What If The TMNT Had Sisters?

Annihilation: Earth!

The turtles and their sisters along with Casey and April drove though the city in the shell raiser. 
“Whoa, that Triceraton sounds so cool. I wish I could have fought a real, live dino-dude.” Casey said.
“Yeah, right. That dino-dude would have stomped you into a Casey puddle in about five seconds flat.” Raph smirked at him.
“Whatever, Raph. Casey Jones eats dinosaur meat for breakfast.”
“Ugh.” Urte rolled her eyes at Casey’s comment. She laned over to Sim and whispered. “What do you see in that guy!”
“Shh!” Simona covered Urte’s mout sushing her loudy causing everyone to turn to look at them, expect Leo who was driving. 
“What are you two gossiping about?” Raph gave them a poker face. 
“We aren’t gossiping.” Simona removed her hands from Urte’s face. 
“Probably discussing how Zog just let himself fall off the statue…” Mari sighed softly.
“Yes! Thank you, Mari.” Simona pointed at her sister and smiled awkwardly. 
“I'm just amazed there are more aliens out there in the universe other than the Kraang.” April pointed out. 
“I’m not. There’s probably tons more different types of aliens.” Urte pointed out.

“I hate to break up the conversation guys, but someone's been following us for the last five blocks or so.” Donnie turned their attention to him. 
“Weird. I don't sense anyone at all.” April noted.
“See for yourself.” Donnie pointed to the monitor as April walked beside him. 
“It's a Kraang.” Mikey stated as he noticed the man driving in the car.
“Stay on him Leo.” Donnie shouted to Leo who followed the strange car into a corner.

“He's gone.” Leo stated as they all got out of the shell raiser to find no one in the corner. They began to look around. 
“Check it out.” Simona called out as she noticed writing on the wall. ““Turtles, 3117 Bayfront street. Midnight.”” She read out loud as everyone gathered behind her.
“What's that supposed to be his logo?” Raph noted at the chess piece at the bottom of the message.
“It's a chess piece. A bishop.” Leo said.

“For the record, I still think this is a terrible idea, Leo. It's got to be a trap.” Raph said as everyone gathered around the palace.
“Something's up. And I'm gonna find out what.” Leo looked at his brother.
“Dudes, this is the same meat warehouse where we fought Tiger Claw. Come on, I know a back entrance.” Mikey stated before he led the way. 

They all snuck in, sitting on the boards the meat hung from. They noticed the strange man walk in. 
“Shh.” Leo looked at everyone before he noticed Casey jumping down towards the guy. “Casey, stop!”
“Goongala!” Casey attacked the man. But he quickly grabbed his hockey stick and knocked him down. The rest of the turtles jumped down.
“Do not do this.” He said and moved out of the way, dodging all the turtle's hits. Simona and April ran to Casey. Suddenly Bishop kicked Mikey off of himself.
“Mikey!” Leo shouted as he ran to help his brother.
“I am not here to fight you.” The man looked at Leo.
“Too late for that.”  Leo said and charged at him.

The man avoided all possible hits, before taking Leo’s katanas and kicking him down.
“That's impossible.” Leo looked up at the man as his siblings and friends ran in beside him. 
“Turtles, refrain from attacking.” He said and walked over to Leo giving him back his swords. “Believe me when I say, I am not your enemy.”
“And Iveta was just about to suggest to actually stop and listen.” Urte sighed deeply at all the boys.
“You can call me by my Earth name Bishop.” The man introduced himself.
“But you look just like a Kraang.” Casey pointed out.
“I was the one who created this body. The other Kraang copied me. I am a member of the Utrom tribe a small group of Kraang defectors. We broke away from the Kraang Hive Mind many centuries ago.” Bishop unbuttoned his shirt to show his kraang body. 
“Fascinating. It makes sense the Kraang share a hive mind a really stupid hive mind.” Donnie stated
“I have broken my Utrom vow not to intervene in earthly matters, but I must warn you, the Triceratons are coming.” Bishop adjusted his glasses.
“He’s kinda hot…” Mari whispered to Urte who turned red and face plamed.
“The Triceratons? As in plural?” Iveta freaked out.
“But we stopped the beacon.” Leo walked beside her putting his hand on her back.
“No. They are coming, and they are carrying enough firepower to destroy the entire solar system.” Bishop explained causing Mikey to gulp.
“Can you repeat that last part?”
“The news gets worse. The Kraang have finally fixed the Technodrome and are about to invade once more.”
“You have any more terrible news, Bishop, or is that it?” Raph groaned.
“If the Triceratons arrive when the Technodrome rises, they will hone in on this planet and vaporize it.” 
“Sorry I asked.” Raph replied in an awkward tone. 
“Bishop, why do the Triceratons hate the Kraang?” April walked closer.
“That’s a really good question.” Simona added.
“For millennia, the two species have fought over Dimension X. The Kraang use their intelligence to battle their foe, while the Triceratons relied on brute strength and cunning. It seemed the Triceratons would win, but the Kraang used the most powerful weapon in the universe a black-hole generator that wiped out the Triceraton's entire planet. Only a single Triceraton fleet survived. They vowed vengeance. The battle may have ended, but the war has not. It still rages across Dimension X. Now, shall we begin?” Bishop looked at them all.
