The Air Screamer is a flying creature appearing in Silent Hill. The Air Screamer is the second enemy that Harry Mason comes into contact with, as one bursts through the cafe window soon after he observes the radio. It is seen before it is actually encountered, flapping past the cafe's window. The Night Flutter is its Otherworld variant.
Air Screamers also appear in the spin-off game, Silent Hill: Book of Memories.
Its appearance is similar to that of a pteranodon but with the usual characteristics of the series' manifestations. The creature stands roughly half the height of a human giving it a quite impressive wingspan.
Its name is derived from the high-pitched screeching noises it makes when attacking or attacked. Air Screamers' danger lies in their mobility. They attack by biting at Harry and slashing at him with their talons. They're fairly fragile creatures, although landing a blow with a melee weapon is very difficult. As such, firearms are suggested for shooting them out of the air. To conserve ammo, it's recommended to flee from these creatures whenever possible. Listen for flapping wings and/or squawking sounds warning of their approach. If damaged, they may fly away, although they may also circle back and attack Harry from a different angle. To evade their talons, it's a pretty effective method to alter the direction of Harry's course left or right just before they strike and continue running.
The Air Screamer is a manifestation of an illustration in one of Alessa Gillespie's favorite books, The Lost World by Sir Arthur Conan Doyle, which presumably depicted a Pteranodon; but the creature also has the torso and legs of a human person.
As well, a latter speculation could also suggest the Pteranodon-like beast can serve a second purpose: its elongated legs (the ancient reptile's were not believed to be as long) and reddish hue is associable to demons, dark icons of many religions who reside in Hell. Their demon-like physique and behavior can be representative of what Silent Hill is: a very hellish town.
- There is a scene in Stephen King's The Mist where a similar creature attacks the protagonists in a grocery store, similar to how the Air Screamer attacks Harry Mason inside Cafe 5to2.
- It is possible to encounter a large flock of Air Screamers on the bridge that leads to Central Silent Hill.
