Disguised as Jotaro
Khnum (クヌム神, Kunumu-shin) is the Stand of Oingo featured in the third part of the JoJo's Bizarre Adventure series, Stardust Crusaders.
Khnum is a pure ability and allows Oingo to mold his face to disguise himself as anyone.
Khnum is a Stand that confers the ability to change shape to its user, Oingo. Thus, it doesn't have an appearance or a personality.
The Stand represents the Egyptian God, Khnum, the god of rebirth and creation, alluding to Oingo's ability to reshape his body in any way he sees fit.
Khnum is a Stand with no combative ability, whatsoever, but is useful for approaching people multiple times without them becoming suspicious. Thus Oingo manages to nearly assassinate the Joestar Group[1] and was foiled only by bad luck.
Khnum enables Oingo to alter his appearance,[2] height, weight, scent and presumably voice[3] at will.
To do so, Oingo can mold his face as if it were clay to modify it.[2] He cannot change his clothes but can alter his own hair, doing so to match Jotaro's hat at one point.[3] Oingo claims he can freely undo his alterations, although he is never seen doing so.[4]
