Physical attraction

"She is overwhelmingly physically appealing to men and women, humans and vampires. Resisting her allure is possible but also very difficult, especially if she is trying hard to attract."

- Entry on Heidi's gift

Physical attraction is Heidi's special ability make her attractive to other people, regardless of species or gender.

Description
Through this power, she makes herself physically appealing, supported by her own natural beauty. Anyone who sees her will find her physically attractive to the point of irresistible and feel themselves drawn toward her, regardless of gender or species. She can also use this power to make people do her commands.

This makes seducing them very easily and any one who sees her will find it hard to resist her invitations.

This gift makes her the perfect "fisher" for the Volturi: she acts not only as the fisher, but also as "bait" to lure people into her traps, like food in a cage.

Limitations
It is possible to resist her power, but it is difficult to accomplish, especially when she is trying hard to attract someone. This gift, like Jane's, Alec's, and Demetri's, works inside the head and so can be blocked by Bella's power, as mentioned in The Twilight Saga: The Official Illustrated Guide.

History
Heidi's gift drew the Volturi's attention in the late 1500th century. Aro found her skill valuable enough to acquire her.

New Moon
Near the end of New Moon, Heidi is seen leading a group of tourists into the Volturi's head chambers for the members to feast on. In the movie, she tells the tourists to stay together before heading into the chamber.
