Teenage Mutant Ninja Turtles: Paranoia

Humankind learns about yokai and together the two races start working towards peace. Somewhere along the line Hamato Yoshi and Draxum start working together to create the mutagen, which originally was supposed to benefit both races…however, it obviously does not go as intended.

During the big ceremony showcasing the mutagen, things start going run. The mutagen, which was supposed to act as a temporary way for the two groups to live in each others shoes, instead seems to be much more than that, as evidenced by Hamato Yoshi’s painful looking mutation onstage. As the crowd panics, the mutagen canisters explode, drenching many people in the crowd. Splinter, now a rat, grabs four random turtle test subjects who were also mutated and runs. The whole thing is initially blamed on Draxum, who conveniently disappears before anyone can prove it is-or isn’t-his fault. Only later, once the chaos has waned, do officials realize both parties responsible for the mutagen have disappeared, as well as four of the test subjects and many panicked civilians.
