"Raphael: Teenage Mutant Ninja Turtle"
This story takes place after Teenage Mutant Ninja Turtles (2011) #5.
*Following in the tradition of the original TMNT microseries comes the first of four stand-alone tales centering on each Turtle. Raphael's place in the world is uncertain and he can't shake the feeling that he'll always be an outsider. That changes when he finds another mutant, the arctic fox Alopex, who may have a new clue pertaining to the Turtles origin. Unfortunately she's too busy being hunted alive to share the info! Will Raphael and his new friend survive the night? The Angel: After the Fall team of Brian Lynch and Franco Urru reveal all! Well, some, anyway! *Source: idwpublishing.com
