Enemies Revisited
When I started my adventures as Ghost Archer the villains presented in the Enemies books where state-of-the-art.  A lot has changed in the ensuing years but my old enemies have remained frozen like a fly in amber.  Originally I was just going to just convert this characters to 5th Edition without change but then I took a look at them and decided to fill in the twenty plus years since they were created.

From European Enemies
Huntsman of the Black Forest: rival to the Master of the Wild Hunt, and immortal enemy.
Hounds of the Huntsman: the Huntsman's pack.

From Enemies III
Bison aka Buffalo: U.S. Army research project gone bad.
Dark Angel: reluctant emissary of Death.
Demonfire: a demon's daughter.
Green Knight: the headless warrior.
Mechassassin: one of the first of Ghost Archer's foes.
Monster: Evil Incarnate.
