Keno

Keno is an American pizza delivery teenage boy who is friends with April since he's been delivering pizzato her for some time in Teenage Mutant Ninja Turtles II: The Secret of the Ooze. His backstory is unknown and he eventually becomes friends with the Ninja Turtles. He first met them when he was taking some pizza to April when he saw large vans near a store and went over to see what was going on, only to find out that gang members were robbing the place. Keno ordered them to stop but they mocked him saying he's a night security then he attacked them but soon finds himself greatly outnumbered. The Turtles arrived just in time. Keno was shocked at their appearance but got a good enough look at them to recognize Raphael's foot popping out from his hiding place while delivering a pizza to April's. Splinter told him their story of how they came to be and Keno told them about these ninjas he heard about, The Foot. Raphael and Keno infiltrated their HQ against Splinter's wishes and fought a large group of Foot Ninjas in the junkyard. Keno escapes to inform the others, but the group is lead into a trap and are pitted against Tokka and Rahzar.

He is impatient though just like Raphael. Splinter did give him some advice at the end of the movie but Keno was rushing to go help the Turtles fight Shredder and the Foot. Keno knocked the ooze out of Shredder's hands. Keno is not in the first or third movie at all. Its unknown what happen to him after the second movie ended, and he has yet to appear in any other TMNT movies, cartoon, TV series, comic book, or video games since.
