Luke Skywalker in Battle Poncho is one of the final figures from the original Kenner Star Wars toy line. Based on the middle portion of Return of the Jedi, Luke is dressed in all black with a helmet, and removable cloth poncho.
On Endor, Luke was part of the exciting speeder chase and then eventually turns himself over to the Empire. He uses his lightsaber to deflect laser blasts from the Biker Scouts. Later Darth Vader examines the construction of the new weapon. Unfortunately this figure didn't come with a little plastic lightsaber. Luke in Battle Poncho came with the poncho, a black belt with holster, and a black blaster. (The belt pictured above comes from a Bionic Six figure)
The corresponding Leia in Battle Poncho came with a removable helmet, but Luke's is part of his sculpt. Like not including the lightsaber, it's unfortunate that the helmet is non-removable. Luke wears the same outfit minus the helmet and poncho in the final battle. I wonder if they were saving that version of Luke for a future wave.
