The next day at school...
"So let me get this straight, the team this school has is called the wondercolts?" Isabelle asked.
"Yeah." Diamond Tiara said.
"That's interesting." Isabelle said.
"Have you heard the news last night. Some thief got scared for life, thanks to some new kind of superhero." Babs Seed said.
"Oh yeah I heard of that." Derpy said. "She seems to be a spider themed superhero."
Isabelle and her classmates were have lunch while talking about what happens on the news.
"You think Spider-Girl came back?" Babs suggested.
"Who's Spider-Girl?" Isabelle asked.
"Spider-Girl is secretly Twilight Sparkle. She became known as Canterlot City's greatest superhero. And because of her, her friends became superhero too." Derpy said.
"Really. Well, she seems to be the one who started it all." Isabelle said.
"You have no idea missy." A voice said.
Isabelle turned her head to see 3 girls coming to sit with her and her classmates. "Oh hi there." Isabelle said. "who are you?"
"I'm Applebloom. Babs Seed's cousin."
"My name is Sweetie Belle."
"And I'm Scootaloo."
"Nice to meet girls. I'm Isabelle." Isabelle introduced herself.
"You look pretty cool Isabelle." Scootaloo said.
"How so?" Isabelle asked.
"Because of that scar." Scootaloo noticed as she points. "I mean, it makes you look very cool."
Then Applebloom slapped Scootaloo. "It's not polite to point at someone Scootaloo." She said.
"It's fine. But this scar came from... Meh, of forget it." Isabelle said.
"She got her scar from falling into acid." Babs said.
"Oh... I'm so sorry." Sweetie Belle said.
"It's fine. I feel fine afterwards." Isabelle said.
"So what were we talking about again?" Diamond Tiara asked. "Oh yeah the spider heroine."
"Yeah. She seems to be cool." Scootaloo said. "But she had a weird name."
"What is it then?" Isabelle asked. "Is it Spider-cinder?"
"No, it's like... What in anime would say." Scootaloo said.
"Oh I got it. Her name is Spider-Tsundere." Applebloom said. "And the best part of her is... She seems to be our age."
"Well I got something you'll see." Isabelle said as she got her phone up. "Look."
The girls look at the phone. "Yea that's her." Scootaloo said. "So that's her?" Isabelle nodded.
"Where did you get this?" Diamond Tiara asked Isabelle.
"Neo-Tech City." Isabelle said. "That's where I live."
"Neo-Tech City?" All the girls asked in confusion. "What kind of city is that?" Sweetie Belle asked.
"It's where I live. It was once Tokyo until it was destoryed by alien invaders. And workers and scientists from New York City came to help the surviving citizens of Tokyo rebuild the city into a stronger city." Isabelle explained. "Thus Tokyo became Neo-Tech."
"Whoa. That's sound heavy." Scootaloo said.
"I was baby when Neo-Tech City was fully rebuilt." Isabelle said.
"I like to see that city someday." Scootaloo said.
Afterwards the girls talked about how Spider-Tsundere is awesome especially since she looks like her their age and height. Isabelle became good friends with the Crusaders.
Later...
Isabelle was walking in the hallway, while talking in phone to her boyfriend Chad. "Yeah, it's good to know Neo-Tech is safe thanks to you and the others. Tell my dad I'll talk to him later. Love you babe. Bye." Isabelle hanged up her phone and she noticed principal Celestia walking like no one should see her. Isabelle decided to see why. She followed Celestia into the science room. "Strange. Why would she come here mysteriously. It's not like she has something to hide." Isabelle said to herself. She transformed into Spider-Tsundere to use her hyper-sense and phase through the door and under a desk and transformed back and peeks her head up and sees Principal Celestia with some strange looking artifacts. And one specific artifact that is covering her body with some black looking substance. Isabelle recognized that type of substance. Its the same substance she saw in her nightmare. She screamed as she saw it. "Get away from that thing!"
Isabelle ran to get it off but it got off Principal Celestia as she saw Isabelle come towards her. "Isabelle, what are you doing here?"
"An even bigger question, how did you get that stuff off you?" Isabelle asked. "What is that thing, and what are those? They seem to be artifacts?"
"Your correct about a few things." Principal Celestia said. "These are what was left the Equestrian artifacts that came to Earth."
"Equestrian artifacts?" Isabelle was confused. "Then she remembered something. You mean these artifacts are from another dimension called Equestria?"
"Yeah. How'd you guess?" Principal Celestia asked.
"Long story short. I inherited my dad's detective skills and instincts." Isabelle said. "But I've also read about these and when they got destroyed sometime ago?"
"They were, but I'm been collecting some pieces of what was left of these artifacts. A piece of the gems the Dazzlings used during the battle of the bands. What's left of Twilight's magic capture device during the friendship games, a fragment of the memory stone that Wallflower Blush used to get rid of Sunset Shimmer's memories and her friends memories. And this time twirler. That can do over an entire day, Sunset Shimmer and Pinkie Pie managed to destroy it from some pop singers." Principal Celestia explained.
"So you been collecting some pieces of the items that influence magic?" Isabelle asked. "Then what's with the black substance?"
"Funny you should asked." Principal Celestia said. "I've discovered this shadow piece, it seem to be also from Equestria as well. From my understanding, this holds some kind of shadow magic. But maybe if the some help from these items I can make some immunity from the magic."
"Immunity?" Isabelle asked. "That seems fair. But this school has experienced Equestrian magic in corrupted hands. I've read the yearbooks the records. And even see that use it for good. But we don't know much about Equestrian magic."
"I know. I've been testing out something interesting with the shadow substance. I somehow managed to replicate it." Principal Celestia said. "I call what you saw in me, a synthetic shadow."
