AN: (-‸ლ) I have another 「What If」 scenario in my head. This time it was because of the Earth Prince's jealousy if he ever found out where Serenity Usagi was. ε-(ーдー) Anyways, the 「What If」 scenario is this:

What if a certain prince found said certain princess?

What if that prince became jealous and akumatized?

What if something new came out of it?

Well, to answer these questions, this one shot got created. (^^;) This will actually be a follow up one shot because I really want Serena, and to an extent Chloé, to know Cat Noir's identity. (^^ゞWithout further ado! Read on with these 「What If」 questions in mind. |ω・`)


"Found her," said a male voice.

There was a male tourist who flew into Paris, France the night before. Said male had dark bluish-black hair and deep blue eyes that were hidden behind sunglasses. Said male was also wearing a black turtleneck, indigo pants pulled up to his waist with a bright light brown belt, a green sweater jacket, and black loafers. Said male flew in from Tōkyō, Japan to find his so-called girlfriend who ran away from him. Walking down a sidewalk of Paris, the male finally stumbled upon his so-called girlfriend waiting in front of the doors with one of the Sailor Guardians. He was about to walk across the street to her, but a blonde teenage boy walked up to the duo before doing an action that made the male see red. Said blonde teenager grabbed his so-called girlfriend's hand and kissed her cheek. Glaring angrily at the couple and the nonchalant Sailor Guardian, the male walked back the way he came from with a clenched fist. "What was Usako thinking," questioned the male, "We're meant to be together! She's not supposed to be with that guy at all! She's supposed to rule with me!"

The male was still grumbling, unaware that he was attracting attention… a very evil attention by Paris' super villain, Hawk Moth. Hawk Moth, on his part, could feel the jealousy in this male and sent out an akuma. The akuma flew out of the window, as usual, and flew right into the male's shades. Said male had the same butterfly-shaped light mask that appeared on the Sailor Guardian a few weeks ago. "Jealos," said Hawk Moth through the akuma, "I am Hawk Moth. I will grant you the powers to have the one you love. All you have to do give me Ladybug and Cat Noir's Miraculous."

"Jealos," questioned the male, "That's a stupid name."

"It is not," argued Hawk Moth, "Even if it is, what kind of name would YOU want to be called?"

"Call me the Moonless Knight," said the male.

"Fine," growled Hawk Moth, "Just get me those Miraculous!"

"Will do, Hawk Moth," said the male with a smirk as dark energy circled around him.

- With The Group –

"So, what's today's agenda," questioned Hotaru.

It was afterschool that everyone was gathered at the bottom of the stairs to the entrance. Adrien had his arm around Serenity, not noticing what that was doing to Marinette's poor heart. Alya was there to comfort Marinette while looking at the assembled group. If a fortune teller told the group that they would be hanging out with Chloé of all people, she would have laughed in his/her face before walking off. Alya, however, saw that Chloé was actually NICE once she dropped the bratty attitude. Chloé also apologized for her behavior to the class, along with how her actions akumatized her classmates. Now, Chloé and Sabrina were part of their group, along with Serenity and Hotaru. "How about we head to our house," said Hotaru, "That way we can play some games and get to know each other better?"

"That's a great idea, 'Taru-chan," said a happy Serenity.

"I'm down," said Nino.

"Father would let me," said a pondering Adrien.

"Of course, Adrikins," said Chloé, "After all, your father knows your mother's last wishes. looks at the Senshi Count me in, too!"

"Sounds like fun," said Marinette with a forced grin.

"Let's go, girl," said Alya, "I want to see who Hotaru and Serenity lives with."

As the group agreed to go to Hotaru and Serenity's house, they never noticed the evil energy in the air. Hotaru, of course, was near Serenity because she felt that something wrong was going to happen very soon. Chloé stayed close to Adrien's other side as the group walked down the sidewalk towards Hotaru and Serenity's house. She too felt that something wrong was going to go down. Those bad vibes Chloé and Hotaru had came true once the group crossed the street towards the park to get to the Senshi's house. A black lightning snapped right in front of Adrien, halting everyone's movement. Serenity looked at where Adrien was about to step, but she gasped loudly when she saw what it was. Hotaru narrowed her eyes as she stood in front of her hime and Adrien, unconsciously taking out her henshin (transformation) pen. In front of them was… "Is that a black rose," questioned Nino.

