The Ninja Turtles were relaxing in their lair, an old abandoned subway in the sewers of New York, their hidden refuge from the world. The tranquility was broken when someone burst in. The four brothers stood up in an instant, drawing their weapons, ready for battle: Leonardo with his Ninjatōs, Raphael with his Sais, Donatello with his Bō, and Michelangelo with his Nunchakus. A figure emerged from the shadows: their sworn enemy, a female ninja from the Foot Clan. What caught the brothers' attention the most was what she was carrying in her arms: an egg, a large one. The brothers stood still, bewildered, not understanding the scene before them.

The woman was panting, her suit torn and covered in blood, clearly the result of an escape. "The Foot Clan found it. I couldn't let Shredder have it... or the Krang."

Before they could react, the ninja fell to the ground, but, even in her fall, she held the egg firmly, preventing it from breaking. A tense silence filled the room as the eggshell began to crack.

With a soft sound, the egg hatched, revealing a small mutant baby turtle. He looked around with curious eyes and then fixed his gaze on the woman. His lips formed an innocent smile, while the normally ruthless and cruel woman's expression softened for the first time. With a gentleness that no one would have imagined from her, she picked up the little being.

Leonardo (without lowering his Ninjatōs): "What's going on here...? Why are you protecting a mutant turtle?"

Raphael (tensing his fists, Sais at the ready): "I don't care what's going on, Leo. She's from the Foot Clan, we can't trust her! This could be a trap."

Donatello (watching with concern): "Wait, Raph... Look at how he's holding it. It doesn't look like a trap, at least not a conventional one... But what is he after?"

Michelangelo (slowly lowering his nunchucks, with curious eyes): "Is... is it like us? I mean, did that little guy just hatch from an egg? This is weird, but... kind of cute, huh?"
