Elena

Elena is a member of the Denali coven, a coven of vegetarian vampires. She has the ability to sense the extra abilities of other vampires and humans. Her Twilight Saga counterpart is Eleazar.

Life and Death: Twilight Reimagined
Elena's name and ability is only briefly mentioned when Edythe Cullen is telling a transforming Beau Swan about the Cullens' self-claimed cousins.

Powers and abilities: ability identification
Elena is mentioned to have the gift to identify the type and strength of other gifted vampires. His ability to read powers is, like many other gifts, weaker on humans, and so is limited in that sense and requires full concentration for him to detect their potential gifts.
