The Imp is the first hell monster encountered in Doom. It is the most common monster in the game, along with Possessed Humans. They are small, brown, agile creatures with orange eyes, more similar to the typical idea of an Imp rather than the more humanoid versions from Classic and Doom 3. Imps are thought to be a lower form of the Summoner. The Imp doesn't get along with higher-ranking demons like Barons of Hell, Hell Knights or Mancubi, which often leads to random fighting in Hell. As a result, the evidence indicates that there is unfairness among the legions of Hell.
