## Doppelganger
*Shape-Shifting Infiltrator*
- **Habitat.** Underdark, Urban
- **Treasure.** Individual
Doppelgangers are supernatural beings with the ability to shape-shift into any humanlike form. Their mind-reading abilities aid them in creating near-perfect disguises and plucking secrets from unguarded minds. Occasionally, doppelgangers use their shape-shifting ability in more overt ways, transforming into unsettling forms to frighten foes.
A doppelganger's agenda might relate to its mysterious magical origins or to more mercenary goals. Roll on or choose a result from the Doppelganger Deceptions table to inspire a doppelganger's plot.
