Alfredo is a person appearing in the 1987 TMNT cartoon episode The Case of the Killer Pizzas. He is of Italian origin, with a thick accent, and has dated Irma., with less than satisfactory results.
He is playing the accordion at a pizza prize-giveaway when he spots Irma and attempts to woo her once again. Irma flees from him (having declared that his mustache was bigger than his brain), but Alfredo doesn't seem to get the hint.
April decides to rescue Irma by declaring that Alfredo should meet Irma's family: Papa Leonardo, Uncle Donatello, Cousin Raphael and Auntie Michelangelo. The Turtles all extend their hands out of the alley. Horrified at the thought that any child they had might be green, Alfredo flees.
