Who's cheese?
Blaine may have escaped with Cinnamon and destroyed all of his research, but that wasn't going to stop team rocket, and he couldn't erase everything. When Cinnamon was born Blaine excitedly called up Giovani and divulged two things he could never take back- that he had succeeded by using his own DNA, and that the Mewtwo was "just a baby."
Within 6 months Team Rocket had rebuilt the necessary machinery and created another Mewtwo, this time involving experiments with aging. This one was modified to grow 6 times faster than it should, to minimize the baby phase that in their eyes had ruined the first attempt, but they couldn't have predicted the health issues this rapid growth would cause. It was an utter disappointment.
Cheese recently escaped captivity with the help of Limburger, an Alakazam he befriended in the lab, and they found their way to Mr. Fuji.
Cheese tries to make the best of his life with a positive attitude and lots of jokes, but falters on the days where he can barely move. He wishes he could do more to help Mr. Fuji's Team Rocket Rescue efforts, but is also content uplifting the other rescues, especially his "little bro" Cubert. He's currently relieved that Maple is hibernating instead of reminding him he's a freak that shouldn't be alive every chance she gets.
