Leviathon

From Hellgatewiki.com

This monster has only been seen in old concept art on the wall at Flagship Studios, and never in the game. The names on the shots are different, but the artwork is identical.

Name: Leviathon
Caste: Beast?
Rank: Lesser Demon
Subtypes: Leviathon, Burning Fiend
Special: Unknown. Flight, obviously.

Nothing is known about this monster other than what's seen in the concept artwork. They look small and harmless, but have never been seen in the game, and since we've seen most every low level monster, there is some speculation that maybe these sparrow-looking birds are actually more like rocs, large enough to carry off your character and the car they rolled up in.
