Hi, everyone. This is the first chapter of Hero meets Heroines. Without any delay, let the story BEGIN!

Chapter 1: New world, new hero.

It was night time in the city of Townsville. The streets were partially quiet and no sign of trouble that could be seen or detected. It was one of those normal nights that the city didn't have a monster attacking or a villain trying to take over the world. However, this night was different than any other, though no one would notice.

Above the skies, a red humanoid manta alien flew. The people below failed to notice and that was what the alien wanted. To others, the alien was another monster, but this one was special. Though it looked like an alien, it had a green and black hourglass on its chest.

The alien continuously flew through the air, saying his thoughts, "Well here we go again. No place to stay, meaning no place to sleep. Good thing no one can see me cause the last thing I need right now is battle another hero." The alien came to an isolated alley and touched down. In a flash of light, standing in his place was a brown haired teen, "Now to save the world."

At that same time, an alarm went off in a lab located in a town far from Townsville. A boy in his teens, wearing a lab coat and wearing glasses snapped his fingers and the alarms went off.

"Computer, what's the problem at hand?" The teen asked.

A voice from the lab, sounding female and computer like answered, "A strange energy anomaly has been detected within Townsville. Just an hour ago, a bigger detection of dimensional entry was detected."

The teen remained silent, his arm holding his chin as he thought. He walked to a large screen and pressed a button, which then displayed a map with two dots. The first dot was smaller while the other was bigger, but distant away from the first. The teen fixed his glasses in and said, "Your detection is indeed correct computer, but the question is who they are? I must investigate."

Morning came up, filling the town with light and life. The normal routine for the town began as people did their normal activities without any trouble. From the skies, three streaks of light in red, blue and green flew above. The people below waved at them, cheering and smiling. The source of the light was actually three middle school girls, at the age of thirteen.

The first girl wore mostly red. She had pink eyes and long red hair that reached her waist. She wore a red shirt which showed her midriff, a red skirt with black stripes and long white socks with black shoes.

Next was her sister in blue. Unlike the first girl, she has blue skies eyes and blond pigtail hair. She wears a blue dress, resembling her former clothing when she was little. She also wore a white scarf around her neck and a blue Paris beanie. Like her sister, she wore a white socks and black shoes.

Lastly was their sister with green eyes. Unlike her other sisters, her clothing had a mix of dark. She wore black jeans with small green stripes, along with a black shirt that showed her midriff. Though she wore too much black, she still kept her color, for example her green eyes, green gloves and a green lightning bolt at the middle of her black shirt.

Over the years, the girls have achieved so much since their creation. Their battles over evil has become known to the extent that aliens were aware and made sure to never visit the town. However, that couldn't be said for the normal villains and monsters that attacked every chance they got. The Powerpuff girls made sure the villains never succeed and still kept themselves pure in heart as they did well.

While they flew through the air, the girl in green spoke, "Men am I glad the weekends are back, every day its school this and school that."

"Relax, Buttercup." replied the red haired, "School is actually good for your knowledge. You can't always think brawl is more than smarts every time. The world is filled with its fascination and…"

"You know what I just heard?" Buttercup interjected, "I heard blah, blah, blah, something about knowledge and brawl beats smarts. Face it, Blossom we're the Powerpuff girls and we can beat anything that comes our way."

Blossom only response was a small growl. It didn't seem to threaten Buttercup, but the blond of the girls intervened, "Blossom is right, Buttercup. I love the arts classes."

"Blech." Buttercup made a puke face, "You two make me want to puke. I just hope something big comes so I can beat it up."

"One of these days, Buttercup something powerful might come along and you won't be smirking." Blossom said.

However, Blossom's words only made her grin, "Oh, that'll be fun."

*****************************************************(LINE BREAK)********************************************

Meanwhile, across Townsville…

A black fast car drove through the street in a hurry as police cars chased them. Within the car, armed men wearing mask were trying to elude the police cars. So far the police were still on their tail and if nothing was done they would be caught. However, these arm robbers weren't going to go down easily. Time was running out and if they didn't hurry the Powerpuff girls might get them.

