TMNT x Spy Girls (Equestria Girls OCs) Crossover

Karai asks her how her family died.

"So tell me, how did your family died?" asked Karai.

"Well... it's a long story... It all started 2 years ago. Before I made friends and become Spy Girls. My family were going on vacation to Everfree Forest, back in my dimension. They left me in charge until they got back, but... a week later, I got a call from Gloriosa, a leader of the camp called Camp Everfree, telling me that they died in a real bad car accident. So I went to the hospital to see them before they actually did die. My mother whispered to me her final words 'Y... You given us an amazing life, we all love you, Diamond.' I was really depressed for 4 weeks, because then try to forget about it... but I kept on getting nightmares about it every night, because of that." Diamond explained. "But when I had friends who always have my back... It's like their more than that, their like... their like my family."

"Diamond... I had no idea that you felt like this." said Karai.

"Yeah, I know." said Diamond.

Diamond then see the Shellraiser.

"Karai, you need to go, before they see you." said Diamond.

"Meet me later at the Byerly Building?" asked Karai.

"Hopefully without them knowing." said Diamond.

"See ya then." said Karai.

Karai turns into a snake and gets out of there before she's been seen with Diamond. The girls goes up to her and gave her a hug.

"Oh thank God that you're alright, Diamond." said Rainbow.

"Wait, how did you get out of Shredder's lair?" asked Clora as her and her gang goes up to them with the Turtles, and the Riddle Kids.

"It's a long story, but it doesn't matter anymore." said Diamond.

"Yeah we're just glad that you're safe, Diamond." said Ying.

"Thanks, Ying." said Diamond. "But we should head back before Shredder's goons try to find me or any of you."

"My thoughts exactly." said Donnie.

They all got on the shellraiser and headed back to the Turtles' lair.

As soon as they got there, they all sat down trying to relax, except for Diamond. Diamond went to the dojo without them knowing, and she sees Splinter in there, meditating. Diamond goes up to him quietly without disturbing him and sat right next to him. Splinter opens his eyes and looks at Diamond, as she looks at him.

"Is it ok if I meditate with you, Splinter?" asked Diamond.

"Of course." said Splinter.

Splinter and Diamond goes into meditation. After 5 minutes on the meditation, with both of them glowing, Diamond's glow was started to fade as in she couldn't concentrate after the conversation she did with Karai.

"*Groans a little quietly*" Diamond groans.

Diamond tries to concentrate on the meditation again, she started to glow lightly a little, then started fading again.

"*Groans*" Diamond groans.

Splinter looks at Diamond.

"Something wrong, Diamond?" asked Splinter.

"*sighs* I couldn't seem to concentrate for some reason." said Diamond.

"And why is that, Diamond?" asked Splinter.

"...If I tell you this, would you promise not to tell anyone else?... it has something to do with Karai." said Diamond.

Splinter was kind of shocked on what she said, but if it really bothers her, he would have to trust her.

"Whatever it is, I won't tell my sons about this, or any of your friends." said Splinter.

"*sighs* Ok, so... after Karai took me out of Shredder's lair, and went to Coney Island. We had a little conversation about... well... Karai told me that her mother died... and she told me that, you took her mother away from her. I know it's not true, right?" asked Diamond.

Splinter stands up.

"No... it is not true... but the truth is... almost as difficult." said Splinter as he makes his way to his room.

"Please Splinter, tell me... trust me." said Diamond.

Splinter turns around facing her.

"Karai... is my daughter." said Splinter.

"What?" Diamond whispers in shocked.

Splinter nods.

"Come with me." said Splinter. "It's about time I tell you... my past. Before I had my sons."

Diamond goes with Splinter to his room.

What they didn't know is that Lightning and Rainbow were listening to the conversation the whole time.

"Karai was the one who got her out?" whisperly asked Lightning.

"But she's our enemy." whispers Rainbow.

"But he also said Karai... was his daughter. That can't be true, right?" whispers Lightning.

"We'll get more answers later, we need to relax." whispers Rainbow.

"*sighs* Yeah, your right. Come on." whispers Lightning.

Lightning and Rainbow goes back to the living room.

Back in Splinter's room.

Diamond and Splinter sat down across from each other.

"It all started 15 years ago, in Japan, when I was a human back then, I fell in love with a women. Her name was Tang-Shen, and I was not the only one who loved her. There was another man competing for her attention. Oroku Saki or otherwise known as Shredder." Splinter explained.

"Shredder?" asked Diamond.

"Mm-hm. One day he insulted in front of me. He called me many names. I felt I could not let those insults go unanswered. And I lost my beloved Tang-Shen. Before I lost her, me and Tang-Shen had a daughter named Miwa, before she was... you know... and Shredder took Miwa away from me and now she's formally known as Karai." Splinter explained.

Diamond was so shocked on what she is hearing.

"K... Karai is actually your daughter?" asked Diamond.

"Yes." said Splinter.

"S-Splinter... I had no idea they both mean so much to you." said Diamond.

Splinter just nods.

"*Sighs* Believe me or not... you're not the only one who's dealing that kind of situation. Except it's not just my mother... it's actually my entire family." said Diamond.

Splinter became a little shocked.

"Your family? Hm... how did it happen, Diamond?" said Splinter.

"Well... it's a long story... It all started 2 years ago. Before I made friends and become Spy Girls. My family were going on vacation to Everfree Forest, back in my dimension. They left me in charge until they got back, but... a week later, I got a call from Gloriosa, a leader of the camp called Camp Everfree, telling me that they died in a real bad car accident. So I went to the hospital to see them before they actually did die. My mother whispered to me her final words 'Y... You given us an amazing life, we all love you, Diamond.' I was really depressed for 4 weeks, because then try to forget about it... but I kept on getting nightmares about it every night, because of that." Diamond explained. "But when I had friends who always have my back... It's like their more than that, their like... their like my family."

"... You're right about one thing... I'm not the only who's dealing with this." said Splinter.

Diamond nods.

"*sighs* At least I got it out of my system... But... I do have a feeling that Karai still has a good side in her." said Diamond.

"Well, Diamond, allow me to give you this advice. You must trust your instincts, but beware the trap of believing something to be true simply because you wish it to be." Splinter explained.

"So I should trust my instincts, unless my instincts are wrong?" asked Diamond.

"Correct." said Splinter.

"Thanks, Splinter." said Diamond.

Splinter just nods.

Diamond goes out of his room and into the dojo.

Could it be possible for her to be on our side? Diamond thought. Diamond just trains while thinking about it.
