Here's one of the two most-changed figures in the Outer Space Men 2.0 lineup. Metamorpho was originally sold in a very light grey color, while the intent was to have more of a white which helps the face pop and glow and all that jazz. Also, the weapons have clear orbs at the end rather than opaque pink ones. How did they pull it off?
Simple-- the entire figure is cast in clear colorless plastic, painted white and black as appropriate. Even the head is clear plastic, with 2 of the 3 heads seeming to be more lively than the original. The red ape-like face still looks great, but the eyes seem to shine and sparkle more on the 1.0 release. There's also a weird sparkling quality on the 2.0 figure that's tough to describe, although I assume it comes from the painted clear plastic.
The white really does make it look like a different figure more in line with the coloring on a Stormtrooper or Clone Trooper from Star Wars, while the light grey looks more or less like it's own thing. Because I dig this line too much, I decided I needed both. If you don't have either release, I'd say get whichever is cheaper for you. (Unless, of course, you're buying these for kids, in which case go with 1.0. If 2.0's paint scrapes off, the exposed plastic will be clear.)
