The 1991 Sci Fi is a rather popular figure. Really, he solves for pretty much all of the criticisms of the 1986 debut figure. This later redesign features a removable helmet, smaller rifle and an overall sculpt that is less bulky than the original. In all, the figure is a strong update to a character who isn't all that high on most collectors' lists.
There's some nice content featuring the figure out there, though. For many collectors, the figure is their laser trooper. And, all the figure's gear allows for some cool posing. You'll see a bunch of these in the photos and content below.
