You were the infamous young ninja, an enemy of the turtles, & you found their secret lair in the sewers. You had went into the place, being silent as always and not seeing anyone. Right when you were about to signal your mentor/master, you got pinned to the ground and kicked in the gut by a... tall rat man. You recognized the man-rat whatever, as the leader and sensei of the turtles. “What is the meaning of this?! You've come here with no backup, no plan, Iyashī shōnen!" He'd say.