"Black rose," questioned Adrien as he narrowed his eyes in suspicion.

"Who would be using black roses," questioned Alya.

"It seems as whoever did it probably left," questioned Marinette.

"Let's get to our house," said Hotaru, "We'll be safe there."

"Safe," questioned Sabrina, "From what?"

"From me," said a male voice.

The group swirled their eyes upward to where they heard the voice. There, Serenity paled considerably as she stood behind Adrien, Adrien clenching his hand where his transformation ring was. Hotaru surprised Nino, Alya, Sabrina, and Marinette by pulling out a glaive from out of nowhere. Hotaru ignored the surprised looks the three showed her as she stood slightly in front but next to Adrien. She pointed the glaive up to the male and glared. Chloé was surprised that Hotaru would show Sabrina and the other three her glaive, but she stood in front of Serenity to hide her much better from the male. The male in question was wearing traditional Middle Eastern style clothing that was all black, a black mask, a brown sash, and a hilt that housed a sword. "Who are you supposed to be," questioned Alya.

"I am the Moonless Knight," said the male, "And I have come to claim what is rightfully mine!"

"Yours," questioned Marinette.

"Her," said the male as he pointed straight at the hiding Serenity.

"I am never yours, Mamoru," yelled out a pale Serenity who surprised the group with her proclamation and knowledge of the male, "Now, leave me alone!"

"Usako," said the now known male, "You have always been mine. This blonde little boy is just messing with your mind."

"Little boy," exclaimed an offended Adrien.

"Now, come with me, Usako," said Mamoru who ignored Adrien, "I will bring you back to my side with this new power I have!"

"New power," questioned Chloé in trepidation.

"Hai," said Mamoru, "New power from my new ally, Hawk Moth!"

The group looked at Mamoru with surprised horror. Hawk Moth, they knew, was the one who akumatized people because of their strong emotions. Looking at Mamoru, they realized that he was the newest akumatized person. Hotaru surprised everyone, except for Chloé, Adrien, and Serenity, by stepping forward with her glaive. They could see Mamoru glaring from behind his black mask as he looked at the deadly glaive. "Everyone," said Hotaru, "Run while I hold him off."

"Are you crazy," exclaimed Alya.

"No," said Hotaru, "However, I have dealt with him before in Japan. I know his tricks, and you do not. looks at the group with a glare Now! Go!"

"But," started Serenity.

"Go," yelled out Hotaru before rushing to swipe at Mamoru.

The group looked on helplessly before doing what Hotaru wanted. While rushing, the group actually split up because they really did not want this Moonless Knight, this Mamoru, to come after them. Chloé and Adrien have a different idea. To protect Serenity just in case Hotaru failed, the childhood friends stayed together with Serenity The three ran until they ducked into a random building. Within the building, the three caught their breath before Adrien and Chloé saw Serenity sunk down to her knees. "Serenity," questioned Adrien.

"Why can't he just leave me alone," questioned Serenity with a sob.

"Don't cry, Serenity," said Adrien as he sat next to Serenity and pulled her in.

"Demo, that ahō (blockhead) can't take a no for an answer and followed me here," said Serenity with tears streaming down her face.

"Who exactly is he," questioned Chloé.

"Remember the story about the Silver Millennium," questioned Serenity back.

"Yeah," said the two.

"He is the reincarnated Prince Endymion of Earth and Tuxedo Kamen," said Serenity.

"But, how did Hawk Moth know that he was a knight," questioned Adrien.

"I don't think he does," said Chloé, "This Mamoru might have made that name for himself. He was probably called something else."

Serenity sighed sadly as she cuddled against Adrien for comfort. She knew that she needed to go out there to deal with Mamoru because with the powers of the Golden Crystal at his disposal, along with Hawk Moth's power, Mamoru will be hard to deal with. Adrien, on his part, was angry at how this day was almost going to end. This guy didn't take a hint when his beloved told this Mamoru guy no. He also didn't like how Serenity looked… helpless and small. Standing up with Serenity in his arms, he gave Serenity to Chloé so she could comfort Serenity before trying to march out of the building to a secluded area to transform. Adrien, however, was stopped by Chloé of all people. "Where are YOU going, Adrikins," questioned Chloé.

