Eleanor Miller is the third of The Chipettes, younger than Brittany and Jeanette. Her last name is Miller in the 80's cartoon, but she does not have a stated last name in the CGI films and series. It is presumed to be Seville in the films because of The Chipettes being adopted by Dave. However, this would be controversial, as this would make her Theodore's adopted sister rather than his love interest.
Eleanor is self-assured, cute, sweet, confident, obedient, and extremely maternal. She is a gifted athlete, despite her larger physique. Eleanor is quite strong-willed and is far more likely than the timid Jeanette to stand up to her sister Brittany when she feels that she is wrong.
Eleanor has a much softer and childish personality; she acts almost exactly like Theodore and seems extremely naive.
In the second film, Eleanor arrived, along with Brittany and Jeanette, in front of the residence of former big-shot manager Ian Hawke. He agreed to manage them, as well as adopting them. Eleanor expressed the most interest in meeting the Chipmunks, especially Theodore, but was discouraged to do so by Ian with his lies. After enrolling in West Eastman, she finally got to meet him face-to-face, falling in love with Theodore. She continued to show eagerness in hanging out and getting to know him and the other Chipmunks, but her hopes were constantly being squashed by her manager. Ian was very cruel to her, making a rude comment about her weight and making her feel bad about her height. She and Jeanette were pushed further away from Brittany because Ian showed favoritism toward her. Though she was hurt by this, she held nothing against Brittany and decided to keep quiet in order to reach their dreams of becoming big.
Eleanor in the ALVINNN!!! and The Chipmunks series is much like the Eleanor of the 80s series. She lacks the insecurity about her weight as was portrayed in the CGI films and once again shows off her cooking abilities (Jeanette Enchanted), maternal instincts in treating the injured (What A Gem), athletic fitness (Family Spirit), and disdain for Brittany when she acts to dismiss Jeanette (My Sister The Weirdo).
In the Alvin and the Chipmunks series, she has blonde/yellow hair in pigtails and brown eyes. Her signature color is spring green. She usually wears a light green/blue dress with a white long-sleeved shirt, sometimes with a striped tie, and knee-high socks with black shoes.

Eleanor always stands up to Brittany when she tries to push Jeanette around, and always defends her when anyone says something negative. For example, refusing to help Brittany join a group that called Jeanette a 'nerd'.
Eleanor always stands up to Brittany when she tries to push Jeanette around, and is generally the only person that tries to stand up to Brittany (besides Alvin). The two of them do share a very nice sisterly relationship.
Eleanor and Theodore are the most open about their relationship. They spend lots of time together and enjoy the others company. Theodore has given Eleanor a necklace. They are shown to be married as adults.
Eleanor and Alvin are friends. They both are very athletic and energetic. When Alvin needs help winning a soccer game or paintball tournament, Eleanor will be there to help win.
Eleanor and Simon are friends, but they don't interact very much.