From the back, a lone robber brought half his body out, holding a bazooka, "Eat this you stupid coopers." No sooner, he pulled the trigger and fired a big missile. It flew straight to a police vehicle right behind them and hit the tire, causing the vehicle to tumble. Luckily, the officer inside wasn't too bad, but some police cars stopped for the injured cop while three others gave chase.

The lone vehicle put his body back him and turned to the leader, who sat at the front passenger seat, "The cops are still after us, what we do now? There's no way I'm going back to the slammers."

"Shut up!" The leader scolded, "No one is going to jail and those cops won't know what hit them."

The leader took a rifle laser gun and brought half his body out. He gripped the gun, narrowing his eyes as he chose a good target. Once he got a target, he shot a nearby lamp post that they passed. The lamp post was hit and fell, hitting one of the police cars, thereby obstructing the other behind. The only vehicle unaffected continued to give chase.

"Oh no, you won't." The leader gritted his teeth. He chose another target and fired. This time it hit the ground, creating a large hole. The lone police car was driving too fast that it hit the hole, causing to lose control and fall underside down. The leader smiled at this and sat back in, "Now that's how you deal with them."

Unfortunately, up ahead of them a woman was walking with her baby. The robbers noticed when they were getting closer, but none of them made a move to stop. If anything they increased their speed. The woman heard the sound of the car coming and gasps. There was no way she could escape…

Suddenly, a green insect creature, resembling a humanoid grasshopper, landed in front of her and picked her up with her holding her baby. The woman didn't have much to react before the creature jumped away just before the car could hit. The creature landed on the sideway and dropped her and her baby.

"Thank you." The woman smiled at him, though taken back a bit, "Who are you?"

The creature, very well known as an alien, smirked, "Call me Crashhopper."

With that said Crashopper jumped off, while heading to the bad guys. While they rejoice about their escape it soon ended as the car shook when something landed on the roof.

"What was that?!" One of them asked.

"I don't know, kill it!" The leader commanded, already holding his laser rifle. The robbers, minus the driver, brought out their weapons and opened fire at the roof. The thing on the roof leapt off before getting killed and landed in front of them, standing in readiness. The thing was Crashhopper.

The driver nearly freaked when his eyes fell on the alien in front of them, "What is that thing?!"

"I don't know, just squashed it!" The leader yelled angrily.

As ordered, the driver increased his speed to full. Crashhopper only grin smirked and got into a stance to jump at them, "So it's squash the alien bug day, huh? Well let me show you that this bug is an exception."

The car moved full speed ahead, but Crashhopper was first. He shot himself straight at them, his horn straight, and hit the front of the car, making it come to a halt. The car deployed its airbag, saving the ones in front from hitting the glass. However, that couldn't be said about the ones at the back, unconscious.

The leader snarled through his teeth, cursing about his failed operation. He immediately got out of the car and so did the driver. He scowled on the first thing he saw, which was Crashhopper, "You lousy bug, I'll make sure you're squashed for this!"

"Yeah, yeah, yeah, just get to the part you start shooting." Crashhopper taunted at him.

The leader didn't respond, but instead angrily shot a laser from his rifle. Before it could get him, Crashhopper jumped high up to avoid the blast. He then did a front flip before coming down and stomped down on the leader. Done with the leader, he smirked and turned to the driver, who held a small gun, "You want to do this the easy way or the hard way? And I hope for the latter."

The driver held the gun, shaking it rapidly with fire as he directed it at the alien. He seems hesitate as he tried to pull the trigger while trying to overcome his fear. Finally, he couldn't take it anymore and hit the gun to his head and fell unconscious on the ground.

"Well that fixed that." Crashhopper said proudly. He soon got caught off with cheering from bystanders. The young hero smiled at them and waved, "Thank you, it was all in a day's work." While he waved, he noticed some strange colors heading his way, "Hmm, strange rainbow colors on a sunny day." Rather than narrowing his eyes to get a closer look, he shrugged and jump off the other way.

If Crashhopper had stayed, he would have met the Powerpuff girls. Though he didn't see them from the distance, the girls were able to see him from the sky. Once they got there, they landed on the ground as the crowd continued cheering for the hero that just left.

"What happened here?" Blossom asked, looking around the area. The people were cheering, but it wasn't for them and a car was broken down. Next to that, two robbers lay on the ground unconscious.

