A weapon accessory in the likeness of a human, animal, mythical, or other creature, or a part of the creature, has a longitudinal passageway adapted to allow a projectile to exit the muzzle through the accessory. The projectile passageway opens through a mouth, eye, nose/nostril, or ear structure. Additional apertures selected from these structures, other than the one selected for the projectile exit, may be in fluid communication with the projectile passageway for directing exiting gasses in desired directions, for example, for a muzzle brake. The additional apertures preferably extend generally upward at an angle to said projectile passageway, including straight upward, upward and forward, or upward and rearward, and may also extend to a left or right side. Upper and lower jaws of the creature may be shaped or sized to direct gasses and hence light/flash in desired directions, for example, for flash suppression.
