These are my nephews Mr. C and Mr. K during Halloween. Mr. C is Raphael from the Teenage Mutant Ninja Turtles and I'm pretty sure Mr. K is Sub-Zero from Mortal Kombat. Though I think he probably just wanted to be a blue ninja. Mortal Kombat is a extremely violent video game, so I know his parents wouldn't let him actually have the game. Funny enough, I was about his age when the first few Mortal Kombat games came out. We played it in the arcade at the movie theater and on the Sega Genesis.
