Luke has helped Super Bunny battle many enemies but his main duty for the team is research. He wants to know what Super Bunny is, where he came from and why he is here. His studies were aided by the arrival of Super Mouse from an alternate dimension, who remembered a lot more about his past than Super Bunny does. However, results of Luke's research are still inconclusive.
Luke also designs, constructs and maintains all the gadgets and gizmos belonging to Super Bunny and his friends, including Starbird.
