Luke Skywalker's base and cardboard backdrop are designed to connect with Power F/X Darth Vader's base - so that the final duel on the Death Star can be recreated
Luke's plastic cape is removable
Once removed - it reveals the battery compartment and a button on the back of the figure
When the button is pressed - the lightsaber lights-up bright green
The saber stays lit for a few seconds and then turns off automatically
