TMNT x Spy Girls (Equestria Girls OCs) Crossover

They all headed straight back to the Turtles' Lair in the sewers.

"Make yourselves comfortable, you two." said Leo.

"Me and Rainbow are gonna be in the dojo to train." said Diamond.

Diamond and Rainbow goes into the dojo to train together.

"Sweet and I will be baking in the kitchen, if you don't mind" said Mikey as they went to the kitchen.

"Heart, Leo and I will be playing Mario Kart, if you don't mind." said Musical as they go to sit down and playing.

Jade decides to watch Diamond and Rainbow train, and Mythic decides to watch Leo, Musical, and Heart play Mario Kart.

"Well, I guess we have no choice but go to either the lab or Mikey's room" said Phred, observing the lair.

"I think that the others might be working for some potions, in the lab still, so Mikey's room have to be it." Zack said, thought of who he think would use the lab at the moment.

Phil and Smiley agreed as they head to Mikey's room to talk about Jade.

"Honestly, I really thought this room was messy, I guess Mikey cleaned it himself" said Smiley, observing the room.

"Here's what we're here to talk about: Jade. I believe her outfit gives me a suspicion that she might be on Shredder's side" said Phil.

"Phil, it can be true, but what if she isn't and that's her everyday wear?" asked Phred.

"It could be a possibly, but what we should think, is her actions and how she talks. I think that she actually would hide her skills, and pretend that she doesn't know anything about Shredder and other." Zack explained.

"Where did you get all that from?" asked Phil.

"Just the purpose of how she speaks." Zack answered.

"I must agree, I wonder that's why she went and watched Diamond and Rainbow train, she must be learning their movements in order to get betrayal on us." said Smiley, as she agreed.

"Plus, I think she has plans already that she'll betray us." said Phred.

"So we found out that her instincts and wordings could be something she's hiding, she already knew how to fight, I believe, as possibly learning a bit more from Diamond and Rainbow's training." Phil concluded.

"And we should keep it to ourselves until it happens, I don't think either the Spy Girls, Hidden Teenagry or the Turtles would believe us, she is hiding them so they think it wouldn't be suspicious" said Zack.

Phil,Smiley and Phred all agreed and when they finished they decided to go out individually to see what's going on.

"I'll keep an eye on her, but won't make it suspicious, You guys can go continue doing stuff." said Phred, they nodded and continued.

In the dojo, Diamond and Rainbow decided to spar each other, but without the weapons, as Jade watches them train. When Diamond blocks Rainbow's attack, she noticed that Jade is watching them, but decides to continue sparring with Rainbow.

A few hours later, Jade hasn't been seen since that she was watching Rainbow and Diamond spar. So, Diamond and Rainbow started looking for her. Rainbow checked the lair, and Diamond goes and searches for her in the city (hoping that she didn't get captured by the Kraang.

"Guys, have you seen Jade anywhere?" asked Rainbow.

"No, I thought she was in the dojo watching you two spar." said Leo.

"Diamond saw her when we were sparring, but that's when was the last time we saw her, and she disappeared." said Rainbow.

"Where's Diamond?" Heart asked.

"She went up to the surface to look for her." said Rainbow.

"Hopefully she'll find her, what if the Kraang tries to capture Jade again?" asked Mythic.

"I think I know what's happening." said Phred as he was just outside the dojo.

"How do you know, Phred?" asked Musical.

"My friends and I have been talking about Jade, how she'd be betrayal, what we didn't talk about, and they are thinking, what if she was leading people into a trap, and faked her innocence? And her outfit and the way we think of her skills. She wants us to think that she don't know how to attack and all of that. We think she's on Shredder's side." Phred explained.

"What?" asked Musical.

Leo and Rainbow are now started to get worried.

"We've got to find Diamond before something bad happens to her." said Rainbow.

"There's no time to lose! We got to go!" said 4-Power.

Everyone got to the surface and started splitting up to find Diamond. Leo, Raph, Musical, and Rainbow started looking in the north of New York, Donnie, Sweet, Mikey, and Heart started looking south, Lightning, and the Hidden Teenagery took east, and the Riddle School took west.

Diamond was at the hidden warehouse where Donnie and Sweet got together, and there was no sign of her, but as soon as she was about to go back to the lair, she sensed that something or someone is attacking her from behind, so she took out her Kamas, and blocks its attack, but it was not an it, it was Jade that tried to attack her.

"J-Jade?" said Diamond shockingly "W-Why did you try to attack me?"

Jade kept a evil grin on her face, and then Tiger Claw shoots a rope out from it's gun, and it hitted Diamond tying her up. Diamond tried to get free, but it was no use, and Tiger Claw and Karai appeared out of the shadows.

"Tiger Claw, Karai?" asked Diamond as she's looks at those two.

"Nice shot, Tiger Claw." said Jade.

