Alvin and the Chipmunks is an animated music group created by Ross Bagdasarian, Sr. in 1958. The group consists of three singing animated chipmunks:
Alvin Seville voiced by Justin Long
ALVIN - The mischievous troublemaker, who quickly became the star of the group. He is impulsive, charming, musical and full of animal magnetism.
Alvin seems to refer to his often illogical or crazy plans as "challenging the ordinary". Alvin's signature color is red, and he has blue eyes (although in the 2007 film Alvin and the Chipmunks, he has amber eyes). He is the leader of the Chipmunks and is voiced by Justin Long.
Simon Seville voiced by Matthew Gray Gubler
SIMON - The tall, bespectacled intellectual chipmunk. Simon possesses a very dry sense of humor as well as a keen wit. Yet it is said he has an an IQ just north of Einstein.
Alvin exploits Simon's master mind for his crazy schemes because he is smart enough to carry them out. In the end, Simon loves Alvin, although he secretly worries that they share the same gene pool. Alvin also plays the bass, bass clarinet, saxophone, bagpipes, tuba, and drums, among others.
His signature color is blue, and he has blue eyes and black glasses. He is the smartest of the Chipmunks and is voiced by Matthew Gray Gubler.
Theodore Seville voiced by Jesse McCartney
THEODORE - The chubby, impressionable sweetheart. He is the youngest of the three Alvin and the Chipmunks band members. He is shy, loving, sensitive, gullible, trusting, naive and cute.
His signature color is green, which is also the color of his eyes. Alvin gets him to take part in his schemes by bribing him with food often. Because of his love of food, Theodore is also the chubbiest of the three Chipmunks and is voiced by
Jesse McCartney.
