Not very much is known about Elise's past, but it is thought that her childhood wasn't too happy. It has been seen that she has had bad experiences in New Mexico when she was a young child, and mentioned that she has lived in Japan when she was a teenager. Though, in Japan, she did have a bad run in with the Koshugi clan when she lived there, so she does have a blood feud with the clan.
Elise is an athletic-built woman with purplish eyes and maroon hair, wearing a white short-sleeve shirt, jeans and maroon shoes.
Elise loves her husband Chris and doesn't always approve of him hanging out with Dan or helping him with his revenge plots, but never tries to stop him. While she usually doesn't get along with Dan, they seem to be a bit more friendly towards each other as she has assisted him with his schemes, though they can still be pretty hostile to one another. Elise has a brother named Ben, who, along with her parents, seems to not like Chris very much. She is an agent for the government with her code name known as the Dancing Shadow, and has kept this a secret from everyone, including her parents and even Chris. It has been hinted in one or two episodes that she wants children, but Chris is reluctant for unknown reasons. She has a strong phobia of magicians and roadrunners due to a traumatic experience in her childhood. She can be selfish at times, such as in Dan Vs. Dancing, when she went to great lengths to win a dancing contest to fulfill her childhood dream, but she is generally kind and friendly to most people. Elise is named after her mother Elise Sr., and so her mother often calls her junior, much to her chagrin. She has had multiple boyfriends in the past, and in one episode her parents even tried to set her up with one named Colby, but she remained loyal to Chris.
- She and Chris may both be fans of the popular video game called Space Invaders as they have lamps based off the game.