"I am going to stop that guy," said Adrien.

"How," asked Chloé before sarcastically saying, "Pun him to death?"

"No," said Adrien as he flushed slightly, "But, I have something that can probably take this guy down."

"Like what," questioned Chloé as Serenity stayed silent, "You know, only Miraculous holders can stand up against an akumatized person."

"Well," said Adrien who was weighing the pros and cons of telling Serenity and Chloé, "If I tell you, you promise NOT to tell?"

"Who are you thinking we are," said an angry Chloé, "Lila? Kagami?"

"No," said Adrien while Plagg was muttering in one of his ears about what he was doing.

With expectant looks, Adrien sighed before fishing something black out of his hair. Said black thing was squirming to get out of Adrien's hold and hide again from the two girls. Adrien wouldn't have none of that as he held his Kwami in both hands before showing the two girls. Chloé gasped out loud that it was a Kwami while Serenity was cooing at how cute the Kwami looked. Adrien looked sheepish as a glare from his Kwami, Plagg, came his way. "What were you thinking, Adrien," cried out Plagg.

"Plagg," said Adrien, "I think it was time that I stopped hiding from my two best friends. Besides looks at Serenity One of them confessed first about her secret identity. It's just the right thing to do."

"Though," piped up Serenity, "I'm sure Setsuna already knew that Adrien was a Miraculous holder."

"Yeah, yeah," said Plagg with a pout, "Now what, lover boy?"

"Plagg," said Adrien, "Claws out!"

With that, Chloé and Serenity saw Adrien transform. Adrien, on his part, was self-conscious about how he looked after the transformation stopped. He now wore a textured black skin-tight cat suit with metal details, black cat ears, a black mask to cover his face, and a black ring with a bright green paw print on its face. Serenity was blushing because she thought Adrien looked very hot in his outfit while Chloé was gaping at Adrien. "You," started Chloé.

"Chloé," questioned Adrien.

"You're Cat Noir," yelled out Chloé in Adrien's face.

"Shh~," shushed Adrien, "Someone might hear."

"I can't believe my best friend is Cat Noir and never told me," ranted out Chloé.

"Uh, Chloé," questioned Adrien, "Can we finish this after I take care of the akumatized Mamoru?"

"You can't," said Serenity.

"What do you mean," questioned Adrien who looked at Serenity.

"I am going with you," said Serenity, "Because I have the powers to combat his Golden Crystal."

"You mean he has the Golden Crystal at his disposal too," asked Adrien in exasperation.

"He is the Earth Prince," said Serenity with a deadpan look, "Of course, he'll have those powers too."

"Then, how do we defeat him," questioned Adrien.

"Chloé," said Serenity with a smirk, "How would you and Adrien like to become Senshi?"

- With Hotaru –

"Silence Glaive Surprise," called out Hotaru.

When the others left, Hotaru fought against Mamoru until she sensed no one around. Hotaru, also not wanting to transform in front of Mamoru, ran as fast as she could before ducking into a dark alley. She called out her transformation phrase before transforming into her alter-ego… Sailor Saturn. Jumping to the roof of the building she was in, Hotaru spotted Mamoru's frustrated face as he tried to find her hime or her. Hotaru then surprised Mamoru by slamming one of her purple boots to the back of his head. Mamoru fell down on Paris' busy street before growling. Hotaru had to use her Silence Wall when Mamoru threw a blackish gold energy at her. She huffed as Mamoru dodged her Silence Glaive Surprise attack before jumping out of the way of the roses. "Tell me where your hime is, Saturn," growled Mamoru.

"How about I stick my Glaive into your body and you die slowly," growled back Hotaru, "I will NEVER tell you where my hime is!"

"Then, suffer," said Mamoru as another blackish gold energy was shot at her before…

"Starlight Flash," called out a female voice.

"Nani," shouted Mamoru as he looked up.

On top of a building, there were two Sailor Senshi. One Sailor Senshi was recognizable as Eternal Sailor Moon. However, the other one was not. That one was wearing a white and dark blue Sailor outfit while the ascents were light yellow. The two Sailor Senshi jumped down from the building and stood next to Hotaru as Sailor Saturn. Hotaru, however, looked confused to the newest member before looking at a smirking Serenity. "Hime," questioned Hotaru.

