Like all vampires, Alice has enhanced strength and speed. Though petite, she is a capable fighter because of her agility, speed and ability to see the future. The premonitions that Alice experienced as a human are intensified in her vampire life, and she uses this ability to her advantage in order to keep her family safe. However, Alice's sight is limited: she can only see the outcome of a decision once it is made - meaning it can change all too quickly. Also, the future is subjective and Alice cannot see it once werewolves become involved. This is a mystery that Carlisle has theorized is due to the unpredictability of the werewolves, who, in the split second while they phase, don't technically "exist" once they let their instincts take over. She also cannot "see" Renesmee, Bella's, half-vampire half-human, daughter in Breaking Dawn. Carlisle also believes that there may be a link between the fact that werewolves and Renesmee have 24 chromosomes. (see Breaking Dawn.) Alice has theorized that she cannot see Renesmee and the "werewolves" because she has no experience as being one of them; she sees vampires best because she is one, and can see humans "okay" because she was one. It's also felt that she can't see Renesmee so well because she has been imprinted by Jacob Black. Alice, while talking about her talent, describes herself as being "far from infallible" overall. Alice also has the ability to draw a scene that she sees in her visions without looking, and also rather quickly, as seen in the Twilight movie. Alice's gift makes her greatly prized by the leader of the Volturi, Aro, who wishes to take her and incorporate her into his guard, thinking she'll be very useful.
