I love Funko's mini-fig blind bags, especially the Walking Dead ones. The Big Bang Theory ones were cool too, but they were smaller. Game of Thrones was cool but felt hollow - so they seemed cheaper. The Walking Dead set the standard.
So when I found out the Sci-Fi ones were similar size and density and grabbed one, I had to have them all. Well, I don't have them all, but here are the ones I do have (pictured below).
Figures not shown here include Predator with green blood, Invisible Predator, Alien, Metallic Alien, ET, Spock, Mars Attacks, Mal from Firefly, Rocketeer, and Judge Dredd.
