****Author's Note****

Me: Is it just me, or are these author notes becoming like "My life with the PPGZ"?

Momoko: Yeah. Pretty much.

Me: Okay. Since this chapter deals with the good and evil side of a person, I paid Kaoru, Miyako, and the twins do the disclaimer as characters from Star Wars.

Danielle: *walks in dressed as Princess Leia* Len doesn't own Powerpuff Girls Z, the Powerpunk Girls, Star Wars, or any reference you may find.

Daniel: *walks in dressed as Luke Skywalker* He just owns the OC's and the plot of this fanfic.

Kaoru: *walks in dressed as Darth Vader* *breathes* Please review. It is your destiny! Any flames will be reported to the emperor and the offender shall be brought before him. *breathes*

Miyako: *walks in dressed as Emperor Palpatine* *cute smile* Now sit back, relax, and enjoy the show!

Momoko: Why are Kaoru and Miyako dressed as Darth Vader and the Emperor?

Me: Leia and Luke are twins, so it makes sense to let the twins play the twins. Besides, you've seen Kaoru angry a lot of times. Now let's get this show started!

Yin and Yang

"We're back!" the team yelled as they flew back to the lab. After transforming back, the team took the time left in their day to do what they wanted, except for Daniel. While Miyako was reading fashion magazines, Kaoru was shouting at the TV screen for her team to win, and Danielle was helping Professors Tinaxo and Utonium, Daniel was stuck translating the comics he brought.

"What does this guy say?" Momoko asked him

"Do you even pay attention to English class, Momoko?" Daniel asked back

"Kind of."

"The hero just found out that the bad guy he's fighting is an evil twin robot. That would be pretty weird if we had evil twins, though. Considering the fact that we're superheroes, it may be possible." Daniel said, smiling. A huge sweat drop formed on the back of their heads. They were clearly thinking of the Rowdyruff Boys. "I mean the twin looks exactly like you, with the exact same DNA and everything." Daniel clarified. "By the way, I won some tickets to the amusement park from a radio show. You guys want to come?"

"You bet!" everyone else responded

The next day...

The girls and the twins were at the amusement park. Inside, there was a man with the yin-yang symbol on his chest. "Once I get rid of those Powerpuffs, then I'll have the city! No, wait, why would I want to hurt them? They didn't do anything to me. Wait, what?" The man fell to his knees "I...must...destroy...no...I...mustn't...yes...I...will...ack!" all of a sudden, a dark aura surrounded him, when he held his aching head. He got up and looked around, searching for the girls.

Meanwhile...

Momoko had her head over a garbage can.

"I told you not to eat that candy before you went on the roller coaster." Miyako scolded, looking very disappointed at the leader.

"But I couldn't resist." Momoko retorted as she stood up, wiping her mouth. "What about Danielle? She finished a burger before we went on!"

"She didn't throw up. Besides, she and her brother are competing against each other in the arcade."

"Where's Kaoru?"

"With the twins. She's keeping score."

With the twins, Kaoru was watching them at the arcade. So far, the score in all the games was tied. From racing games to fighting games, Daniel and Danielle were an even match. When she looked away from the screen and outside, she saw a man with a yin-yang symbol on his chest angrily throwing passerby, knocking out the adults, and flipping over food stalls. Kaoru nudged the twins with her elbows to get their attention and pointed towards the man outside.

"What is he doing?" asked Danielle.

"Asking for trouble, sis." answered Daniel.

"Let's take him out!" Kaoru said as they all reached their compacts.

Powered Buttercup!

Speedy Bullet!

Dive Bomber!

"Powerpuffs, ready to go!" Bomber and Bullet shouted as they took off to stop the madman. Their transormation caused Momoko's and Miyako's compacts to go off as well.

"Looks like the others found trouble!" Miyako called.

"We've got to help them!" Momoko said as ther ran into the bathroom to transform.

Hyper Blossom!

Rolling Bubbles!

"Let's go!" Blossom shouted as the two Powerpuffs blasted off to where the others were. As the Puffs regrouped, the man with the yin-yang symbol called out to them.

