Opened my eyes

Author's Note

This is kinda a rough start.

Opened my eyes

"You think you already know me. Well you could be right. Or are you... I remember my heroic duties in the past, ever since Princess Twilight came to Canterlot High, me and my friends were gifted with equestrian magic for magic, and we used it to defeat who will become our friend, Sunset Shimmer. Than after, Sunset Shimmer redeemed by reminding us they we were all friends when saved the school from the sirens known as the Dazzlings. We all transferred our magic to Sunset when she helped the Twilight of our world free herself from the monster she was turned into during the friendship games. And we all pitched together and accepted our superpowers and became superheroes to freed everyone from Camp Everfree. And ever since then... Me and my friends have accepted our fates of being superheroes. We even dealt with lower enemies, like Wallflower Blush and Juniper Montage. And recently we accepted out fates as being superheroes when we took on a creazy monster named Kavitor. My name is Rainbow Dash. And this is my story of how I became... An official superhero for freedom, friendship and justice."

A few days after the events of Spiders and Magic Equestria Girls...

One day at Canterlot High, Rainbow Dash gather all her friends to make an important announcement. "Gather around girls. Gather around." She said.

"What is it Rainbow Dash?" Sunset Shimmer asked. "It better be important."

"Of course it's important. As you all know. We have accepted our roles as Canterlot City's mightiest superheroes." Rainbow said.

"Yeah we know. We fought that giant robot toaster gone bad." Applejack said.

"And we posed heroically." Pinkie Pie said.

"Good times..."

"Lets not forget that monster we fought last week, Kavitor. He was intense." Fluttershy said.

"Well I am planning to become a superhero without ponying up." Rainbow Dash said. "What do you think?"

"Really? How?" Fluttershy asked.

"I still have my super speed, so I'll be speed themed superhero." Rainbow replied. "I've been practicing on my speed a lot when I got home. And it would be awesome to be a for real life superhero, patrolling the city, fighting crime, and bring peace."

"Darling. What's wrong with our pony forms?" Rarity asked. Don't you like your pony ears and wings?"

"Don't get me wrong. I like my pony form. I'll keep it as a last minute transformation. But I'll mostly use it for when we take on a main threat. Besides, there's a while world out there, full of evil, full of people crying out for a hero. And I'm gonna be one of them. I can protect the world." Rainbow Dash said. "Well sorta speak.

"Rainbow, I know I have accepted the fact that we are superheroes. But we don't need to be daily. We're still normal teenage girls. We can be superheroes when threats like Spot, or Kavitor appear." Twilight Sparkle pointed out.

"Twilight, trust me. I know what I'm doing. Our battle with Kavitor opened my eyes. When I look at this room, I don't see normal girls. I see potential. We could all be our own superheroes." Rainbow said.

"Ah was gonna join the firefighter team so I can help them open hydrants to they can get the water easily." Applejack said.

"I was thinking of moving to the Forrest to become an animal guardian." Fluttershy said.

"A firefighter, an animal protector, those are just normal hero stuff. Look, I even have my own costume." Rainbow opened her bag and in it was a Halloween costume she bought from a store.

"See?"

The girls started to laugh. "That's silly Rainbow Dash, since when is pink your color?" Pinkie Pie said.

"That's really is silly." Applejack said while laughing.

Rainbow Dash looked closely at her costume. "Oops." I must've mistakes it for blue." Rainbow Dash quickly changed out of her costume and felt embarrassed.

"Listen Rainbow Dash. It's up to you if you want to be a costumed hero. But we're not interested. We are all going our seperate ways to find our place in this world now that we are superheroes." Sunset said.

"Fine. I can be a superhero. And I know just the perfect outfit. My hair is colorful enough. I'll show you all next week." Rainbow said. "Toodles." She left to figure out what could she wear to start her job as a crime fighter. She has her speed, she has dashing good looks. And she's energetic.

Later, Rainbow Dash was practicing her speed on a treadmill, then She went to a local gym and lifted a few weights for her arms and legs to give them a little boost. She boxed on a sandbag to give her a boost in fighting with her hands. And she is already a black belt in karate so she feels prepared for whatever comes her way.

She went online and bought a white woolly onesie with a white hat and some white gloves and to see what she would look like. She put some white socks on but shoes. She looked at herself in the mirror and realized what she made of herself.

"I look so cool. I may need a mask, not too simple, a red one, they would consider me a vigilante. I'll look so awesome as a superhero. Tomorrow I'll test out my speed with my official supersuit and then I'll start my new life of being a superhero. This is going to be awesome. I don't think I'll need a name for myself. Everyone was use to me with magic, I'll just call myself...Sonic Rainboom, the fasted girl alive." She said.