"Why are you doing this? I thought you were my friend." said Diamond in a litte furious, but sad kind of way.

"I was never your friend, Diamond." said Jade as she walks up to Diamond. "I'm more than you'll ever be."

Jade started to sing "Open Up Your Eyes" from MLP: The Movie (Parody). As she's started singing it, Jade started to reveal her past.

Jade... I... I had no idea. Diamond thought as she's now starting to feel really bad for her life.

As soon as she's finished her song, Diamond hangs her head feeling bad, and Karai and Tiger Claw grabs Diamond on her arms and picks her up, and Diamond looks at Jade.

"I'm so sorry that you felt so alone." said Diamond.

"I saw the truth, my friends abandoned me when times got tough." said Jade. "I was never your friend in the first place. I was pretending to be your friend so I can study your moves and weaknesses."

Diamond became shocked, but then glares.

"Well.. there's no way that Shredder's gonna know where the Turtles are." said Diamond furiously.

"Oh I'm not gonna tell him.. You are!" Jade revealed as she turns to look at Diamond.

"What?!" asked Diamond in shock.

"Take her to Shredder's lair, and lock her up. I'll deal with her later." said Jade.

"Of course, Jade." said Tiger Claw.

"L-Let me go! You can't do this!" said Diamond in a little panic as she struggles to get out of the ropes.

Tiger Claw and Karai takes her to Shredder's lair into the dungeons.

Maybe I should get the rest... Jade thought as she walked by the hidden warehouse.

The RS,TMNT, SG and HT were finally in a single group, then Ying said "Isn't that Jade by the warehouse?" she observed.

"It is her, she's alone, let's face her!" said Leo as he leaded everyone.

"Well, look who we have here?" said Jade with an evil grin, when they came.

"What did you do to Diamond!?" said Musical, furiously.

"You must know, we... imprisoned her until she'll give up keeping the lair secret" said Jade.

"You won't tell us... WHY you need the location to the lair?" asked Zack, with a mad expression.

"I've also imprisoned her because she has friends that are you, because I was abandoned by my friends in their past cause' of tough times." Jade explained and ignores Zack's question.

"We're going to take you down, there is 19 of us, and one of you!" said Raph.

"Guess again." said Jade with an evil chuckle, as she snaps her fingers calling the Foot Soldiers, Rahzar and Fishface, and Baxter with his M.O.U.S.E.R.S.

"The heck are those..?" asked Smiley curiously.

"Whatever, Smiley, we need to take them down!" said Phred as the rest pull their weapons out.

"Attack!" Jade yelled.

The Turtles, the Spy Girls (except for Diamond), the Hidden Teenagery, and the Riddle School starts attack the Foot Clan. Leo and Phil deals with Jade, Raph, Rainbow, and Musical deals with FishFace, Donnie, Sweet, Mikey, and Heart deals with Rahzar, The rest of them deals with the foot soldiers and the M.O.U.S.E.R.S.

Leo takes down Jade with his katanas, then Phil takes a final touchdown using his Claymore, it failed and Jade pushed him back then move on to go help with FishFace. Once Phred, Smiley, Zack and the Hidden Teenagery were done with the Foot and the M.O.U.S.E.R.S, Phred,Ying,Swag and Electric gone to help deal with Rahzar. Smiley, Zack, Clora, 4-Power and Electric went help against FishFace and Baxter.

Hours later, the bad guys were more tough that they thought.

"Guys, get together!" said Leo. "Mikey, we need to retreat."

The group got together.

"A,B,C-yah!" Mikey yelled as he throws a smoke bomb to the ground and they all disappeared.

"Stay and fight, you cold-blooded cowards!" Fishface yells in furious.

"Let them go, we'll be ready for them, if they ever try to rescue Diamond, they'll be in for a surprise." said Jade with an evil smirk.

In Shredder's Lair in the dungeons, Tiger Claw unties Diamond, and throws her into the cell, and locks her up

"*evil chuckles* And I thought you were the toughest one on your team, Diamond. But, guess I was wrong, cause' right now, you're just nothing but a purple loser, who thinks that Friendship is the key to everything." said Tiger Claw as he leaves with Karai, leaving Diamond alone.

As soon as they're gone, Diamond started banging on her cell door, trying to get out, but it was no use, and got on her knees.

"I can't believe Jade would betray me like this, first that, and now captures me wanting the Turtles' Lair Location. Me and my friends shouldn't have rescued her in the first place." said Diamond.

But then Diamond remembers that Jade told her about her past.

Could Jade be doing this, cause' she has no friends? Diamond thought. But even if they want the location, I'm not gonna tell them, no matter what happens to me, I'll fight to the end. Even if it includes sacrificing myself.

Diamond stands up and started to sing "Fight Song" from Rachel Platten.

As soon as she finished her song, she sat against the wall with her knees to her chest.

I hope they find me soon. Diamond thought.
