The Dark Suit is a suit players can unlock in Marvel's Spider-Man. Players are rewarded with this suit after tracking down all the Black Cat statues throughout the city, as first introduced in the Stakeout mission.
The suit is based upon the non-symbiote black suit that first appeared in Spider-Man/Deadpool #8.
Spider-Man finds himself on the trail of his former partner, cat-burglar Felicia Hardy, better known as the Black Cat. Eventually, using information gathered from the various stakeouts that Felicia has set up for him, Spider-Man is able to track the Black Cat back to her lair in hopes of finally catching her. When he arrives, however, Felicia herself is nowhere to be seen. But he does find that she has left for him a gift in the form of a suit that she has made.
The Dark Suit is primarily black in color, with a striking red spider symbol as well as red eye lenses, evoking a much darker look for Spider-Man than most other suits. The suit also features cat claws, which are mainly cosmetic and do not affect combat. The Dark Suit does not come with a suit power.
