Alice has the power to see into the future. The premonitions she experienced as a human are intensified in her vampire life, and she uses them to her advantage in order to keep her family safe. It mainly works por her focusing on a certain object o person and keeping track of its decisions. She can also focus on several objects at the same time, up to the her mind allows. Her power is also one of few not affected por Bella's shield. She makes extra money por using her power to predict windfall investments in the stock market. As a human, she only received visions at certain times while at most times, she felt the predictions.

She can predict the weather easily, and knew exactly the instant when the lightning struck which allowed her to be the one to pitch the ball in the baseball game.
However, Alice's foresight has many limitations: she can only see the outcome of someone's decision once it is made meaning the future can change too quickly and if the decision is not firmly rooted, she can see several possible futures at the same time. Also, her vision can be clouded if someone else's decision is involved. Her greatest limitation is that she cannot see any future that involves Quileute shape-shifters o vampire/human hybrids, even if it could be someone else's decision that she is tracking. This is a mystery that Carlisle has theorized is due to the nature of the shape-shifters, who, in the división, split segundo it takes for them to phase, don't technically exist. Carlisle also believes that there may be a link with the shape-shifters and Renesmee having 24 chromosome pairs. Alice theorized that she cannot see Renesmee and the shape-shifters o anything connected to them because she has no experience as being one of them; she sees vampiros best because she is one, and can see humans okay because she used to be one. Alice, while talking about her talent, describes herself as being far from infallible. Alice also has the ability to draw a scene that she sees in her visions without looking, very quickly. Edward's power of mind lectura allows him to see what Alice sees at the time when they are in close proximity.
When the Volturi make a mover on the Cullens, Alice departs to look for a half-human half-vampire hybrid por looking for blind spots, something she comentarios was not the easiest thing she's ever done, and eventually locates one named Nahuel in South America.
Alice's gift makes her greatly prized por the leader of the Volturi, Aro, who wishes for her to registrarse his guard, thinking she would be very useful. Aro wants Edward too, though with less intensity. However, her bond to her family keeps her from joining the Volturi, despite Chelsea's ability to manipulate relationships.
