Hell knight

The Hell Knight is a monster introduced in Doom II. It is exactly identical to a Baron of Hell, except that it has half as many hit points, is palette shifted to have brown skin instead of pink, and has slightly different sounds (they are very similar to the Baron's sounds, but transposed to a higher pitch). The Doom II manual describes them as follows "tough as a dump truck and nearly as big, these Goliaths are the worst things on two legs since Tyrannosaurus rex". This was originally the description for the Baron of Hell.

Doom RPG
The Hell Knight appears in Doom RPG as a variation on the Baron of Hell monster class. As in the original, it is not as powerful as the Baron, but is more powerful than the new "Ogre" variation.