"Powerpuff Girls Z! At long last! You shall meet your maker...n-no. Please, girls, help m-me. Shut up, fool! I'll destroy them! N-No! D-Don't do it!" The girls and the twins looked at the man in confusion, who looks like he was arguing with himself. "Yin-Yang Blast!" he called, shoogting a beam from the symbol on his chest, hitting each of the Powerpuffs square in the chest.

"What's going on?" Blossom called as she felt an extreme amount of pain in her abdomen. All the others felt the same way. All of a sudden, a head emerged from each of their torso, then a body, and then it flew off. The pain was gone, but there were five adversaries in front of them.

Powerpunk Z!

All of the Powerpuffs turned to look at who shouted that intro. They saw four girls and a boy. They looked like each of the Powerpuffs, but their colors and styles were darker.

"You have got to be kidding me!" Bullet shouted. "That beam gave us evil twins!"

"Wait a minute, why is my evil twin a gangster rapper?" Bomber complained, pointing at Dark Bomber, who had baggy jeans, a hooded jacket, a baseball cap, and a gold chain around his neck. "Aren't evil twins supposed to look like you right down to the clothing except for one thing?"

"I don't see what yo problem is, boy, but I'm gonna bust your..."

Me: Language, please.

"Fine. I'm gonna beat you down!" Dark Bomber shouted. All ten took out their weapons. As Bomber and Dark Bomber started throwing marbles, the rest of the Puffs flew off in different directions. Blossom faced off against her evil twin, but their yo-yos got tangled, so they had to resort to hand-to-hand combat.

"Heh. You're weak. I can blast you from here to the moon in one shot!" Dark Blossom called as she landed a punch to Blossom's face.

"You and what army?" Blossom shot back as she roundhouse-kicked Dark Blossom in the torso before throwing her into a building. Dark Blossom got up, unscathed.

"Bring it on, runt!" Dark Blossom called, charging strait for Blossom. Bubbles, on the other hand, was in a stalemate with Dark Bubbles.

Bubble Champagne!

"Is that all you've got, you little brat?" Bubbles' attack hit, but it didn't hurt at all. Dark Bubbles charged in with the sharp end of her bubble wand, ready to impale her good counterpart. Instead, Bubbles was just sent to the wall of a building, cushioned by a bubble she made. Seeing that blowing bubbles aren't enough to defeat the other, they decided to fight using their bubble wands as staffs, like Buttercup and her evil twin were doing with their hammers.

"Bring it on. I can take you out any time!" Buttercup shouted at her evil double, swinging her hammer, scoring a hit over the head.

"I've met mosquitoes that hurt more than you, wimp!" Dark Buttercup shouted as she brought her hammer to level with her good twin. As the two hammered it out, two flashes of yellow light collided rapidly. Dark Bullet was fencing with Bullet, trying to bring their paper sword to each other's throats. Each time they crossed blades, a spark of yellow energy forced them apart again.

Marble Stun!

Bomber managed to score a hit with a marble and now Dark Bomber can't move. Bomber then proceeded to use that same technique on the other dark doubles, bringing them to the ground, paralyzed.

"Nice job, Bomber. How do we get rid of these guys?" Blossom asked.

"Beat the guy who shot that beam at us." Buttercup responded. However, the man who shot the beam was long gone and in the middle of Tokyo City by now. Blossom opened up her compact to contact the professors back at the lab.

"We've got major trouble, professors! This guy made evil clones of us! Can Peach track him?"

"Ah, Blossom. Professor Utonium is asleep right now. Peach told me about what happened." Professor Tinaxo replied. "He is known as Yin, a famous Chinese Taoist. He came to Japan last month and must've gotten hit by a black light. An unusual man, he is. At one moment, his personality can be light and happy, and in a second can be dark and angry. The black light must have increased his dark personality until it overtook his mind. Quickly, bring him to the lab so we can cure him! I'm sending his location to my children, so follow them."

"Bullet?" Blossom asked her yellow friend, closing her compact.

