run into him. But this time it wasn't Darien. It was Lion-O. "Oh, I'm sorry."

"It's okay." Lion-O said as he helped Serena up. "I'm glad I ran into you. I'm new here and I need help."

Serena stepped back to get a good look at Lion-o from head to toe. "Halloween was last month, pal."

"These are my regular clothes. However, I'm not sure how I got here. Let me show you where I came from." Lion-O offered.

"Well, you see, I have a boyfriend and I'm suppose to meet him and- whoa!" Serena said as was being dragged by Lion-O. "Hey, let go!"

"You're not going anywhere, you wretched Sailor Scout!" Lion-O growled at her and his eyes glowed an evil red.

On New Thundera, the sun has just risen and the Thundercat were busy at work. Although peace has been restored on their planet a year now, they still were busy with the restoration of their planet, rebuilding cites, and searching for refugees who were finding their way back to the planet they thought they had lost so long ago. Cheetara entered the Control Room and saw Lion-O on morning watch.

"I'll be back in a little while, Lion-O. I'm going on my morning run." Cheetara told him.

"All right. I'll see you later." Lion-O said.

Cheetara ran her normal 20 miles and began to practice using her telekinetic powers. Her powers finally developed two months ago. Even though she hasn't master it, she was learning about her powers at an incredible rate. After practicing for an hour, she was about to return home when a voice called for help.

"Help." A voice called.

Cheetara heard the voice behind her and turned around to see Tuxedo Mask. "Who are you?" Cheetara asked.

"Your enemy." He said and took out his cane and shot an electric charge at Cheetara that was so quick that even Cheetara couldn't have dodged. She fell unconscious into his arms.

"Sweet dreams, Cheetara." he said and his eyes glowed red behind the mask. He took a device out of his pocket that looked like a remote control and press the red button, opening to Beryl's Palace in another dimension. He carried her into a prison room and put her next to an unconscious Serena in a cage. He locked the cage and transformed himself into his true form-Mumm-Ra.

Jedite appeared beside him. "You've done well."

"I've completed my half of my part of the bargain-capturing Sailor Moon and Cheetara. All I have to do now is convinced the Sailor Scouts that Lion-O kidnapped Serena." Mumm-Ra said.

"And I'll convince Lion-O that Tuxedo Mask captured Cheetara."

"That impulsive fool will rush to save Cheetara without even thinking of the consequences of leaving a planet into the hands of evil." Mumm-Ra said and laughed wickedly.

"Yes, and if you are right and they don't fight each other, I'll still win. Without their leader, the scouts are powerless against me, especially with the extra power the Ancient Spirits of Evil have given me." Jedite said with a sinister look.

In Tokyo, Raye answered her phone. "Hello?'

"Raye? This is Darien."

"Hey, Darien. How are you?"

"I'm fine. Is Serena there? We had a date tonight and she didn't show up."

"Well, maybe she's running late. You know how Meatball head Serena can be."

"Yeah, I know, but she's never been an hour late. I'm getting worried." Darien said.

"An hour late?!" Raye shouted on the phone. "Even Serena wouldn't keep you waiting that long. Did you call Amy, Lita, and Mina?"

"I called all of them including her parents, and they haven't seen her."

"I'll call the others and we'll meet at the temple in 30 minutes." Raye told them.

A half an hour later, all the scouts, Luna and Artemis, and Darien met at the temple.

"The last time I saw her she was zooming out of the house to meet you, Darien." Luna told him.

"Is it possible that she ran into some trouble on her way to meet you, Darien?" Amy asked.

"I don't know, Amy. I-" The doorbell rang cutting him off.

Raye got up to answer the door. At the door, was a woman with a blue cloak. "I'm sorry, but were closed."

"I'm not here for business. I want to talk to you about your friend Serena."

Darien ran to the door and pushed Raye aside a little. "You've seen Serena?"

"Yes. I saw a man with fiery red hair wearing a blue tunic pulled her away from the public eye. His name was Lion-O and he's Lord of the Thundercats. I know him because he is an enemy of mine and he plans to capture all the Sailor Scouts because they defeated Queen Beryl and the Negaverse." the woman told Darien.

The other scouts came to the door. "Do you know where Serena is?" Darien asked.

"No, but I know he and his friends will be back at dawn at the park. That is all I know." She said and disappeared before their eyes.

"We'll be there and Lion-O will pay if he had harm Serena." Darien said and punched his fist into the wall.

The woman appeared at Beryl's palace and changed back into Mumm-Ra as he laughed. "That was too easy."

"Has anyone seen Cheetara?" Lion-O asked the other Thundercats, Tygra, Panthro, Bengali and WilyKit and WilyKat in the Counsel Room. Lynx-O and Pumyra were on 3rd Earth.

"I haven't seen her since she left on her morning run." Panthro said.

"Neither have I." Tygra added.

"Maybe the sword know." Lion-O said and pulled his Sword of Omens out. "Sword of Omens, give me sight beyond sight." He commanded

Through the hilts of the Sword of Omens, he saw Cheetara running and stopping to talk to Tuxedo Mask. He saw her being shocked and carried away. The eye closed. "Cheetara's been kidnapped by a masked man." Lion-O said angrily.

Just then Snarf and Snarfer ran into the room. "Lion-O! Cheetara's been kidnapped."

"5 minutes late, Snarf." Panthro said smartly. "The Sword of Omens told us."

"Did it tell you that a man witnessed it and he knows where she can be found?" Snarfer said sharply.

"Where's the witness?" Lion-O asked rising from his seat.

"Come in, Jedite." Snarfer said.

