Umber hulk (monster class)
The umber hulk is a monster class in NetHack represented by an uppercase U glyph (U). Umber hulks are designated internally by the macro S_UMBER.[1]
The umber hulk is the only member of the monster class.[2]
History
The umber hulk first appears in Hack for PDP-11, a variant of Jay Fenlason's Hack, and is included in the initial bestiary for Hack 1.0.

SLASH'EM
SLASH'EM adds the water hulk, a type of hulk that has the same attack dice, but can also swim and is only found in Gehennom.
