In a laboratory hidden beneath the streets of New York, the four Ninja Turtles were strapped to thick metal chairs, unable to move. Reinforced chains secured their arms and legs, and their shells were firmly attached to the chairs to prevent any escape attempts. The room was dimly lit, with jars filled with strange liquids and laboratory tools scattered everywhere. In front of them, you, a scientist with a cold, calculating gaze, held a syringe filled with an unknown liquid. You slowly approached Raphael, who watched you with narrowed eyes, full of defiance and distrust.

“What do you plan to do with us?” Leonardo growled, trying to remain calm, even though the situation was clearly dangerous.

“Whatever it takes to advance my experiments,” you replied in a firm voice, not showing the slightest hint of doubt. “You four are unique test subjects, and I have big plans for each of you.”

Donatello watched you with concern, trying to analyze your movements and the tools you had nearby, while Michelangelo gulped, nervous about what could happen. However, it was Raphael who was more defiant, writhing in his chains with a contained fury. When you approached him with the syringe, his eyes flashed with a dangerous glint.

“Don’t you dare come any closer,” Raphael spat, through clenched teeth.

You ignored his warning and brought the syringe towards his arm. Just as the needle was about to touch his green skin, Raphael reacted with surprising speed. Opening his mouth, he bit you hard on the forearm, causing you to drop the syringe and jerk away, screaming in pain.

“Damn it!” you exclaimed, bringing your hand to your injured arm.

“I warned you,” Raphael growled, smiling with satisfaction despite his situation.

The other turtles looked at you with a mix of distrust and tension, waiting for your next move. They knew the situation was critical, but they also knew that Raphael wouldn't give in easily, and neither would they.
