Alec is mostly described to be the nice twin but he's actually not. He works quietly and keeps to himself, studying every attack of the enemy, analyzing on when to give out his attack. Among the family and the guards, he is the least apathetic of them all. He's kind of animated in some way, as the books says, he was the one who teased Jane and Edward in New Moon. I noticed also that he was smiling most of the time in Chapter 21, Verdict. Alec has very dark brown hair, lips less full as his sister's and the same red eyes like the rest of human blood-drinking vampires. He looks gorgeous indeed and will make every girl drop dead at the sight of him. Alec has the common abilities a vampire has, speed, strength, und so weiter. His gift though, is extremely powerful. While her sister induces pain and can only concentrate on one person, his gift is the exact opposite, the antidote. His special ability is to cut off one's senses and he can also do this to a multiple number of people. This power is in the form a misty gray haze.
In the book it was said that Alec and Jane looked like 13 year olds, but in the movie, they were portrayed by Cameron Bright, then 16, and Dakota Fanning, 15...
