Fishers from Outside

Fishers from Outside—named so due to their tendency to swoop like a fishing-bird—have a quasi-avian form, with scales instead of feathers. They also have one leg, a glaring Cyclopean eye, and a hideous, hooked, fang-lined beak.

In the RPG...

Despite their odd appearance, the Fishers are fairly standard monsters, though quite deadly. They have 9-point armour—so most guns will be ineffective against them—and they can attack with either their beak or talons for an average of 7 damage, or grasp and crush them for an average of 3 damage per round that the victim is held. The victim can free themselves by opposing the Fisher's STR, though an average Investigator only has a 14% chance of achieving this. Then there is also the fact that they will be lifted up into the air, so if they do break free, they will then fall to the ground, which—depending on height—could potentially kill them.

In a video game...

Besides their appearance, there's nothing particularly unique about the Fishers, so I'm going to say they could work in a game, though would be a pretty generic enemy.

In a film...

As I said above, I don't think the Fishers are particularly interesting, so I wouldn't be too eager to see them in film.
