In The Mighty Ducks he is the star player for the Hawks. Coach Gordon Bombay discovers that Adam actually resides in the Ducks' district boundaries and threatens Reilly into transferring Banks to the Ducks. Ducksworth makes a deal with Reilly about the Hawks keeping Banks, however Bombay refuses since it would be against fair-play.
In D2, he is concerned about playing well and enough in each of the games because scouts are watching all of the matches. Later, Adam injures his wrist in the first match up against Iceland. He attempts to hide it from his teammates and Coach Bombay, the latter eventually finds out and benches him to prevent any further injury.
In D3, Adam's skill allows him to join the varsity team at Eden Hall Academy, much to his displeasure. Fortunately, Adam returns to his teammates' side at the JV-Varsity Showdown. Throughout the trilogy, Adam has been the one to sustain the most injuries out of the entire team. Over the course of all three films, his personality ranges from being a quiet follower in the footsteps of the tougher Hawks to a devoted member of the Ducks. He still shows moments of being guillible and unable to speak up for himself but he overcomes those moments in every film.
