Mothman

Games
The Mothman sightings were a basis for an interdimensional alien race in the conspiracy role-playing game Dark•Matter, a campaign setting for TSR's Alternity SciFi RPG. The Mothman subsequently played a major role in the plot of the adventure supplement titled The Killing Jar, and appeared as a monster in the d20 Menace Manual, known as the "Mothfolk".
A less menacing version of the Mothman appears in Shin Megami Tensei III: Nocturne for Sony PlayStation 2. However, the database in the game still states that it is the same as the one sighted in West Virginia.
In Castlevania: Dawn of Sorrow for the Nintendo DS, Mothman is one of three hidden cryptozoology-based monsters, appearing as a furry black heart-shaped creature with wings and large eyes (generally resembling the eyewitness sketch). The same monster appears as a regular enemy in Castlevania: Portrait of Ruin.