"Saturn," said Serenity, "Meet Sailor Star, the newest addition to the Sailor Senshi."

"Sailor Star," questioned Hotaru.

"Hai," said Serenity, "Demo, she'll reveal herself to you later. Right now, we are to distract Mamoru while Cat Noir and Ladybug comes."

"Cat Noir better be fast to find Ladybug," grumbled Star as she glared hatefully at Mamoru, "This guy either needs to be purified or dusted like the Youma you all had to fight."

"How does she," questioned Hotaru.

"No time, Saturn," said Serenity as she jumped away from the roses.

As this was going on, another building held a female wearing a red superhero jumpsuit covered in black spots and with a black collar/turtleneck. This female didn't know what was going on, but to her, it seemed like there were four akumatized people, but three of them were fighting the first one she encountered with her friends. Thinking on what to do, she didn't realize that Cat Noir was behind her and looking a bit different. "Hey, Wonderbug," said Adrien from behind.

"Cat," started the female, Ladybug, before pausing with a question, "Noir?"

"Do you like," questioned Adrien who was playing with the gold ascents to his costume, "The Sailor Senshi, Sailor Moon, explained that this guy has Hawk Moth AND his own powers."

"What," yelped Ladybug.

"Yup," said Adrien with a cat grin, "So, to help the Sailor Senshi, who are wearing the short skirts by the way, out, Sailor Moon gave me some power ups of my own."

"So, the female in the short skirts are good," questioned Ladybug.

"That's right, Bugaboo," said Adrien with a smile.

"Then, let's weaken this guy first before we use our powers," said Ladybug who held her yo-yo out.

"Lead the way, Bug Eyes," said Adrien with a bow.

Ladybug swung her yo-yo and soar through the air before kicking the akumatized male down. The Sailor Senshi smiled in relief. They didn't know if the damage from their magical attacks will be gone by Ladybug's magic, but they hoped as they squared their shoulders. Adrien vaulted over before landing a punch at the male. He knew that Ladybug and he had to find the akuma, but on how to do that was the problem. The attack against the akumatized Mamoru went on. It seemed like the Sailor Senshi and Paris' superheroes couldn't weaken Mamoru. Mamoru, on his part, was smartly using the akuma to send out energy attacks while the Golden Crystal at his disposal healed his wounds. He glared, though, when he saw the Cat Noir helping his girl up and holding her hand. He could see Serenity smiling at Cat Noir and couldn't stand it. Sending a golden blast towards the couple, only Serenity saw the blast. She pushed Cat Noir out of the way until she was the only one engulfed by the blast. "Hime," shouted Hotaru.

"Moon," shouted Ladybug and Star.

"No," yelled out Cat Noir in despair.

"That's what she gets for standing in the way," said Mamoru, "But since she is down, it's easy to destroy you before I rule the world with her by my side!"

"I won't let you," yelled out Cat Noir.

Due to the anger he felt, Cat Noir rushed in to fight Mamoru. Mamoru could see that Cat Noir was using his staff as a sword and drew his own sword out. As the two dueled, Ladybug, Sailor Star, and Sailor Saturn rushed to the down Sailor Moon. Sailor Star looked really angry as well as she turned to look at the fighting men. Using her new powers to create her own spear, Sailor Star leapt into the fray to help Cat Noir take down Mamoru. Sailor Saturn started to glow lavender before placing her glowing hands on Sailor Moon as Ladybug looked helpless. "How is she," questioned Ladybug.

"She's unconscious," said Hotaru with a glare, "I wish that she wouldn't have done that… again."

"Will she be alright," questioned Ladybug gently as she winced at the again part.

"She will be," said Hotaru as the glow subsided.

"Shall I use my powers now," questioned Ladybug.

"Yes," said Hotaru, "We should know what can help to bring Mamoru down."

"Okay," said Ladybug before throwing her yo-yo up and shouting, "Lucky charm!"

As the yo-yo spun, it spat out an object that the Sailor Senshi knew very well. Ladybug was now holding onto a red crescent moon wand with black spots. There was also something that could fit in the center of said wand. Ladybug looked surprised by what her Lucky Charm produced, but Hotaru knew what the magic wanted. Wincing inwardly, Hotaru gently looked at her unconscious hime. "I… I don't know what to do with this," said Ladybug as she frantically looked around her.

