Summary
“You were supposed to be my enemy!” Usagi’s voice cracked, raw with emotion, as he stared down at Leonardo. The blue-masked turtle’s blood stained the cold floor, a glaring contrast to the vibrant blue of his mask.
You’re a fool to think you can change me,” Usagi hissed, his voice trembling despite his attempt at a harsh tone.
He aimed to strike, his katana raised high above Leonardo's head, who knelt before him, disarmed. But Usagi's' hand trembled. Leonardo made him tremble.
“I don’t want to change you,” Leonardo replied softly, his gaze unwavering. “I just want you to see…to see that there’s another way.”
Or,
Yuchi was taken in by the Shredder and molded into a ruthless weapon in exchange for revenge against those who wronged him. He had heard of the turtles from Karai but was unsure of their role with the Shredder.
Now, he was finally unleashed, Usagi is driven by a mission he doesn't fully understand but was determined to complete. He would not let Shredder down. He would not fail. That was, until he met Leonardo.

Summary
Yuchi gets too curious and touches a mysterious artifact—the next thing he knows, he’s in a strange world full of outdated technology and 'weird magic rectangles'.
Chaos ensues when he tries to talk to humans and gets caught up in a police chase, attracting the attention of 'evil' kappa. (The turtles.)
During the fight to restrain Yuchi and discover who he is, Leo offers his sword as a peace treaty to end the battle.
Yuchi freezes, turns bright red, and stammers, “D-Did you just propose to me?!”
Leo blinks. “Wait, what?!”
Congratulations—Yuchi is now accidentally married to a ninja. And he hates ninjas.

Summary
Raised by the Foot Clan, Leonardo becomes a cold, precise, and deadly ninja—loyal only to the mission.
When he's paired with Yuichi Usagi, a free-spirited and annoyingly calm fighter from Japan, Leo is instantly irritated by his carefree attitude.
Despite the tension, something shifts and Leo finds himself drawn to Yuichi’s warmth.
But everything changes when Leonardo fights a trio of mutant turtles— that strangely resembling him. One steps forward, eyes wide with disbelief.
“Leonardo… is that you?”Their words hit like a blade to the chest, and suddenly, Leo’s past isn’t as buried as he thought.

Summary
This wasn't how Pure Vanilla Cookie had intended his confrontation to go with the Beast of Deceit. He hadn't intended to become so emotionally intertwined with Shadow Milk Cookie. More over, he certainly hadn't planned to accidently press the two halves of the Soul Jams together. What a mess his short sightedness had created this time.
or, Pure Vanilla Cookie gets shoved back in time by billions of years. Back before the Beasts had defected and corrupted, back before the modern era. He has a rare chance now, one he cannot afford to falter and lose. Sure he had out maneuvered the Master of Deceit, but how can he possibly hope to win against the embodiment of all Knowledge?
