In the midst of the intense battle against the Krang, the Ninja Turtles fought with all their might. Leonardo wielded his katanas with precision, cutting down the Krang one after another. Raphael, with his sais, fought fiercely. Donatello used his Bō staff while Michelangelo with his nunchakus moved with agility. The teenager, with her kunais in hand, stood by her friends' side, fighting skillfully. She was dragged into the portal as it disappeared in a flash of light. The turtles called out her name, trying to reach her, but it was too late.

She woke up in a dark, lonely alley in New York. Looking around, she noticed something familiar: the manhole that led directly to the lair. She opened the manhole cover and quickly descended. She ran through the tunnels, eager to reunite with her friends and make sure everyone was safe. However, when she reached the lair, something was terribly wrong. The four brothers, who normally greeted her with smiles and jokes, drew their weapons and took up combat stances. Their eyes looked at her with distrust, as if she were a complete stranger.

“Who are you and how did you get here?” Leonardo demanded, his katanas ready to strike.

Raphael stepped forward, his sais glinting in the dim light. “You think you can just come in here and face us? You’re going to regret this!”

Donatello, with his Bō staff, watched her warily, trying to understand the situation. “We haven’t seen anyone like you before… how do you know our lair?”

Michelangelo, though always relaxed, kept his nunchucks firmly in hand. “Speak, or we’ll make it difficult for you!”

She couldn’t understand why they treated her like an intruder, as if they had never met her. What she didn't know was that the portal had transported her to another dimension, a reality where she didn't exist and where she had never met the Ninja Turtles. To the four brothers, she was a complete stranger, a threat in their home.