"I do," said Hotaru.

"You do," questioned Ladybug.

"It seems as though fate wants my hime to be the one to finish this," said Hotaru.

"Huh," questioned Ladybug before…

"S-Saturn," groaned out Serenity.

"Hime," said Hotaru who gently lifted Serenity to a sitting position, "Daijōbu?"

"Un," nodded Serenity, "Just slightly. And why do you look worry?"

"Because to finish this," said Hotaru, "You have to use the crescent moon wand."

"Eh," questioned Serenity.

Serenity, as Sailor Moon, looked up to see Ladybug holding a replica of her crescent moon wand. Apparently, the only way to stop Mamoru was to use her powers with the combined powers of her Sailor Senshi. She was just glad for her foresight to grant Adrien some powers. This was going to make her pass out for a week. Serenity slowly got up from her sitting position with Hotaru's help before gesturing for Ladybug to hand over the wand. Ladybug looked skeptical and worry, but she did as was told. Ladybug was surprised to see Serenity glow before a small silver crystal appeared. She was more surprised when Serenity grabbed the small silver crystal and placed it snuggly in the center of the wand. Steading herself, she waited until she heard Hotaru yell at the two Senshi to stand back. She did, however, hear Cat Noir yell out Cataclysm before seeing him destroy Mamoru's sword. "Cat Noir," called out Hotaru, "Sailor Star! Move!"

"Moon Healing Escalation," called out Serenity.

As Cat Noir and Sailor Star jumped to land behind Serenity and next to Hotaru and Ladybug, a trail of silver glitter and mist went around Serenity before producing light. That light became rays of light and balls of white energy before going towards Mamoru at a fast pace. Mamoru didn't have enough time to get out of the way or produce the Golden Crystal before the light washed over him. However, the light still wasn't strong enough to fully heal Mamoru due to his resistance until Hotaru, Sailor Star, and, to Ladybug's surprise, Cat Noir shouted a phrase that had lavender, light yellow, and bluish pink lights hit the light and amplifying the affects. Shouting Refresh, the dark energy faded away from Mamoru and produced the akuma. Ladybug quickly captured the akuma in her yo-yo before releasing a white butterfly. "Ladybug," said Hotaru who gave the crescent wand back without the silver crystal, "Can you take care of everything else here?"

"Of course," said Ladybug, "What about Sailor Moon?"

"We'll take care of her ourselves," said Sailor Star.

"I should skedaddle too," said Adrien, "Until next time, Bugaboo."

- At The Outers' House –

"Chloé," asked a shocked Hotaru, "Adrien?"

Once the four retreated and met up at the Outers' house, Adrien let his transformation of Cat Noir fade away. Plagg was not far behind to reappear and jump into Adrien's pocket for his favorite cheese, Camembert. Hotaru, Serenity, and Sailor Star's henshin disappeared as well to reveal Sailor Star was Chloé all along. Hotaru looked at Serenity's friends in shock until she saw Serenity sway from the energy use. Adrien was quick to catch Serenity and hold her bridal style so she wouldn't have to stand anymore. "Let's go in and we'll talk," said Chloé.

"You bet your," started an angry Haruka who started the four.

"Haruka," shouted Michiru.

"Demo, Michi," said Haruka, "Just look at koneko! She's injured AND exhausted!"

"That doesn't mean," started Michiru.

"Just come in, you all," said Setsuna while ignoring her fellow Outers, "We have a lot to talk about."

"Hai/Yes, Setsuna/mama," said the four.


AN: This is the LAST time I am going to do a one shot for this crossover. For! I have my other fanfic stories to write too. (╥ω╥) Anyways, I combined the akumatized Mamoru with the outfit for Moonlight Knight and Prince Endymion. (⌒_⌒;) I also had to throw in that Mamoru is different since he IS a reincarnated person with powers, especially with the Golden Crystal bit. ┐(︶▽︶)┌ And you also know that Adrien is going to be protective of Serenity in the end, too. That should be a given. (¬ ¬) It should also be a given that Chloé would want to help too to protect Serenity as well. (↼_↼) Anyways, happy reading and see ya whenever in my other fanfics! |ω・)ノ
