Supernatural Concealment

Supernatural Concealment is the power to hide oneself from anything, including Angels, Demons, etc.  This can also be used to shield them (or true form) from creatures with Supernatural Perception (i.e,Edgar was able to mask his presence to take two Angels by surprise.)

Characters with this ability

 * Eve- Eve was able to conceal her presence from any angel, forcing the winchesters, Castiel and Bobby to rely on a monster for her whereabouts.
 * Jesse Turner- According to Castiel, Jesse is hidden from angels, demons and humans unless he wants to be found.
 * Leviathans- At least one high ranking Leviathan was able to conceal his true form from two angels which allowed him to take them by surprise to kill them.