"I don't know, but I'm sure it's that bug thing is the reason." Buttercup replied, glaring at the distance. She enhanced her sight, making it able for her to see the distance. She found a humanoid grasshopper leaping from building to building and cocked a small grin, "I'm going after it!"

"Buttercup wait!" Blossom shouted, but it was in vain. Buttercup ignored her sister, too determined to get the humanoid grasshopper.

********************************************************(LINE BREAK)********************************************

Crashhopper leap from building to building, enjoying the jumping sensation. He didn't know why he liked it, but he could guess that it was his current alien's trait. If it weren't for the sensation, Ben would have hidden somewhere and changed back. But at the moment Ben didn't care the least. The Omnitrix was still at full power and he didn't seem bother to change.

Everything went smoothly until he heard a faint female cry getting louder. Once he heard it, he came to a sudden halt, on top of a skyscraper and looked back. The next thing he knew, someone threw herself on him and pinned him to the ground.

Finding himself in a stuck situation, Crashhopper struggled, "Hey, what's the big idea." He went numb for a second when he glance at who held him, "Wow, you're a girl."

"Of course I am; who did you think it was?" The girl said to him, "Care to explain why you ran off."

"Sorry but I don't answer like that especially from a tomboy girly girl." Crashhopper retorted and tried to struggle out of the girl's hold.

The girl snickered, "Try as much as you can, there's no way you can escape."

"Okay." Crashhopper sighed, closing his eyes. To Buttercup, he was quiet, but actually he was forming a quick plan, "Hey, what's that over there?" Crashhopper snapped his eyes open, looking over her.

Buttercup fell for it, releasing her hold on the alien. Crashhopper took the chance of distraction and sent his feet at her, sending her flying to the air. However, Buttercup came to a halt in the air and glared at him, "Hey, you tricked me!"

"Duh." Crashhopper snickered, like it was the most obvious thing, "Honestly speaking, I didn't expect that to work on a tomboy girly girl."

"WHAT DID YOU JUST CALL ME!"

Watching the fuming girl, Crashhopper took a step back in fright, "Uh oh."

Suddenly, an impact blow hit Crashhopper that he didn't see it coming. All he knew, the blow hit his stomach and shot him right off the skyscraper and making a crater in the street.

"Ow, that hurts." Crashhopper groaned. He shook off the pain from the impact, already feeling it go away. He then looked up and saw Buttercup glaring at him, "Can't we talk about this?"

All traces of anger from Butter were replaced with a grin, "Nah, then where's the fun. I've been looking for something to beat up all day."

"So I take it as a no?"

Buttercup's next response was shooting her laser beams at him. Crashhopper reacted quickly and rolled out of the way, but still got caught by the explosive impact. It forced him to tumble and roll until he came to a stop. Just as he did, Crashhopper stood up, "Okay, you want a fight then I'll give you a fight."

"Then don't disappoint me." Butttercup said, excitedly with the same grin. She charged up her laser beams and fired at him.

To avoid the blast, Crashhopper jumped backwards, avoiding its collision and impact. He then took a strong stance and jumped straight at Buttercup with his horn in front. Buttercup watched him coming, but made no move to avoid it. Instead, when it came she held the horn with one hand and threw a hard punch that knocked him down.

"Come on I don't have all day." Buttercup watched him get up.

Crashhopper responded with a groan and stood firmly. Clearly, his attack didn't work and didn't seem to work for this alien form. So instead, the bearer of the Omnitrix and took off, "Okay, new plan."

Though a bit taken back at his retreat, Buttercup followed him from behind, becoming less serious at the second. What should have been interesting was getting boring. However, she made no move to attack, but instead gave chase. Crashhopper kept going until he came to a halt at a manhole and ripped off the cover.

Buttercup halted, still hovering in the air, "What are you doing?" Crashhopper didn't answer, but jump inside the sewers. Taking it that he was running away, Buttercup flew closer to the manhole, "If that's your way of running it's a stinky one."

