"Hi there. You must be Isabelle." The girl said. "Your mom told me about you."
Its been a few days since Spider-Tsundere and the newly acclaimed Sonic Rainboom stopped the Pony of Shadows from destroying the world, Since Principal Celestia is suspended from CHS for releasing an ancient monster from Equestria, Rainbow Dash decided to hang out with Isabelle to know why she, her friend Tira and her mother Penelope are in Canterlot City. "So let me get this straight." Rainbow Dash said. "I turn my back and all of a sudden, Celestia, the principal of the school I love, get's suspended?"
"Apparently. For working with some dark magic." Isabelle said. "I have a feeling Cinch does want her to get fired."
"Well too bad. That woman already tried to take over CHS before, but she failed thanks to me and my friends." Rainbow Dash said. "So your a superhero too?"
"Well, Principal Celestia did told you about me so yeah." Isabelle said. "This bracelet I have is magic. I say some command words and Bibbidi-Bobbidi-Boo, I transform into Spider-Tsundere."
"Whoa, that's awesome. But I'm trying not to trust you." Rainbow Dash said.
"Is it because you never see me in Canterlot City before and that a damaged little girl like me with a tragic backstory cannot be trusted?" Isabelle suggested.
"How did you know?" Rainbow Dash asked in shocking confusion. "Are you related Pinkie Pie?"
"No. She seems like if Deadpool and Harley Quinn had a baby." Isabelle said. "I inherited my dad's detective skills."
"Okay that sounds not too crazy." Rainbow Dash said. "So why are you here?"
"Just between the two of us..." Isabelle whispers in Rainbow's ear. "My friend Tira Stars and I are investigating cosmic waves, some of it hit our home in Neo-Tech City, Japan, and we tracked the source of the waves to this city."
"What waves?" Rainbow Dash asked until she remembers. "Are you talking about the reset?"
"The reset?" Isabelle asked. "Do you know about something about it?"
"Yeah. Canterlot City had ripples and my friends Twilight Sparkle and Sunset Shimmer stop the monster who was about to destroy all of reality." Rainbow Dash said.
"Who was this monster?" Isabelle asked.
"His name is Kavitor, he's from an alternative version of Equestria, bent on destroying Twilight Sparkles through out time and space." Rainbow Dash said. "But like I said, Twilight and Sunset defeated him 2 years ago."
"And his destruction created a backlash that restarted the multiverse and altered the earth." Isabelle said. "That can explain why Canterlot City is now on the radar back at my home. Kavitor's death must've merged some cities of my world with yours."
"Your saying your from an another world?" Rainbow Dash asked.
"You could say that. Have you heard of Cyber-Shark?" Isabelle asked Rainbow.
"Yeah he's the cyborg dude from another dimension, my friend Twilight met him while trying to save me and my friends from Juniper Montage." Rainbow Dash explained.
"Yeah, I know about him. So his city Forrestropolis is part of this earth too now." Isabelle said.
"Sunset did told me she was going to Forrestropolis." Rainbow Dash said. "I just thought she would... Nevermind." Rainbow Dash said.
"Rainbow, this is big. If Kavitor merged parts of my earth with yours I gotta go tell Tira. Wanna come?" Isabelle asked.
"Why me?" Rainbow Dash asked back.
"Because you, and 50% of Principal Celestia are by far the only ones that know of my real intention on this city, plus, if you coming back to Canterlot City, maybe we can be friends." Isabelle explained.
"Okay. Let's go." Rainbow Dash said. "Hop on my back, we're get their lickety split." So Isabelle got on Rainbow Dash's back and held on as Rainbow Dash ran through the speed of light. Isabelle showed her where she, her mom and Tira lived. "Never thought you lived in this expensive apartment. You must be living the suite life."
"It's only temporary. Plus Tira is very rich. So she's letting my mom and I live here till we complete our investigation." Isabelle said as they both walked inside the apartment. They went to the elevator and to brought them to the floor where Isabelle lives in.
When they got off the elevator, Isabelle explained some stuff to Rainbow Dash. "So your superhero team is called the Revengers?"
