Doom Beastiary

Doom Beastiary (sic) was a website created and hosted by Nick Baker (NiGHTMARE). It contained general information about Doom monsters (name, health, speed and attacks), but also featured numerous fan-created monster ideas (each represented by a single sprite, and sometimes proposed in-game statistics). The site had not been updated since December of 2003, and went offline sometime between January and June in 2017.

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

Daniel Gimmer (Tormentor667) created his Realm667 Doom Beastiary in 2007 as a monster resource site and an homage to Nick Baker's Beastiary.
