This paper toy is the Venom, based on the game Venom/Spider-Man: Separation Anxiety, the papercraft is designed by Paper Toy Adventures. As a symbiote, Venom is a combination of both human and alien organism. He has all of Spider-Man's generic abilities (web-swinging and wall-crawling), but unlike Spider-Man, his combat moves are primarily based on raw power. He also takes less damage per hit than Spider-Man.
Venom/Spider-Man: Separation Anxiety is a side-scrolling beat 'em up video game and sequel to Spider-Man and Venom: Maximum Carnage, released for Sega Mega Drive and Super NES and then ported to PC, in which one or two players could team up as Spider-Man and Venom to defeat the evil symbiote Carnage. The game boasts a large number of thugs that the player has to defeat: heavily armed Jury and Venom's symbiote children.
Of particular note is that the title is misleading - the plot of the comic book series Venom: Separation Anxiety involves Venom's five symbiote spawn attempting to force Eddie to help them communicate with their own symbiotes. The events of the game more closely follow the events of Venom's first limited series, Venom: Lethal Protector.
