Alvin is a roller coaster. His enthusiasm is boundless and his despair bottomless. The term look before you leap definitely doesn't apply to Alvin, who is impulsive, charming, musical and full of animal magnetism. The character, who is heavily based on former member James Sawyer always seems to make up hare-brained schemes to get what his goal at the time is, whether it be trying to help his brothers, getting a date with Brittany, keeping Dave from figuring something out, or getting out of a sticky situation. However, 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). In the 2007 film Alvin and the Chipmunks and the 2009 sequel, Alvin and the Chipmunks: The Squeakquel, he is voiced by Justin Long. On July 30, 2002, Alvin was #44 on TV Guide's list of top 50 best cartoon characters of all time.
