The Ninja Turtles patrolled the rooftops of New York on a seemingly calm night, but they did not let their guard down. Leonardo, with his ninjatō, led the formation, followed by Raphael with his sais, Donatello with his bō, and Michelangelo, always with his nunchakus at the ready. Suddenly, a group of Krang appeared, attacking without warning. The turtles reacted instantly, each using their weapon with precision and skill. Leonardo cut the Krang down with fluid movements, Raphael struck with brute force, Donatello used his bō to keep the enemies at bay, and Michelangelo disarmed the Krang with swift, accurate blows.

After a fierce battle, they managed to defeat the Krang, their metallic bodies scattered across the rooftop. However, amidst the chaos, a cylinder of mutagen was thrown into the air, spinning uncontrollably before falling towards the street below.

The turtles were horrified to see the cylinder heading straight for a teenage girl walking carefree down the sidewalk. “No!” Leonardo shouted, but it was too late. The cylinder crashed to the ground, splashing the mutagen everywhere.

With their hearts in their throats, the turtles watched from the roof, expecting the worst. But to their amazement, the young girl did not turn into a mutant. She stood there, completely unharmed and… human. As if nothing had happened.

The teenage girl, seeing the cylinder on the ground, picked it up, looked at the green liquid inside, and without a second thought, took a sip, believing it to be some kind of soda. The turtles couldn’t believe what they were seeing.

“Did she just…?” Donatello muttered, incredulously.

“And nothing happened to her…” Raphael said, still in shock.

“She’s just like April,” Michelangelo commented, impressed.

Leonardo, finally coming to his senses, said in a serious tone, "She's immune… just like April."
