A tengu is a minor demon 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. It is easier to kill them in a no-teleport zone such as Sokoban. 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 popular Japanese demons/spirits. They are either portaged as humanoid birds or having long noses. In Japanese folklore, they are usually represented by characteristic fierce red masks with very long noses. Most people have seen portrayals of tengu, even if they didn't know their name.
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.