Jedite entered. "Lord Lion-O, I saw Tuxedo Mask capture Cheetara. I know it was him and he is an enemy of mine. He kidnapped her because he wants to drain her of her telekinetic power and use it to defeat me. I heard him mumble something about making her his love slave." He told the Thundercats. That last part ought to do the trick. Jedite thought.

"What?!" Lion-O roared

"Where can we find them?" Tygra asked.

"They are in another dimension. I can take you there."

"We're going now." Lion-O said authoritatively. "WilyKit. WilyKat. You two will stay here."

"But Lion-O-" the twins groaned.

"No buts. Tygra, Panthro, and Bengali, you're with me. That Tuxedo Mask will pay if he harmed Cheetara." Lion-O said angrily.

"Hey, wake up." A voice said.

Cheetara eyes fluttered and she moaned as she awaken. The first thing she saw was Serena looking at her. "Mmm. Wh-What happened?" She asked as she sat up against the wall and looked at Serena. "Who are you?"

"I'm Serena. Who are you?"

"I'm Cheetara. Where are we?"

"We're in a cage that's for sure. I haven't seen or heard anybody. All I know is some red-headed lion guy-"

"Lion-O?"

"I don't know what his name was but it could be him. Did he kidnapped you?" Serena asked.

"No. Did he have on a blue tunic, blue boots, and a blue belt with a symbol like mine?" Cheetara asked showing Serena her Thundercat insignia.

"Yeah. He did. Hey, you work with him. I see it now. He kidnapped you and you're pretending to be captured, but you're actual here to pump information out of me so you can control humanity." Serena blabbered.

"What?" Cheetara said confused. "No, that's not true. I was only asking to tell you that it couldn't have been him. He's good like me." Cheetara tried to explain.

"Yeah, right." Serena said not believing.

"It's true. The person who isn't good is the one who kidnapped me-some masked man in a tuxedo."

"Tuxedo Mask?!" Serena eyes widen. "Did he have a white mask, black hat and black cape and tuxedo."

"You know him?"

"Of course. He's my boyfriend."

"Some boyfriend." Cheetara said smartly.

"It wasn't Tuxedo Mask. It was an impostor. My Tuxedo Mask would never kidnapped anyone. He's good."

"That the same thing I said about Lion-O."

"Okay, you got a point. It was an impostor who kidnapped us." Serena said.

"The question now is: Who kidnapped us and why?"

"We did." Jedite said as he and Mumm-Ra stood at the door.

"Jedite." Serena gasped.

"Mumm-Ra. That can't be. Lion-O left you trapped in the Book of Omens." Cheetara said.

"Evil isn't so easily defeated." Mumm-Ra said as he walked closer to the cage.

Cheetara ran to the bars in order to attack Mumm-Ra but fell back weak. Serena caught her and pulled her to the wall. "Thundrainium." Cheetara murmured

"What have you done to her?" Serena demanded.

"She came to close to the cage bars. It's full of Thundrainum and it weakens her." Mumm-Ra said.

"What do you want with us?"

You two have already done your job. The Thundercats will fight Tuxedo Mask and the Sailor Scouts at dawn. They will destroy each other in the fight." Jedite told her.

"But why us?" Serena sounded confuse.

"I knew you were a bubble headed idiot, but I think you were this slowwitted. You are the leader of the Sailor Scouts and Cheetara is deeply special to Lord Lion-O. Need I go on." Jedite said.

Cheetara looked at her left arm and realized her staff was gone.

"Don't think about warning them, Cheetara. We have your staff and Sailor Moon's locket and communicator." Mumm-Ra said.

"By dawn we'll have what we want." Jedite said and he and Mumm-Ra vanished.

"Something's not right." Cheetara said aloud.

"What do you mean?" Serena asked.

"You heard Jedite said. 'They will destroy each other in the fight.' The Thundercats cannot fight anybody that are good."

"Yeah, but the Thundercats don't know that the Sailor Scouts are good."

"Right, but the Sword of Omens do. When it refuse to fight, Lion-O will realize the Sailor Scouts are good and order the Thundercats to stop fighting. Mumm-Ra and Jedite know this. So what are they really up to?"

"You got me, but Mumm-Ra is right. We can't get in contact with them. So what do we do? Serena asked.

"We have to wait until they come and get us. I know they will rescue us." Cheetara said confidently and sighed. "But until then, I guess we can talk so time will go by. I'd like to know what a Sailor Scout is?" Cheetara smiled.

"It's kind of a long story." Serena said.

"I think we have time, and afterwards I'll tell you about the Thundercats."

Near dawn, the Thundercats waited in hiding at the park, waiting for the Sailor Scouts. "I wonder what we are up against." Panthro said looking around.

"I'm wondering if we jumped into this a little too soon or if this is a trap." Tygra said to the group and they looked at him oddly. "Think about it. Where's Jedite? If the Sailor Scouts are his enemies why isn't he here to help us fight them?"

"Tygra does have a point." Bengali said.

The sun began to rise. "It's dawn." Lion-O said ignoring Tygra's comment. "I see them. Let's go." He ordered.

The Thundercats lined up in fighting position and Tuxedo Mask and the scouts lined up in front of the Thundercats. Lion-O and Tuxedo Mask eyed each other angrily.

"Tuxedo Mask is mine." Lion-O said to the Thundercats.

"Lion-O is mine." Tuxedo Mask told the Sailor Scouts.

Lion-O took out his Sword of Omens. "HO!" He commanded and the sword stretched.

Mumm-Ra and Jedite watched from a distance. "I told you it would work, Mumm-Ra."
