I have many stories surrounding my TMNT AU of Shredder and Krangs mutant family, this here is another one which plays shortly after the end of Season 10 of the old cartoon, shortly after the creation of Karaii and co.

Lord Dregg, the ever spiteful, hate filled madman was not happy about his defeat at all and decided to come back even worse as before. Unfortunately for Shredder and Krang, Dregg planned to take revenge on them first before going after these misfits of Turtles.

Alone and without any help this time Dregg works on a plan to once and for all show everyone and really everyone in the known universe and galaxies that he is the most evil and dangerous being ever! And all the other junk he was blabbering about.

Just like Krang and Family he is still trapped in Dimension X, on a far away planet covered up in ice all over. One day however there was word coming up to him about the whearabouts of his self-proclaimed enemies, Shredder and Krang. His fire of revenge flared up again and he began to contact some of his old friends who are known as being A+ spies in all of Dimension X.

They also found out about the newly added support in form of Karaii and the others. And one of them seemed to be predestined for playing out to Dreggs plan of revenge. A mental very labile being with tendencies of self-harm and loner mentality. The perfect vessel for every manipulative asshole around the world to play out their schemes...

Chapter 1:

"Bittersweet Things"

Dimension X, somewhere on a really fucked up planet covered in ice...:

Lord Dregg was sitting on a huge ice-covered rock, brooding over his recent loss against these blasted Turtles and the betrayal of the stupidly megalomanical brain Krang and his wanton boyfriend/alliance partner/whatever you want to name them Shredder. His thoughts were filled with such hate that he not even recognized as his nose began to run for its dear life. Sniffing up the unwelcomed output, Dregg threw his arms in the air cursing loudly.

"They will pay, they all will pay and grovel at the feet of Lord Dregg!" a coughing fit disturbed his perfectly well balanced monologue unfortunately.

"Oh if i just could escape this damned place somehow...only if...oh only i had my beloved ship, heck, even this slime-bucket Mung would be alright to dwell with."

Just as he started another loud rant of cursings he remembered a few friends he could contact. They were also here in Dimension X. He mentally slapped his face.

He had to do a few calls, and that very quickly. Dregg pulled out a strangely looking device and began to bring out an antennae.

...

Meanwhile in another place of Dimension X:

Krang was just finished with their dinner, yes today was kitchen duty for the alien brain which didn't bothered him that much seeing as he could bring in his unbelievable intelligence to yet another aspect of their life in the Technodrome. And for a talking brain his cooking skills were not that bad...
Shredder was training with Napoleon and Karaii to teach them a few tricks he had not show them yet. Both worked great as Team and brought Shredder not just one time on the edge of loosing. He was proud over his two creations and hoped they would show the same strenght when they battled these blasted Turtles again one day.

A sign of him and both children stopped their attack. He took a deep breath and smiled.

"I am proud of you two. You truly developed your skills beyond my wildest imaginations!" Shredder said, patting both Napoleons as well Karaiis shoulders.

"Heck yeah, you can be proud of us dad, seeing as we are nearly better as you!" Napoleon added, smirking his trademark "winner-face", high fiving Karaii.

"Now now, don't get cocky just because you got slightly better as last time. I am still superior to the two of you!"

Napoleon nodded towards Karaii who silently agrees to just shut their mouths against their fathers hurted pride.

"Sure thing dad, just as you said..."

"Father is truly superior over us, isn't he brother?" Karaii said, her face showed not a single hint of amusement.

"Of course he is, how could anyone dare to oppose to this?" Napoleon added with a hint of mockery and began to stretch himself.

"I am hungry dad!" Napoleon whined out of sudden. Shredder sighed and nudged his sons neck with his fist.

"For someone as small as you are brother, you sure have a lot of appetite." Karaii said with a smile, patting her brothers shoulder.

She hitted a nerve here ,seeing as Napoleon hated nothing more as to get reduced to his rather small frame.
Sticking out his tongue to Karaii, the young man huffed annoyed and turned around to dry his sweaty body. He stripped off his shirt and gave a good look on his muscles which made Karaii blush lightly.
Shredder rolled with his eyes and escaped the training room with a sigh. Ever since Krang and himself decided to create these fellas, life was really funny and interesting in the halls of the Technodrome. He recalled his memories of first seeing them as they came out of their testing tubes, freshly designed yet so powerful already. Shredder was more then proud as he saw their creatures coming to life. They all shared his DNA making them to his children in a way. That Krang also had his ioda of DNA mixed in them was bugging Shredder a little bit but he was slowly accepting this fact.

