Inspired by another custom that used Han Solo as the base so I decided to try to take a stab at it. Very disappointed there isn't an official 6 inch Marty Figure. Funko made a Rocketeer figure but not Marty or Doc?!

Used Black Series figures for my custom. Lukes head was the closest I could think of that was affordable.
A better one would be the marvel select unmasked Amazing Spider-man figure from the 2012 movie but I was worried it would be too large and/or not fit. Also, the figure is in the $45+ range, so not even worth the try.

Body/Jacket: Han Solo
Head: Luke Skywalker
Red Jacket: Finn's jacket
Hoverboard: From an eBay hoverboard fridge magnet

Also added a magnet on his foot so he can post with the hoverboard.
