Each character has different attributes. Han Solo and Leia can also be used to replace Luke in gameplay, but unlike Luke who has numerous lives, Han and Leia only have one life each. Obi-Wan Kenobi can resurrect Han Solo or Princess Leia five times (in the Game Gear and Master System versions, the player is even required to kill and resurrect them in order to earn the last 10% completion points and see the ending), R2-D2 can display a map of the Death Star hallways, and C-3PO can provide information on the current part of the game. Darth Vader makes his only appearance on the Game Over screen.
