Aura of Smooth

Aura of Smooth is the field that Mary Sues and Self Inserts generate which makes canon characters bend to their will.

Aura of Smooth is known to be transferable, if temporarily, by ingesting parts of a former Sue without "stripping" the Aura first-- such as a cut of meat, or even Sue blood (if large enough amounts come into contact with the bloodstream).

When found in Water, Aura of Smooth lowers inhibitions and/or gives the person who consumed it a higher will power than normal. Presumably, anyway. Just be careful with it.
