This custom minifigure is still a work in progress as there needs to be a tube that would connects the flamethrower gun and the fuel pack together, however it is still a great idea for a Flame Trooper.

Using the LEGO Minifigures Series 4 Hazmat Guy, he has been painted silver and the fuel tank has been given some painted detailing.

This minifigure does have scope to be improved upon but we really like the concept!