Through the darkness, Buttercup saw a flash of green light. She didn't know why, but then the ground began to shake. Suddenly, vines sprouted out of the street and wrap around her. It literally caught her by surprise and tied her as she came face to face with a plant alien with one eye, "Who said anything about running?" the alien formed a smirk.

Wildvine held her tightly, cutting off any oxygen. Unknown to him, Buttercup didn't need oxygen to stay conscious, though she felt the pain all over her body. She struggled for a while before throwing both her hands out, tearing through the vines.

"Surprise!" Buttercup charged her laser beams and fired. Wildvine hissed from the pain, but then Buttercup flew straight at him and threw a hard blow. Since he didn't expect it and couldn't avoid it, Wildvine was sent a few meters.

While he lay on the ground, Buttercup flew slowly to him. Wildvine didn't seem to move and she almost felt disappointed that she beat him easily. She knew better not to underestimate anyone and knew something was wrong. Her confirmation was right as Wildvine swiftly took out some black seeds and threw it at her that hit her, knocking her a few feet into the air.

The Powerpuff girl regained herself, preventing from touching the ground. She still was taken in by the seeds effects, affecting her mind in a dizzy way. Before she knew it, Wildvine shot his vine like fingers at her, trapping her in a cocoon. This time he swung her around him before throwing her to the ground

Wildvine retracted his fingers to their normality, "Had enough? I got more where they come from."

Buttercup slowly got back to her feet with her head down. She remained silent for a while before racing her eyes, revealing glowing red eyes.

"Uh Oh." Wildvine said, knowing the next outcome.

From where she stood, Buttercup began to fire laser beams at Wildvine. Each blast cut through him, but they healed swiftly. Wildvine glances at the supposed wounds and smiled stupidly at her. His smile only made the Powerpuff to growl, though in a low tone. She didn't fire any laser beams after that, since they weren't working.

Instead, Buttercup began to rub her hands together. It would seem normal until they began to spark electricity. Wildvine's eyes flew wide, already knowing her next move.

"Let's end this." She said, clutching both her fists as they charged electricity.

She pushed both her arms forward, sending the electric voltages at Wildvine. Due to his poor agility, Wildvine couldn't move much to avoid it and got hit, exploding into small pieces.

Buttercup dropped both her fists down and smiled, "This time stay down if you know what's good for you." She then turned away and pulled out her phone, "I better call the girls and tell them about this thing." However, right behind her, the scattered pieces of Wildvine began to form into. The process was quiet that she was unaware until it was too late.

"You were saying." Wildvine smirked, finally back together. Just as he finished, he swat his arm at her, sending her crashing into a car. Everything seems quiet for the next few seconds until Buttercup walked out without a scratch, "Okay…I should have seen that coming."

"Yeah, that's what they all say." Buttercup cracked her knuckles, showing the smirk on her face, "Let's see if I can't put you to your place."

Buttercup made a straight line at Wildvine and threw a punch at him. However, this time, Wildvine was prepared and went into the ground. He came out a few meters from her right, "I'll admit, but let's see you handle Kid Impervious."

Immediately, Wildvine slammed the Omnitrix symbol on his chest and became engulfed in a flash of green light. All over his body, his strength enhanced and his body shaped. He grew nine feet tall and began to grow hair all over his body. No part of his body was left out during the transformation before it was complete. When the light died, in Wildvine's place was a nine foot humanoid tiger with orange and white fur and green eyes.

"Kid Impervious!" The alien tiger shouted. However, he became wide eyed and snarled at the symbol on his chest, "Lemme tell you something, Omnitrix! Rath has gotten sick of you not working; it's not even funny anymore."

Buttercup raised an eyebrow, "Okay, so are you going to fight or not."

Rath glared at her, "Lemme tell you something tomboy girl; Rath has enough of this fight. In fact Rath is gonna show you want Rath…" He was cut off as Buttercup shot him with a laser beam that hit his shoulder. It didn't do much but he yelped, "Ow! Hey, why did you do that for?! You can't interrupt Rath when Rath is doing his thing!"

"Really cause all I heard is how dumb you are." Buttercup snickered at him.

"Okay, that's it!" Rath roared.