"Got it!" Bullet looked at the information through her sunglasses. She and her twin knew where Yin was going and how to intercept his movement. "Follow us and stay close!" Bullet and Bomber took to the skies heading northwest.

"We've got to hurry! The stun effect on our counterparts only works for five minutes!" Bomber shouted, causing Bullet to grab everyone and break the sound barrier to land at the specified location. Bomber made sure the area was clear and laid a few gas marbles on the sidewalk before going into hiding. Yin walked past the trap, activating it, putting him to sleep instantly.

"Okay. Let's take this guy back to the lab and cure him!" Buttercup shouted as she slung Yin over her shoulder. All of a sudden, five figures appeared in the sky and dove toward the Puffs.

"They're back!" yelled Bubbles. The evil doubles dove out of the sky to attack their good counterparts.

"Take him back to the lab. We'll take care of these guys." The girls said as they readied their weapons. Daniel took Yin off Buttercup's shoulder and put the still sleeping Chinese Taoist on his shoulder. As Bomber took off for the lab, Dark Bomber followed in pursuit.

"Give the boss back! He shall lead us to bring the world into the darkness, boy!" Dark Bomber called out.

"Says the rapper wanna-be!" retorted Bomber as he threw a smoke marble, which exploded in Dark Bomber's face, allowing Bomber to escape for the lab. Meanwhile, the girls were winning against their doubles. Blossom stole Dark Blossom's yo-yo and tied her up with them, taking that threat out. Bubbles made some sticky bubbles and subdued Dark Bubbles, gluing her to the ground. Buttercup managed to score a critical hit with her hammer, knocking out her evil twin. Bullet had her swords crossed, the blades touching Dark Bullet's throat, threatening to cut her head off scissors-style. At that moment, all of the doubles started to glow with a white light before being reduced to a small ball of dark light. The light rose and started to circle, before dispersing and entering the bodies of each of the girls.

"What just happened?" asked Buttercup, who seemed confused by this turn of events. After realizing their victory, the four flew off to where Bomber was. At the lab, Bomber put the sleeping Yin onto the table with his father manning the transformation ray. Before the button could be pressed, Dark Bomber broke through the window and charged at the table, attempting to free the sleeping man. At the last second, Professor Tinaxo flipped the switch, turning on the transformation ray. Yin started to glow with a white light, and the yin-yang symbol on his chest was gone. Dark Bomber stopped in midair, started to glow, and turned into a small dark light, which entered Bomber's body. As the light entered Bomber, the rest of the Puffs entered the room.

"Did everything go okay?" Bubbles asked as she noticed the broken glass. Yin began to wake up, making the girls reach for their weapons, that is, until they noticed that the symbol on his chest was gone.

"Thank you so much, Powerpuffs. Ever since that black light hit me, I have been unable to control the yin side. I am grateful." Yin said, bowing lightly.

"What was that beam you shot at us?" Blossom asked, hoping to get an honest answer.

"That beam, I believe, was meant to extract your yin from your yang, separating good and evil halves. For everyone with good inside them, there is also evil that they have to control. Remember this before I depart for China: No matter where you go, where good exists, evil shall as well, for there can be no day without night, no darkness without light, and no victory without defeat. Heed these words, and you shall live a good life." Yin stood up and walked out of the lab, going home to China.

"Words to live by, aren't they brother?" Bullet asked

"Indeed, sis." Bomber responded. As they all changed back, they spent another bored day at the lab, doing anything from chores to just watching Daniel argue with Momoko about which superhero can beat which in a fair fight.

Me: Not too bad for a hero versus self conflict, right?

Momoko: A little tough, though. How is it that we couldn't beat them the first time, but we beat them the second time?

Me: *reads instruction manual* Apparently, Bomber's stun marbles have a side effect. After recovering from paralysis, the victim may suffer from moderate to severe muscle cramps or spasms in random locations. You try fighting with one of those and see if you win.

Momoko: Point taken.

Me: Next time, a new student transfers into the heroes' school. Later, in an incident involving a banana cream pie, wrestling, and a game of blackjack, the Puffs have to deal with an angry Himeko. Stay tuned and please review!
