Yep, it's Gaara of the Desert! ^_^
Gaara, like Naruto, is a jinchuriki, or the (unwilling) host of a biju (tailed demon).
Thanks goes to deliquate for the idea of Xander gaining Gaara's powers 'cause that would be soo cool! ^_^
Gaara is from the anime series called 'Naruto'. If you haven't seen or heard of it, you should look it up - you wont regret it!!
ALSO: I don't own any of these beautiful pictures!!! ;-;
