Doom Beastiary

Doom Beastiary (sic) is a website created and hosted by Nick Baker (NiGHTMARE). It contains general information about Doom monsters (name, health, speed and attacks), but also features numerous fan-created monster ideas (each represented by a single sprite, and sometimes proposed in-game statistics).

The site is inactive, having not been updated since December of 2003. Daniel Gimmer (Tormentor667) created his Realm667 Doom Beastiary in 2007 as a monster resource site and an homage to Nick Baker's Beastiary.

Some of the monster concepts have been turned into fully developed custom monsters in the ZDoom Monster Resource WAD.
