Alvin Seville is the first born by five minutes of the three chipmunks. He is impulsive, charming, musical, and full of energy. He makes up hard-brained schemes to get what he wants whether it is trying to help his brothers, or keeping Dave, his adoptive father, from figuring something out.Alvin's signature color is red and plays the harmonica, piano, and guitar. He is also the leader of the group and the lead singer. He describes himself as 'the awesomest one'. Alvin also often pushes Dave over the edge which always gets him yelled at. Despite this reason and the fact that he takes advantage of his youngest brother, Theodore, he cares deeply for them but is 'too cool' to admit it.
