Sailor moon was battling Rubeus on his space ship and even with the gravity crystal she was still having a hard time fighting him. Rubeus was laughing seeing the young scout struggle. Chibi-usa knew that there was nothing more she could do to help. She was starting to lose hope in Sailor moon defeating Rubeus. Even Diana was starting to lose hope. Sailor moon was getting very agitated that this dark moon member was threatening to erase everything in her world.

"Give up, sailor brat! You lost!" Rubeus said

"You dark moon jerks kidnapped my friends twice and are trying to destroy my world. I will stop you with every ounce of power that I possess!" Sailor moon said

Moon's anger against Rubeus was starting to trigger a transformation that hasn't happened in a long while. She wanted revenge against the black moon clan and they were going to face her wrath.

Chibi-usa sensed a rise in power coming from Sailor moon. She didn't where she got all this power from but she and Diana were hoping that it would be enough to take Rubeus down. Moon changed forms and was now looking at Rubeus with an intent to kill.

"She changed forms" Diana said

"I can sense a massive amount of power coming from her" Chibi-usa said

Rubeus was taken off guard by the sailor scout's new form but he shrugged it off since he believed that he still stood a chance against her.

"It doesn't matter how many times you transform you will soon fall in defeat by my hand" Rubeus said

Rubeus sent out a blast of dark energy at Moon, but she deflected it and she didn't even need to use her sword to stop it. His eyes went wide in shock after seeing that his attacked was easily deflected by her. He attacked her again but his attack was deflected again. He sent out a dark energy beam at her and she responded by holding up her hand. She stopped it and destroyed it. He tried to use it again and this time Moon didn't just stop it, she sent it right back at him.

Rubeus screamed in pain as he felt his own attack hit him. He was on one knee and was panting heavily.

"What's going on here? I was beating her a minute ago! Now she's the one who's beating me! What the hell happened to her?" Rubeus thought

Rubeus did know that magic projectiles didn't work on her. She would deflect, destroy or send the attacks back at him. He did know that it should be impossible for her to deflect all of his attacks if they were coming at her in separate directions. He launched a bunch dark orbs and made go at her in different directions.

Rubeus smirked thinking that he had finally managed to defeat her but the smirk was wiped off of his face when he saw that Sailor Moon had erected a white barrier around herself.

"No way! That's not possible!" Rubeus said

Chibi-usa was shocked to see this display of power. It was now clear that Sailor moon had so much more power than she did and the black moon clan were after her for her power. The power that Chibi-usa possessed pales in comparison to Moon's power.

One of the attacks that got deflected was headed for her. She screamed and hoped that Sailor moon would save her but she didn't and Diana pushed her out of the way. The young kitten also managed to dodge it before it hit.

Chibi-usa and Diana had to avoid attack after attack because Sailor moon was deflecting all attacks that were being sent her way.

"Sailor moon! Stop it! We're almost getting hit by those attacks!" Chibi-usa said

Chibi-usa froze when Sailor moon shifted her gaze towards her. All the kindness that she once held was gone and was replaced by anger.

Rubeus couldn't take it anymore and shout at her.

"What the hell are you?!" Rubeus asked

Moon shifted her gaze back over to Rubeus and told him what she was.

"I am a princess that desires revenge above everything else. I am Princess Sailor moon. The only one who will be destroying this world is me" Sailor moon said

Serenity pointed her open hand at him and released a pink blast that severely injured him. His dark power was weakened enough that the sailor scouts that were being held prisoner by his power released them.

The sailor scouts looked around and saw that they were inside the spaceship that Rubeus kidnapped them with. They looked forward and to their horror they saw Princess Sailor Moon was there.

"This is not good" Venus said

"Sailor scouts" Serenity said

Everyone looked at her.

"Your precious Usagi had to rely on her true power and now the time has come for me to take my revenge on the earth" Serenity said

"We can't let you do that" Mars said

Mars had an evil charm out was ready to use it on their dear friend.

"That charm won't work on me, Mars" Moon said

"How do you that?" Mars asked

"Usagi and I are the same person. We share same spirit, we share the same soul. There is nothing you can do to repel me. The only way to stop me is to ether seal me away or kill me and I know of you have the heart to do that. Even your powers combined are no match against mine" Serenity said

"Usagi! Stop it!" Chibi-usa said

Serenity looked at the young pink haired girl.

"I am Serenity right now. I am no longer Usagi" Serenity said

The ship that they were in was shaking and saw about to explode. Rubeus used the last of his breath to make this ship self-destruct. The scouts knew that the only way they could leave was by teleporting but with Usagi as Serenity right now, they doubt that she would cooperate. Serenity felt that this place was about to destroy itself and she decided to set her revenge aside for now. If she were to awaken in the future where Chibi-usa and Diana come from, then she would take her revenge there.

Everyone closed their eyes, waiting for death but it never came. In fact they felt a surge of power and when they opened their eyes again they saw that they were back in

Tokyo.

"How did we get here?" Mercury asked

Everyone looked around and saw Serenity there.

"Serenity? Did you save us?" Venus asked

"All of you are still needed in the world of the living. I will hold off my revenge for now, but sooner or later I will destroy this world" Serenity said

Serenity changed back into Usagi and she collapsed. The sailor scouts were starting to wonder if there was a way for their leader to control this power.
