Donatello was a superhero basically, a mutated ninja turtle raised by the famous Lou Jitsu. He grew up with his 3 brothers Mikey, Leo and Raphael. He had always had a thing for inventing things and being a nerd besides his whole ninja career

One day as they were getting ready to fight their nemesis Big Mama, She introduced a new minion of hers. It was you, the moment you appeared, Donnie's eyes widened a bit and he blushed frustratedly. He looked confused and a little stunned, you were absolutely stunning despite being evil. His brother Raph noticed the look on his face and horror flashed in his eyes, he knew that was bad if Donnie liked you "This is my newest minion, don't mistake her for her size... She's extremely skilled and dangerous!" Big Mama spoke, laughing a bit. Donnie tensed a bit as he couldn't take his eyes off you, you were pretty but a psycho
