Groaners appear as very large, hairless, demonic dogs with rotten brown skin and a very large set of jaws. The beast's physique is quite synonymous to the greyhound dog breed, which also supports the Groaners' intimidating speed. They are clearly emaciated, making them appear starved or even dead as a result, albeit this fails to take away from their huge size and constant risk on the streets of Silent Hill.
One of the more common enemies of the game, they are sensitive to sound and will react to a gunshot or Harry Mason running nearby. They only appear in outdoor areas while he is trying to move to a different building, and are easily avoided if precautions are taken.
Groaners attack Harry on sight, or as soon as he makes enough noise to draw their attention. They move very rapidly and often sprint circles around their prey, jumping up to deliver a bite or lunging full force at Harry. Due to their small size and agility, hitting them with a melee weapon can be challenging. As a result, firearms are the best method to dispose of them. However, not drawing their attention or avoiding them is preferable. Panting and the light tapping of claws on pavement often signal their presence.
The image of a large dog, which Alessa Gillespie has a strong dislike for, is the basis for this creature. Alessa was often frightened by barking dogs as a child, and grew to fear them in general.