Like the raging tiger he was, he rushed at her in such a speed that he got Buttercup by a hard punch. The tough Powerpuff tumbled in the air, backwards, due to the blow. She came a halt soon enough and found Rath heading straight for her. Quickly, she went sideway, avoiding the upcoming blow and kicked him at the head, sending him to the ground.

Rath crashed into the ground, which created a crater. He groaned from the impact and almost got up, but Buttercup came stomping down and marched down on his chest. The force from the girl sent a powerful blow through Rath and into the ground, creating a larger crater and a dust cloud.

Through the dust cloud, Buttercup was sent flying out and hit a lamppost. The dust cloud settled, revealing Rath as he panted heavily, "You're going down!"

"No, you are." She swiftly got back to her feet and grabbed the lamppost. When Rath got closer, she put up a game face and swung it at him. However, Rath grabbed it with his bare hands.

"That's your first mistake! When you try to hit Rath, you only make Rath mad!" Along with that outburst, he chops the lamppost into two and sent his hald at Buttercup.

However, Buttercup charged her laser beams and shot it, destroying it into pieces. She still held her half and swung it at Rath's face. The only effect it had on Rath was his head slightly move to the right. Buttercup was surprise, even frozen as she stared at him. That blow should have sent him flying, but instead he hardly moved.

Rath moved his head back at her with a sharp glare, "Well you mess with Rath! You get the fists!"

While Buttercup held the pole, Rath grabbed the other side and began to swing it around himself. Buttercup lost her footing, holding the pole as Rath continued to turn it around him. The increased force became so much that Buttercup couldn't hold on anymore and was sent flying into a building.

For a while everything seems normal, but Rath knew better. Already his enhance hearing could pick up something and he got into a fighting stance. Suddenly, Buttercup burst out of the building, followed by the usual green streak.

"Guess what, dude." She cocked a grin, "You just made me mad." Without saying another world, she clutched her fists and stomp down on the ground, sending rocks flying towards Rath's way.

The massive wave of rocks was too much for Rath to avoid. He was hit by most of them and sent flying into a store, which was deserted. Since the fight started, all the civilians had run off, knowing better to stay away. It was even amazing that the rest of the Powerpuff girls hadn't arrived.

Rath emerged from the store with scratches. The attack did some damage to him, but he channeled all that pain into his anger. He was about ready to charge at Buttercup and attack her when something dropped to the ground. The anger he wanted to unleash quickly left as he looked down at a small purple cube, being the thing that dropped from the sky.

Buttercup also notices this and flew down to ground to look at it, "What is that thing?"

Something of about the cube made Rath very suspicious. He narrowed his sight entirely at it and became wide eyed, "Trouble!"

Suddenly, the cube exploded and formed on the ground, into a purple portal that resembled a wormhole. Constant electricity sparked from it, but didn't hit the heroes. However, since they stood close to it they were stuck in the gravitational pull.

Buttercup tried to fight it back by moving back. With every step she took, it seems the portal kept sucking her in stronger. To make it worse, she lost a step and fell on her back, rendering her vulnerable. If she wasn't in the situation, she would have noticed a flash of green light. The portal continued to suck her that she got stuck in its swirling current. She screamed as the only thing to do, but then felt a rope wrap around her wrist.

Confused, Buttercup looked up and found a humanoid pterodactyl wearing a jetpack being the source. "Hold on!" The strange alien groaned, pulling the other side of the rope.

For a second, it seems that it was working, but the gravitational pull from the portal eventually took over. The green rope snapped, releasing Buttercup into the depths of the portal. Watching while he could, Astrodactyl squawks, "Not good."

Soon enough, like Buttercup, the gravitational pull overpowered Astrodactyl and sucked him in. The portal closed that instant, like nothing ever happened.

So that concludes this chapter. Now I know I've done hero vs. hero thing before but who doesn't want to see the toughest Powerpuff girl fight Ben 10. But can you guess who's responsible for teleporting our heroes away? Along with that, can you guess who the teen scientist is?

I have special plans for this story and will try to wrap it up without delaying like the last story. Unlike the others, this story will be a major crossover to some of Cartoonnetwork shows, so keep your eyes out for them. Also, remember to vote in my poll for my other story, Avengers: Earth's Ultimate Heroes.

Well that's all for now, please review and stay awesome.