Just as he was loosing himself in the past, he crushed into another one of his creations, one of the more complicated ones. Zheta threw a short look on him, huffed and walked away to an unknown destination but probably down to her laboratory where she resided most of the time.
With Zheta they had made a being so intelligent, yet so dangerously emotionally labile that sometimes even Shredder feels uncomfortable around her. Krang was perfectly fine with her, in fact those two often seemed to represent one side of the same medaille. Sometimes however even Krang does not understand her and wonders about her constant brooding.
They then decided that it probably was just a phase and she would come over it eventually.

The only one who truly was coming through Zheta's thick wall of shielded emotions was Zakary, a young Neutrino who was living on the same asteroid as her family. He was a runaway and decided to life on his own, at the moment in a stuffed out cave near the Technodrome. Zak and Zheta were friends by now, both enjoying the company of each other. He sometimes also sneaked up into her laboratory to spend some time with her. Zak however had to be very careful all the time if he was visiting her. Krang was known for his hate against Neutrinos and Zheta's friend was no expection of this...

Today was another one of these days where the young man visited her. He carefully slipped through the waiting foot soldiers stationed all around the drome, slipping in a corner undetected yet. Zak found a short-cut to Zheta's laboratory and also had the code for these rooms. He quickly dialed in the numbers and sneaked inside her lab.

She was sitting on a table which was covered in various blue-prints of all kinds of things. Zheta not even recognized as Zak tip-toed towards her with a huge grin on his face.
Another leap and he was standing right behind her, putting his hands over her face. At first she flinched but then knewing who it was began to smile.

"Hello Zak, is it yet time for another visit of yours?" she said with a small croak in her voice, she turned around to face her friend. Zheta slapped his hands away playfully and offered Zak a seat at her side.

"Of course it is, i don't see you that much you know? I missed talking with you!" the Neutrino said and ruffled Zheta's hair which made her slightly irritated.

"Stop that please, you know i hate this kind of behaviour...my hair needs to sit straight or else i can't think right!" Zheta said, putting away Zaks hand with a playfully hurted look.

"What are you working on anyway? This looks rather impressive, just like a giant robo-exo-suit. Is it what i think it is?" Zak asked taking a close look on the blueprints in front of Zheta.

"This is a little present for Ukuro...i want to surprise him with this! It's a special exo-suit fitted for his kind of condition..."

Zak saw Zheta's changed look and nodded in understanding.

"You really do care about him do you?"

"Of course i do, he is my twin-brother after all...we have a very special connection, not only physically...we solemnly communicate via telepathy which makes me able to feel his pain and vice versa. We are one being just seperated with different bodies..."

"Sorry, i didn't wanted to sound mean or something." Zak said with an apologetic expression on his face. Zheta nodded and her smile returned.

"It's alright, i know you don't have ill intentions towards him or myself. You are a friend, my friend which i don't say lightly." she added, taking his hands with her own.

"So...do you want to do something special today? I am nearly finished with my project here so i am free for the rest of the day."

"Ohhh, we are adventurous today huh? No prob, how about we amuse ourself with a little trip ton Neutrino? I got a few friends back there who are always up to some fun. I just need to call them and they would get us from here." Zak said, tightening his grip around Zheta's hands. She blushed but was quick to deny this offer.

"Are you crazy? What if one of my fathers see's us? Or even worse, assuming we share some sort of friendship with each other!" Zheta turned around, breaking up the connection she had with Zakary just seconds ago.

"We can be sneaky, nobody would see us." Zak retorted, trying to convince his friend to join in his idea. Just as he wanted to get closer to Zheta, a knock on the door of the laboratory made Zheta jump a few feet in the air.

"Quickly, cover yourself!" she hissed, pointing towards a huge machine. "Hide behind this gadget here, i will tell you when you can come out."

As fast as he could, Zak hides himself behind the machine waiting for whoever would come in.

"Who is it? Can't you see i am busy right now?" she yelled, walking up to the door opening it with a frowned expression. Krang was standing outside with a rather campy looking apron and a smile on his brainy face.

"Dinner is ready, come up and eat with us!" he said, pointing towards the elevator. Zheta nodded meekly and agreed to follow him.

"Alright, i will come as soon i finished this last drawing. It just will need a few more minutes." she added and turned around to walk back to her table. Krang nodded and closed the door behind him making his way up to the dining room.

"Come again later, after dinner i will try to find a way to spend some time with you." Zheta whispered, lookin in Zaks direction. She had a sad look on her face.

"I am sorry." she added with a husky voice and turned around to walk out of her laboratory.

"*sigh* Great...just great." Zak grumbled and began to sneak out of hiding, taking a seat on Zheta's table taking a closer look to the blueprints.

"One thing i have to say...she truly rocks this drawing things"
