Kenfis

Kenfis (Type F-1) is a creature that appears in Sega's arcade rail-shooter The House of the Dead. They appear to be genetically-engineered animal hybrids with the bodies of dogs that possess large bat-like wings on their backs. Despite having wings, Kenfis cannot fly and attack by running and pouncing at the player. They come in various colours which are indicative of how much gunfire they can take before dying.