"Why would you make this?" Isabelle asked.
"I have my reasons. But let's just say, If you had something important to you that you wouldn't give up on it no matter what"?" Principal Celestia asked. Isabelle looked down a little. "I plan for the students to use these, to protect themselves from the magic that's now around Canterlot City. But I still need help testing it out." Suddenly Principal Celestia had an idea. "Hey, since you are the only one that knows about this, why don't you be my assistant?"
"Assistant? Me?" Isabelle thought. "I'll think about it. But I'll keep this a secret for now. I'll let you know." Isabelle left the science room and she walked passed the gym and she noticed something. She saw a guy working on what looks like a robot. "Whoa. That is a delicious robot." She said as she walked up to the boy.
"Delicious?" The boy said.
"As in very cool I mean." Isabelle said.
"Oh, thanks." The boy said. "I don't think I've seen you around this school before."
"My name is Isabelle. I'm new here."
"Nice to meet you Isabelle. My name is Microchips." They shakes hands.
"Now why did you say delicious?" Microchips asked.
"Because you basically made a toaster robot. And I love me some toast. Smothered with cream cheese, bacon and sausages." Isabelle said.
"Well to be fair, my robot, the JVJ-24601, its not a robot for eating toast out of." Microchips said. "Its basically my pet that I made. But after it lost in a pet race, i decided to give it a little upgrade."
Isabelle noticed the claws and the tank wheels. "Well it looks pretty cool." She said.
"Well I'm going to activate it. It had some bugs. But i hope it works perfectly." Microchips said. "Well here goes."
Isabelle looks at the robot more carefully. "I bet Mysterious would never have this much problem in he looked like that." She thought to herself.
Microchips activated the robot, it came up. But... it sees his creator and how he shut him down from when it lost the pet race months ago. 
It grew angry.
"Uh... Micro? Did it had... emotion?" Isabelle asked.
"Yeah..." Microchips said. "Why you ask?"
"Did you add weapons onto your robot." Isabelle asked.
"Yeah, I want to be like a defense thing." Microchips said.
"Then why is it looking like it wants to destroy you?" Isabelle asked.
Microchips look at his robot and it gave him the evil glare. "Oh shoot."
"isabelle... run!" He said.
Isabelle and Microchips ran away from the robot as it shoots lasers at them. Isabelle grabbed a machine ball and threw it at the robot. Then she grabbed a bat and starts hitting it. But the robot threw Isabelle out of the gym. "Isabelle! Are you alright?" Microchips asked as he ran to Isabelle.
Isabelle got back up as she laugh maniacally. Microchips sees her eyes glowing purple, he was a little scared. "Sorry. You didn't have to say that. Its kinda my condition."
"What is going on here?" Both Isabelle and Microchips heard a familiar voice as a woman walked up to them.
"Vice Principal Luna." Microchips noticed. "My robot's gone haywire."
"More like revengey." Isabelle said.
"Your robot?" Vice Principal Luna said. "And that's why the lockers are like that."
"It threw me there." Isabelle said. "But it looks like it wants to destroy everything."
"If my robot leaves the school. It'll cause damage on the city." Microchips said.
"Then it needs to be stopped on school property." Vice Principal Luna said.
"I'll got set some help." Isabelle said as she ran away to go transform.
Later...
The robot was about wreak havoc in the hallways, all the students ran screaming, but then it heard a voice. "Hey yummy!" The robot turned it toaster heads as it sees Spider-Tsundere. "I'm gonna eat you up." She said. "After I get rid of your circuits."
The robot charged at Spider-Tsundere and shot his lasers at her. She dodges the lasers and shot a web line at the toast head, and ate it. "Toasty!" The robot popped out another toast head and looked at Spider-Tsundere with anger.
"And now I made you pissed."
Spider-Tsundere latched on to the robot's body to try to pin it down. She started to use her stinger blade.
The robot screamed as it grabbed Spider-Tsundere with its claw and shoots its lasers at her. "Spider-Tsundere!" A familiar voice said.
The robot and Spider-Tsundere looked at Principal Celestia as she was shocked to see Spider-Tsundere blasted by the robot. "How did you know my name, forget it. Get out of here" Spider-Tsundere said as the robot contined shoot its lasers at her. She start laughing insanely as her as her eyes glow purple again.
"Are you... laughing?" Principal Celestia asked.
The robot looks more angry and the lasers are not hurting her. "Is that all you got. As long as I'm insane, you can't hurt me." The robot was furious it the lasers was too strong it burned off its own claw and Spider-Tsundere was free. "Ha ha ha ha, Now its my turn." Spider-Tsundere jumped on the robot and tried to electrified it with its electric venom, but it only made it stronger. "Oh crap baskets." She said. The robot shot electricity at Spider-Tsundere and she dodged it. as it goes back to the gym and break the wall and get free.
"You alright?" Principal Celestia asked.
"I'm okay." Spider-Tsundere said. "But how do you know my name? Ugh, nevermind. I need to stop that robot. But it seems strong to take down. My magic electricity doesn't seem to stop it that much."
"But we do know something that can stop it." Principal Celestia said. "The synthetic shadow."
"Synthetic shadow?" Spider-Tsundere asked. "What are you talking about?"
"You know, the substance you saw me in earlier, I told you about it already." Principal Celestia said.
"Okay, I wasn't here earlier." Spider-Tsundere said.
Principal Celestia sighed. "Look, I know keeping your identity a secret is important to you, but we don't have time to pretend you don't know me. This is our only chance to stop that robot before it destroy this school and the city. But in order to do that... your gonna have to trust me Isabelle."
"Wait WHAT?!" Spider-Tsundere said in shock.
