Irradiated giant monsters have been a mainstay of American disasters since the 1950s. As far as the public is concerned, these creatures are quickly killed and life returns to normal. The truth, as is typical, is far stranger than fiction. In secret, the American Military has been capturing monsters for decades, keeping them "in-storage" for a more dire emergency. When threatened with a martian invasion, there was no choice but to release... Battalion 51!
If we're going to have Martian Invaders attacking '50s America, we're going to do it right!
The Creature (The Missing Link)
Captured near the Black Lagoon in the 1950s, The Creature is a strange hybrid between man and fish that has never been explained by modern science. It is stronger, faster and tougher than any human being and can swim quickly in salt or fresh water. The Creature possesses a reasonable level of intelligence and has been trained to attach mines to Communist Submersibles and chase down and devour beatniks.
The 50 Foot Woman (Susan)
When Nancy Archer was irradiated by unknown, alien, energies, she grew to a height of fifty feet and went on a rampage of revenge against her former lover. After a disturbing rampage, Nancy was captured and taken to Area 51 for study. Possessing incredible strength and an unbridled rage, "The 50 Foot Woman" is a dangerous foe for any enemy.
The Blob (B.O.B.)
An alien creature so fearsome that it cannot be stopped by conventional means, what madman would use such a thing as a weapon? Well, the military has experimented with with freezing the Blob, shattering "chunks" off and loading them into munitions. The deaths from these experiments are mounting, but some success has been gained. In the face of total alien invasion, the Blob may be the only hope for the human race.
The Fly (Dr Cockroach)
Professor Brundle's experiments ended in tragedy, but his work lived on. The brightest minds "rescued" from Nazi Germany quickly perfected the "Brundlefly" process, combining superhuman agility and senses with the most supreme intellects that could be found. At least, that was the plan. Unfortunately the Brundlefly process is degenerative and the volunteers only survive a few weeks, and the cost is so prohibitive that only one can be created at any time. Still, with an agile super-genius leading them, Battalion 51 are even more fearsome.
Created by ill-advised and unsupervised experiments in "gigantism", this 100-foot-tall arachnid is the ultimate weapon in the Battalion 51 arsenal. It is, frankly, surprising how few problems cannot be solved by sending a giant spider to attack something. Alien invasion? Giant Tarantula. Cuban Missile Crisis? Get a giant Tarantula to eat Castro. Debt crisis because some idiot though trickle-down economics was a real thing and deregulated the banks? Feed the Republican party to a giant Tarantula.
Were I to undertake this team as a project (and I am tempted), I'd probably look at 15mm for my scale. All Quiet On the Martian Front miniatures and a couple of fantasy and horror monster minis for the "heroes". It would make one hell of a fun con-game and could easily be done with some clever tweaks of SS4. Oh well, off to the internet to browse minis again...
