I was exposed to a lot of vintage horror and science fiction media as
a kid. I grew up renting the Universal Monster movies and getting out
books from the library about the history of science fiction - books that
were themselves written in the 1970s, and were thus "old" by the time I
was reading them in the early 90s as a precocious eight year old. At
the time, I had no concept that H.G. Wells, Jules Verne, the Outer
Limits (especially the episode "The Demon with the Glass Hand" - for
some reason that was the episode cited in every book that referenced the
Outer Limits), etc., were "old" and not new, current things. One of
the many things I was thus exposed to as a kid were the old Republic
Serials. These were precursors to modern TV shows, in that they were
broken down into short episodes that would be shown for a week at a time
at movie theaters, each one beginning with a recap of the last week's
episode, and usually ending on a cliff-hanger with the hero about to
(apparently) die a horrible death to ensure a return audience next week.

Republic's
sci-fi serials often featured, in at least one episode, some sort of
big, clunky tin-can robot, which has become known as the "Republic
Robot." They first appeared as Atlantean "Volkites" in 1936's THE
UNDERSEA KINGDOM, and later turned up robbing banks for THE MYSTERIOUS
DR. SATAN and in 1952, one of them was still kicking around long enough
to serve as an axe-wielding (!) "iron executioner" for the ZOMBIES OF
THE STRATOSPHERE. The Republic Robot would later be lovingly parodied
on Star Trek: Voyager as "Satan's Robot" in the "Captain Proton" holodeck adventures of Tom Paris.

While
surfing through the Brigade Games website, I spotted these little
tin-cans labeled as "Robot Mk II"s in one of their pulp lines. They're a
clear homage to the simpler, water-heater-with-dryer-hose-arms robots
of yesteryear, and I picked up a two-pack (they also offer five- and
ten-packs for aspiring megalomaniacs) for my Nostalgia entry - not just
because they hearken to an earlier era of science ficgtion, but because
they remind me of the science fiction of my childhood.
The
bases are a secondary homage; ZOMBIES OF THE STRATOSPHERE is a sequel
to RADAR MEN OF THE MOON, so I decided to paint the bases as lunar
terrain.
