Ep 23. Parasitica

In the episode "Parasitica" of Teenage Mutant Ninja Turtles (2012) season 1, the Turtles are on a mission to stop a parasitic alien race known as the Kraang from taking over New York City. The Kraang are using mind-controlling parasites to infiltrate and take over the bodies of humans in order to carry out their plans.

The Turtles discover that a Kraang portal has opened up at a hospital, which is likely the source of the parasitic invasion. They venture into the hospital to investigate, but are quickly met with hosts who have already been taken over by the parasitic Kraang. The Turtles struggle to keep the parasites away from them, but some of their team members get infected themselves. Leonardo, Raphael, and Donatello are able to fight off the mind-controlling parasites, but Michelangelo falls victim to the Kraang invasion.

Now under the control of the Kraang, Michelangelo is sent out to capture his brothers and bring them to the Kraang. The Turtles are forced to fight Michelangelo and try to find a way to remove the parasite from his body before it's too late. Meanwhile, they also have to battle against the Kraang's army of robots that are trying to take over the hospital.

The Turtles eventually come up with a plan to destroy the Kraang portal and rid the hospital of the parasitic invasion. However, they still need to find a way to save Michelangelo. They come up with a risky plan to remove the parasite from his body, but it will require them to enter his mind and physically remove the parasite from his brain.

The Turtles are able to successfully remove the parasite from Michelangelo's body, but not before it temporarily turned him against his brothers. The episode ends with the Turtles continuing their fight against the Kraang and their invasion of New York City.

Overall, "Parasitica" is an action-packed episode that showcases the Turtles' determination to protect their city from a dangerous alien threat. The episode also highlights the importance of teamwork and loyalty, even in the face of mind-controlling parasites that can turn friends against each other. This episode is a must-watch for fans of the Teenage Mutant Ninja Turtles franchise.