"Pretty much yeah. We've been doing the team thing for only 2 weeks. We're still pretty much getting used to it." Isabelle explained.
"Well, I only heard of the Avengers." Rainbow Dash said. "You know, the team of Earth's mightiest heroes."
"I heard about them in the comic books I read. Never thought they exist in where you are." Isabelle said. "This only proves more that my Earth has merged with your Earth." Isabelle opened the door to her room where she lives. "Mom I'm home, and I brought a guest."
"What a coincidence." Penelope said. "So do I."
Isabelle looked at the girl sitting next to her. She was wearing a purple hat, her hair was purple with a turquoise highlight.
"Hi there. You must be Isabelle." The girl said. "Your mom told me about you."
"Thanks. And... Who are you?" Isabelle asked.
"Starlight Glimmer. Long time no see." Rainbow Dash said as she ran to give her a hug.
"You know her?" Isabelle asked.
"Yeah. She helped me and my friends during Juniper Montage's rampage 2 years ago." Rainbow Dash said. "How you've been?"
"Also, Mom how did you meet her?" Isabelle asked.
"While I was flying around Canterlot City, I saw her coming out from the school's statue. She was in a panic so when I flew down, she looked like she's been through a lot, I told her calm down, but she fainted so I brought her back here to cooperate." Penelope explained.
"My panicking is very important. You see, j have an urgent message from Sunset Shimmer that I need to give to you." Starlight said.
"What is the message." Rainbow Dash said.
Starlight was thinking then she realized. "Dang it I forgot. No wait. It's right here." Starlight pull out Sunset Shimmer's phone but it was low battery. "Oh shoot. I'll play quickly."
Rainbow Dash, Isabelle and her mother Penelope looked at the phone, and they see Sunset Shimmer running away. "Rainbow Dash, it's me. Sunset Shimmer. Listen to me, I have an urgent message you and I couldn't send it in time cause it's too much memory, but it's very important you get this because-" the video stopped cause the battery died.
"Because what?!" Rainbow Dash cried out in disappointed, "WHAT IS IT?!"
"Sorry. Phones don't work probably in Equestria, so I had to rush through Twilight's portal to get back here." Starlight Glimmer said.
"Don't worry. We can charge it." Rainbow Dash said.
"Rainbow's right Glimmer. We'll charge the phone and we can listen to the rest of the message." Isabelle said. "Speaking of urgent, hey mom, where's Tira?"
"I don't know. She hasn't came back yet." Penelope said. "Maybe she's running late."
"Perhaps." Isabelle said.
Just then... Penelope's spider sense went off. "Girls duck!"
The window at the side of the room shattered and the part of the wall. Just then a mysterious figure walked in stole Tira's USB. "Ah... That tip I got from the Cabal is true. Now with this, perhaps there is an energy source that will belong to Tigershark!" 
The creature introduced itself. "Thank you for the gift ladies. I'll come back to feast on you later once I gain power."
"Who was that freak, Cyber-Shark?" Isabelle asked as the other girls were getting up.
"No. He calls himself... Tigershark." Penelope said. "And he stole the USB stick."
"Oh no!" Isabelle said.
"Why did that... Shark man need with that stick?" Starlight asked.
"It carries all the information about the cosmic waves. If he finishes the mystery of the waves, he'll locate it around Canterlot City and try to harness it and become unstoppable!"
Starlight and Rainbow gasped. "We can't let that happened." Penelope said.
"Your right Mom. We can't let that happen. We have to stop that Tigershark!" Isabelle said.
"Count me in!" Rainbow Dash said.
"I'm in too." Starlight said. "I need some action, and luckily Sunset has taught how to use my magic in this world."
"Alright then... Web on!" Isabelle said as she transforms into Spider-Tsundere.
"Whoa that is so cool!" Rainbow Dash said. "Pony up!" She cried out to transform into her pony form.
Starlight Glimmer got into a fighting pose as Penelope put on her old uniform to become Spider-Guardain.
"Come on girls. Let's go stop that evil fish!"
