Donatello is a character appearing in the Teenage Mutant Ninja Turtles: Saturday Morning Adventures. He and his brothers are the Ninja Turtles of an alternate dimension, also known as the "Nega-Turtles".
History[]
In a parallel world where Michelangelo was never mutated, Hamato Yoshi became despondent and depressed. He raised the three remaining Turtles as a more malicious, hard-lined ninja clan. They were awarded a home in the sewers by New York City's mayor, Shredder, but they secretly plotted to overthrow him in order to install Yoshi as the city's leadership.
After Michelangelo discovered a magic ring, the Genie within granted his "needed" wish, transporting him to the alternate world where he was not around. Michelangelo came across Hamato Yoshi, confusing him for his Splinter. Yoshi assumed him to be an impostor of his students and attacked him. Michelangelo ran away, but was cornered by this world's Turtles. The "Dark" Donatello called Mikey a jerk and demanded to know what he was doing in their lair. They took turns attacking Mikey, but he dodged them, so they rushed him together and managed to knock him out. With the masks over their faces, their voices were garbled, so at one point Leonardo called Donatello "Raphael" and had to be corrected. Genie in a Bauble, Baby!