Rainbow Dash keoted her suit on as she goes to sleep to get ready for the morning. She was finally going to get her wish of being her very own superhero. She dreams of fighting armed robbers, ninjas, and supervillains that want to take over the world. But she'll have to make sure she won't get to exited about fighting a supervillain, and she should not get to overly excited or else she will be taken down easily, and sometimes being a superhero is not always going to be easy. But what ever comes her way, she'll see it though.

To be continued...

Gotta go fast

It's been 3 weeks since everyone went their separate ways. Applejack and Spike stayed behind with Wallflower's help to protect Canterlot City, Fluttershy went to camp Everfree, Sunset had recently left for a city in Canada called Forrestropolis. Rarity and Pinkie Pie traveled the world, and Twilight went to New York City to be with Peter Parker. As for Rainbow Dash, after entrusting Canterlot City's safety to Applejack. She went outside of the city.

"Alright... Focus... Gotta go fast...

Using her speed, she raced away from Canterlot City. "Canterlot City may be relaxing but it will be great to be back in Cloudsdale Town." She said to herself. "Maybe I'll be the best superhero for it." She raced as fast as she can hoping to remember where Cloudsdale Town was. She remembers her parents cheering for her when she was leaving to Canterlot City for boarding school. Her parents has high hopes for her ever since she was born. Although she thinks it's embarassing, after saving the city a few times with her friends. Maybe she can make them if they would cheer her on as a superhero. Protecting the world from the forces of evil.

1 hour later...

After a super long run even though it may take a few seconds. Rainbow Dash stopped at a few fast food stops to eat some nice bacon king burgers, and to use the bathroom after she was finished. She ran for 30 seconds until she saw some familer houses and stores. She found the sign that saids 'Welcome to the town of Cloudsdale.'

"Aw yeah. I did it. I'm home." Rainbow Dash said. "Now if I remember..." Rainbow Dash quickly found her house and knocked on the door. "Hi Mom. Hi dad. I'm home."

"Rainbow Dash!" Rainbow Dash's dad Bow Hothoof and her mom Windy Whistles hugged their daughter in welcoming her back home.

"It's so good to see you again Dashie." Bow said.

"We thought after you left to Canterlot City, you'd never wanted to see us again." Windy said.

"What makes you say that?" Rainbow Dash asked.

"Well after what you said to us a while back after your first year in CHS, we realized you were right. We have been clingy to you." Bow said.

Rainbow Dash remembered what she said to her parents those years ago. "Everywhere I go, you keep on cheering for me every time I lose. Some people even say you were cheering me on when I was being born. Well I'm sick of it. I'm going to live with my friend Fluttershy so I can finally get some forever space. I never want to see you again." But every since that day, she did felt a little guilty. Fluttershy has seen those types of scenarios before. "Look guys. I'm sorry for what I said. But I've changed. I said those things cause... mostly teenagers say mean things to their parents cause..."

"Teenagers thinks they don't need their parents anymore and that they know better and that they think they did their job?" Rainbow Dash's parents finished her sentence.

"Wow, I've been watching too much Disney Channel." Rainbow Dash said to herself as her parents nodded. "Boy, do I feel like a hypocrite."

"But we have seen you on the news a few times. Turns out you've become quite the superhero." Bow said.

"Yeah. You've saved Canterlot City plenty of times from an evil demon, wild vines, an evil toaster robot and a monster bent on destorying the world." Windy said. Rainbow Dash knows her parents are talking about Sunset, Gloriosa, and Kavitor. She can still remember how she and the others disappeared into nothingness when Twilight, Sunset and Gloriosa were defeating Kavitor. "After everything you have been through, we were so proud of you. That's when we realized your not a little girl anymore. And we should respect your space."

"That's why I'm here. I was hoping you can forgive me for lashing at you years ago when I left Sky Hills." Rainbow asked.

"Of course we can forgive you." Bow said. "Your still our daughter and we still love you." They all embrace each other with a hug. "Now I'm gonna go get some take out for dinner, I'll see you in a few minutes." Bow left to his car to go to a fast food place to order some take out.

Rainbow sat down with her mom Windy. "So you know, I do plan to become a superhero." Rainbow said to her mom.

"But you're already a superhero." Windy said as she shows her daughter the poster of her in her magical transformation.

"But that's more like a team up think me and friends did. I'm talking about becoming the superhero I always want to be, no wait, what I was meant to be." Rainbow said as she got out her neckless. "See this mom, this is a geo. It's what gave me my complete superpowers. My friends have them too. Twilight can levitate magic, Rarity can forged diamond energy, Applejack super strong like the earth itself, Pinkie Pie is a party demolition, and Fluttershy can communicate with animals. As for me, I have super speed. So i can go as fast as I wanna go. I'm basically like the Flash."

"Really? I like to see that. Is that why your wearing that Polka-Triangle costume?" Windy asked.

