Theater Dimension:

A brunette was looking at the book in her hands as a redhead stood next to her as she looked at her creator.

"So, time to bring them in, fearless?" Sophia asked with a grin as the brunette chuckled and smiled.

"Yup. Though I won't be present. Make sure they don't try to kill each other." She said before she disappeared in a flash of light.

Sophia shook her head before looking around and checking her pocket watch.

"Time to bring them in." She whispered before snapping her fingers.

ROTTMNT:

Just as Mikey closed the portal on the Krang, he and his brothers, Casey Jones Jr, April O'Neil, Hamato "Splinter" Yoshi disappeared in a flash of white light.

TMNT 2012:

Just when Raphael, Donatello and Michelangelo brought an injured Leonardo back in the lair, they and April O'Neil and Casey were blinded by a bright light and disappeared.

Theater Dimension:

Sophia winced when a bunch of pained sounds were heard as the guests arrived.

"Whoops! Sorry about that!" She exclaimed as the turtles of the two dimensions all looked confused.

"Um, where are we and who are you?" Rise!Raph asked in confusion but he was standing in front of his younger brothers.

"Um, hang on. There's one more guest that I need to bring in." Sophia laughed sheepishly before snapping her fingers and another flash appeared and what appeared to be an older version of Leo appeared as he blinked in confusion.

"S-Sensei?" Leo looked to where the voice came from.

"Casey?" He uttered in shock and surprise.

The teen nodded and hugged him tearfully. Leo sighed softly and just hugged him back.

"Okay, now that we're all here, let's get with the introductions out of the way." Sophia said as she snapped her fingers again and the injuries on both sides all healed up with 2012Leonardo waking up.

"Um, I guess we'll go first." Leonardo cleared his throat.

"My name's Hamato Leonardo and these are my brothers; Hamatos Raphael, Donatello and Michelangelo as well as our friends, April O'Neil and Casey Jones." Leonardo started as he eyed the big turtle with the red mask.

"Nice to meet ya. I'm Raphael Red Hamato." He greeted kindly with his snaggletooth peeking out in a friendly smile.

"The name's Othello Von Ryan-" The second one started but was cut off by the blue masked slider.

"His name is Donatello Purple Hamato. Don't mind him. Names Neon Leonardo Blue Hamato. The handsome one." Leon said with a smile.

"Sigh. Nice way to ruin the mood, Nardo." Donald rolled his eyes but was staying close to Leon.

"Hi, I'm Michelangelo Orange Hamato!" The last one said with a bright smile.

"Oh my gosh! Dudes, he's so cute!" Michelangelo gushed.

"I'm April O'Neil, nice to meet you." The black teen said and this caused the turtles of the other dimension to stare at her.

"You're April?!" Donatello exclaimed in surprise while looking at his April and the second one.

"Got a problem with that, Dee?" She said with a dangerous glint in her eyes.

"Um, nope! Nothing wrong!" He laughed nervously.

"Well, I'm Lou Jitsu also known as Hamato Yoshi but I'm going by Splinter now." The small rat introduced himself. Hearing that made the TMNT 2012 team to stiffen but made sure it wasn't noticeable.

"I never knew Splinter could be short." Michelangelo whispered to Donatello who nodded in shock.

"Um, well, I'm Casey Jones and I'm from the future." Casey said as he stayed by his sensei's side.

"Well, guess I'm the last one. My name is Leonardo. Leader of the resistance, also from the future." He said as Leon looked at his future self in shock. He looked so cool and is that a prosthetic arm?!"

"Okay, now that introductions are out of the way, feel free to sit where you want but stay with your group. I'm letting you guys move seats if you wanna sit with the other group. All types of snacks will be available on the table on the side and bathrooms are on the left side of the room. Any questions before we start the movie?" Sophia said as April raised his hand.

"Yes, April?" She asked.

"Um, not to be rude but how are we gonna tell the difference between all of us?" She gestured to the turtles and herself with her counterpart and the two Casey's.

"Oh, that's easy. The ones from the TMNT 2012 universe will either go by their full or last names and the ones from the ROTTMNT universe will go by nicknames." Sophia said.

"Then does that mean I can go by Leon?" The slider asked curiously.

"Yup."

"Great! That means Dee will go by Donald, Mikey will go by Miguel and Raph will be... Um, Raph?" Leo said as Raph pat his head.

"Now, any more questions?"

"Yeah, I have a question. What are we gonna watch anyway?" Donald asked as Sophia just smiled mysteriously.

"The movie you are all gonna watch is about the future of these three as well as yours." Sophia said as she pointed to the three turtles wearing the iconic blue mask.

"Also hope you like musicals. Let's start!" Sophia disappeared in a flash of light and the lights dimmed and the screen came to life...
