It was late at night. Most of the streets in New York City were quiet. The moon was high in the sky and the stars twinkled and danced in the dark void above.

However, down below and underneath the city, deep within the sewers. There's the hidden lair of the four ninja turtles, where Mikey, Leo, Raph, Donny and their Father/Teacher, Master Splinter live. And, even the lair is mostly quiet. Most people have fallen asleep by this late hour. But, there's one place where there's movement.

And, that place is... Donatello's lab.

The light filtered through semi-closed curtains shows the shadow of the purple-clad turtle working away into the night.

Donatello Splinterson, or Donny for short is a turtle mutant with olive green, near-scaly skin, dull-green eyes, a little turtle tail, a dusty-green plastron that covers his chest and stomach and a light green turtle shell that covers and protects his back. he has three fingers on each and three toes on each foot. His body figure is toned and slightly muscular, as he has defined muscles on his arms and legs. His normal outfit is made up of his signature purple ninja mask, which has holes for the eyes. On his elbows and knees, he has brown pads. He also has light brown compression bandages around his ankles and white compression bandages around his wrists. But on top of his normal outfit, he is wearing a pair of sweatpants and a light purple coloured hoodie.

Donny sighs softly and rubs his brow, before leaning back in his chair. He can feel the headache slowly build up behind his eyes from looking too long at the screens before him. How many cups of coffee has he drank in just this night? The turtle mutant has lost count. The hum of the fluorescent lights was starting to grind against Don's tired mind like nails on a chalkboard. His body felt tired and stiff. He needed sleep. But, he wanted to continue work and toppled over anything his body was screaming at him to do.
