Comix Zone it's a video game developed for Sega Mega Drive in 1995 from Sega Technical Institute. The game is a fun mix of action and fighting games and is set within a comic.
An original solution that tells the story of Sketch, 
a comic artist who on a stormy night, while working on Comix Zone, is transported inside his comic. A bolt of lightning struck outside his apartment causes the Comix Zone's main villain, the mighty mutant Mortus, to make the reverse journey and into the real world.
Mortus intends to free himself and destroy Sketch, just as the artist did with the diabolical creature. Within the comic, Sketch meets General Alissa Cyan, who believes him to be a superhero ("the chosen one") who has come to save their post-apocalyptic world from the evil of the Mortus and the alien invaders. Alissa just sends him on a mission, and the adventure begins. Before moving on to the tricks, a tip: if you find this game in some flea market or online, obviously at an acceptable price, grab it. You will not regret it!
