Ali Mills is the main love interest of Daniel LaRusso in The Karate Kid. During the events of the first film, she seems to take an instant liking to Daniel and the two begin to date and eventually fall in love, much to her ex-boyfriend Johnny's dismay. It is revealed later in The Karate Kid Part II that Ali left Daniel for a football player from UCLA after the senior prom.
Ali is sweet, and funny. She cares a lot for Daniel, and is very supportive of him at the tournament. She also went out with Johnny Lawarance before and Johnny started to be mean to Daniel because he still loved Ali. But she doesn't care for him anymore.
