Science fiction is a common theme for films and so is natural that some companies made figures inspired by those. The more common figures are, probably, from Star Wars films.
Britains
Britains produced some figures inspired by Science fiction. There were 6 different figures that were made in yellow plastic (for the good people) and in black plastic (for the evil). They have metal bases like Deetail figures. These figures were introduced in 1981 and were deleted in 1987.
The figure in the middle is a woman. There are two types of “pistols”.
The last pose seems very uncomfortable. There are two different “rifles”.
Evil soldiers have the some bodies but different heads. Bases are in bronze colour.
Monsters were made using normal bodies with heads and appendixes in a rubber material.
