Dimension X, thousands of years in the past.
"Alright bros, this is it." Michelangelo said as all four turtles ventured through the Dimension X wasteland. "Renet told me she would be gone to get help across the multi-verse. So we're on our own for now."
"Sounds like a plan. But where exactly do we begin?" Donatello said in response as he adjusted his Dimension X breather. All the turtles had them as they were fully prepared for their mission to fight the Kraang.
"Renet just told me telephatically about a Mutagen Bomb that the Kraang are making at this point in time. That's where we gotta go bros." Michelangelo said as he focused his mind, being the genius that he was in this parallel universe.
"Looks like genius Mikey is here to stay for now." Raphael said with a hint of sarcasm in his voice.
"Be careful ninjas." Leonardo said as he tightly held one of his Katanas. "There's no telling what might be here."
Just as Leonardo said this however, a rapid succession of laser fire flew over their heads, sending the turtles into shock. They ducked for cover immediately and hid under the vegetation of Dimension X crystals, as the fire continued.
"Triceratons! Attack the Kraang!" An individual on one of the warring factions said as the wasteland turned into a battlefield.
The turtles were only able to watch from a safe distance, as it was too dangerous to venture out with only the four of them to face two entire armies. The turtles were not even sure if they belonged in this war. Sure, the Kraang were clear enemies to them, but the Triceratons weren't allies in their eyes either, having destroyed the entire Planet Earth at one point in time.
"So, what do we Leonardo?" Raphael asked as the turtles continued to duck under cover.
"We make a run for it. We're too outnumbered to make a difference here." Leonardo said in response as all four turtles stealthily made their way away from the heat of battle.
The turtles managed to get away safely, but it wasn't long before they were lost in the vast Dimension X wasteland again. With nowhere to go and their food supply running out slowly but surely, it seemed to our heroes that they were going in circles in a place that looked the same throughout.
"Well, there goes our last bottle of water." Raphael said as he took one final sip, leaving the turtles without any source of nourishment.
Aimlessly, They continued to wander in search of their vaguely defined objective, but to no luck. Eventually, they collapsed one by one. Leonardo was the last one to remain standing in the middle of the harsh Dimension X environment, and before he fell unconscious, saw a multitude of figures approaching him and his brothers. Helpless, he collapsed as well, hoping that the figures had good intentions.
A few hours later.
"Where am I?" Leonardo asked as he slowly observed his surroundings. He was in a strange but familiar place. But what mattered most of all that Leonardo felt nourished and saw his brothers safe, sound asleep next to him.
Then again, he saw the figures from before standing infront of him. They were the Utroms.
"Bishop?" Leonardo asked.
"Who are you? How do you know who I am?" Bishop asked the turtle, confused himself.
"Its hard to explain. We know each other, but not yet." Leonardo said as he slowly stretched to get rid of the slumber in his body "Me and my brothers are actually from the future."
"So you four are time travellers. What else do you know?" Bishop asked him in a friendly but cautious tone.
"That you are the Utroms, fighting against the Kraang hive mind after one of your scientists discovered Mutagen." Leonardo remarked. "We're here to help, though we don't exactly know how yet."
"Are you sure we can trust him?" One of the fellow Utroms asked Bishop.
"In times like this, we can use all the help we can get against the Kraang and the Triceratons." Bishop said with a smile on his android body's face as he assured his fellow Utroms of the turtles' innocence.
Slowly but surely, the other turtles woke up as well. They were immediately treated to food and water by the friendly Utroms, and felt much needed relief after having spent hours in the harsh Dimension X landscape.
"This is amazing." Donatello said as he downed some of the food.
"Even better than Pizza dudes!" Michelangelo said as he couldn't help himself enough to the mysterious but delicious delicacy that the Utroms offered to them.
"What is this stuff?" Raphael asked.
"Kraathatrogon Flesh." Bishop said in response, having a relatively emotionless look on his face, as if this was a regular norm and occurrence in his homeworld.
One by one, the turtles stopped eating their food without saying anything. Their expressions were one of horror and denial.
"I think we're full." Michelangelo said in a hushed tone as he broke the awkward silence.
"In honour of Mortu!" Bishop said as he handed the delicacy to his fellow Utroms.
"Mortu?" Leonardo asked, instantly becoming more curious than disgusted at this point.
"You're telling me you've never heard of our great King?" Bishop asked the four turtles.
"We have come to know a lot about the Utroms over the years, but to know you have a King, that is news for us." Donatello said in response.
"He may no longer here with us, but Mortu lives on in the hearts of all Utrom Kind." Bishop said, his tone of voice becoming slightly more sad than before.
"What happened?" Raphael asked Bishop.
"It was Kraang Prime. He killed our King, and that allowed him to brainwash most of us." Bishop said. "Without Mortu on our side, we are only a mere shadow of our past selves, hiding all the time. He truly was a great king, bringing a new era of peace and prosperity after we had been a race of war and blood in the past. But it was never enough for some who couldn't let go of the past."
"It must've been a tragedy for Kraang Subprime to betray you." Leonardo said as he listened to Bishop's story.
"Kraang Subprime?" Bishop asked, completely confused.
"You mean you don't know about." Leonardo said, but before he could finish, another Utrom entered the ship that he and the other turtles were on.
"Knight!"
"Bishop!"
The two Utroms embraced, to the delight of all the other Utroms at the council.
The turtles however, were horrified upon seeing that Kraang Subprime, formerly known as Knight, was still roaming freely among the Utroms.
"Turtles, meet my brother." Bishop said as the turtles reluctantly greeted the secretly traitorous Utrom, one by one.
"Where have you been, brother?" Bishop asked Knight.
"Spying on the Kraang, they've been up to no good." Knight said in response.
"You've been risking your life on a daily basis. You know I could lose you if you go out too much." Bishop said as he affectionately placed one of his tentacles over his brother's body, since both of them were now outside of their android bodies in the comfort of the ship.
The Utrom Brothers continued to converse among each other and with the rest of the council, but the turtles could only look at each other wide-eyed in silence, knowing that they had to show Bishop and the Utrom council the truth about Knight before it was too late.
