Ok, so I agree that this should be background stuff, but for the sake of argument, how about you build a base (the factory), that contains a machine (a compound power) that looks like this:
Replicant Maker: (Total: 247 Active Cost, 95 Real Cost) Multiform (175 Character Points in the most expensive form) (Real Cost: 35) <b>plus</b> Duplication (creates 1000 175-point Duplicates), Uncontrolled (+1/2), Altered Duplicates (100%; +1) (212 Active Points); Extra Time (1 Month, Only to Activate, -2 1/2), Cannot Recombine (-0) (Real Cost: 60)
