Here are some old figures from the Rogue Trader era. The Space Orcs had a curious Nazi biker quality to them. Citadel’s earlier use of metal figures as opposed to plastic seemed to allow a scope to added personality that seems lost now. The newer plastic figures draw variety from interchangeable heads and arms.

Perhaps even more interesting are the Squats. There used to be a nice range of these figures, cleverly sculpted with lots of personality. However, Games Workshop decided to shelve the Squats apparently because they did not mesh with the 40K world and possibly because they gave the game the appearance of a light work-over of the original Warhammer universe now simply dressed up in spacesuits.