"It's a containment suit I bought online. It felt comfortable and the cool grey one was taken so this was all they had left. Apparently it a birthday containment suit." Rainbow explained. "I'm going to start my superhero career. I will be known as... The Sonic Rainboom, the fastest girl alive. And I can run around the world and fight crime wherever I go."

"That's cool to hear Rainbow Dash. Your dad and I will really be proud of you for making a difference in the world." Windy said.

Later Bow got the food order and they enjoy their dinner. Windy explained to Bow that Rainbow Dash will be the world's newest superhero speedster. Bow was exited. But for now... It's getting late. Rainbow decided to go sleep in her old room. And be prepared for tomorrow for that's when she will begin looking for potential crimes... "This is going to be... Awesome..." She said as she yawns.

To be continued...

A superhero I was meant to be.

The next day...

Rainbow Dash woke up and started to workout a little. Then she rushed downstairs and ate some breakfast. Her parents went to work so she has the whole day to relaxing and finding crime. But she noticed that there was a crime spree going around in Sky Hills. Smoke bombs at banks, people being chased by muggers, and a lion ran out from the zoo.
"All right! It's hero time!" Rainbow Dash said. Her first stop was the bank. She noticed 2 or 4 robbers getting away.

"He he he, with this amount, we can finally get rewarded for the boss lady." The robber said.

Just then, they heard a noise coming from outside of the bank. "Sorry boys, but I can't let you go off that bag of loot. That type of treasure belongs in this pirate ship." Rainbow Dash said while trying to make an entrance. She walked out of the bank to show herself. "Now, I like you all to make a withdrawal or I'll show you how it's done."

The robbers laugh at Rainbow Dash. "Why are you dress like that?" The robber asked.

"Yeah, who are you, Polka-Dot Man's daughter?" The other robber said while laughing.

"You going to throw those colors at us like Polka-Dot Man? Ha ha ha ha ha!" The third robber said.

"Your pissing me off now." Rainbow Dash said as she used her speed punches the robbers, one by one. The others robbers were shocked that she moved fast. They tried to get out their guns but they were not fast enough. And Rainbow Dash finished them off. "The name is Sonic Rainboom. Don't forget that." Everyone cheered for Rainbow Dash. "Thank you very much everyone, but I'm not done yet. I have other heroic duties to fulfill." She ran to the muggers chasing some innocent women that will snatch their purses. But luckily Rainbow Dash ran in so fast she grabbed the 2 muggers by their heads and ran in a speeding circle and threw them to the police station.

"Wow. Your amazing." One of the women said.

"All in a day's work." Rainbow Dash said. She lastly ran to where the loose lion was. "Nice kitty." The zookeepers where trying to get the lion back to the zoo but the lion was vicious and stubborn to listen. Rainbow Dash came just in time used her speed to push back the lion. She ran very fast while pushing the lion back into its cage. The lion was trumastized of the speed. And was a little confused, but the lion knew it was back in its cage. The zookeepers thank Rainbow Dash for everything. And some new reporters came to interview Rainbow Dash.

"Despite your baggy, campy, costume, you are a superhero?" The reporter asked.

"Yes. Yes I am." Rainbow Dash said.

"Do you have a name hero?" The reporter asked.

"Why yes." Rainbow Dash said. "Cloudsdale and the rest of the world... I am the fastest girl alive. Call me... Sonic Rainboom!"

"You heard here first folks. This new superhero will protect Sky Hills and the world, for her name is Sonic Rainboom. We'll be expecting big things from her."

Meanwhile...

In Canterlot City, Wallflower Blush, also known as the Labyrinth was looking at a jumbo screen. And sees that Rainbow Dash finally became the superhero she wanted to be. "Well I'll be. She wanted to be a superhero. And she got her wish." She said. "Good for her."

Meanwhile...
In Forrestropolis, Sunset Shimmer sees Rainbow Dash on a big tv as Rainbow Dash was now confirmed as a superhero. "Well, you got your wish Rainbow. Sunset said.

Meanwhile...
Somewhere in China, Pinkie Pie was watching some TV while she found out Rainbow Dash became a hero. "You did Dashie. You did it."

Meanwhile...

"Those fools should be back hours ago. Why is it taking them so long." A voice said. Just then he saw the news on TV that some robbers have been taken care of and it was thanks to the new superhero, Sonic Rainboom. "So that's what happened. That meddle some speedster ruined it. Well that's not going to stop me. Washout!"

A girl in a black and green suit came into where the voice guy is."Yes Speed Demon?"

"You'll be going back home for a mission I choose for you apprentice. This new hero Sonic Rainboom had meddled in my affairs. I need to know more about her. Go there and face her." Speed Demon said.

"Sure thing... Boss." Washout said as she left.

"I better not have her lose, otherwise I'll have to take my power i transferred to her back." Speed Demon said. "And while Hyperion is freeing Zarda, I'll go and free Nighthawk in the mean time..."
