A tengu is a minor demon that appears in NetHack. Its corpse is valued by many players, as it has a chance of granting teleport control (but can also grant teleportitis). Encountering tengus can be quite annoying as they extensively teleport themselves during combat after hitting. Unlike other minor demons, they are not susceptible to silver damage.
The wizard quest home, locate, and end levels often are pre-populated with several tengu. The Knight quest levels also generate many random i, including tengu, and they can be easily farmed with the abundance of magic traps surrounding the Isle of Glass.
Tengu are easier to kill in a no-teleport zone, such as Sokoban. In addition to reverse genociding them, Knights may also consider genociding quasits; as this makes up most of the monsters generated on the quest levels, this increases the chances of minor demons spawning, including tengu, which allows them to be farmed on the home level.

Tengu are demons or spirits in Japanese folklore. They are portrayed either as humanoid birds or having long noses. They are usually represented by characteristic fierce red masks with very long noses.
The tengu was the most troublesome creature of Japanese
legend. Part bird and part man, with red beak for a nose
and flashing eyes, the tengu was notorious for stirring up
feuds and prolonging enmity between families. Indeed, the
belligerent tengu were supposed to have been man's first
instructors in the use of arms.
