Marten Skunk is a character created by Furfragged. He is a young anthropomorphic male skunk of similar age and build to that of the character Sino.

In the video game HUD style of Furfragged's art, Marten often takes the role of "Player 2". He first appeared as a player 2 in a series of Frag's Exhibitionist pieces starting on August 1st, 2015. At the time his name was Smoke Skunk. The character would later be repurposed into a series of solo Game Overs with the premise that he is a straight skunk who suddenly finds himself in a place full of predatory gay men who wind up seducing him into gay sex such as a Gay Bar or The Folsom Street Fair. This version of Smoke Skunk, now referred to as Marten Skunk first appeared on April 6th, 2016.

Marten was mildly popular at one point but Furfragged stopped using him due to the fact that as far as his characters go, he is incredibly similar to Sino down to even having a similar outfit.
