Military conquest may work well for the Borg, but other extraterrestrial ne'er-do-wells favor a more deceptive path to victory. Yes, some aliens favor the long con.
Just consider "The Claws of Axos," a classic "Doctor Who" adventure and nasty confidence trick that plays out as follows:
- Disguise your true hideous form and appear as golden humanoids in form-revealing leotards. Talk British.
- Crash your organic spacecraft on Earth and claim to be out of gas.
- Inform the earthlings that you're short on cash but will barter for fuel.
- In exchange for a fresh tank of petrol, offer the humans a miracle substance called Axonite, a thinking molecule that can replicate any substance -- such as gold, helium-3 or Thai Red Bull.
- Drain the energy of all life forms on Earth.
See, the Axons are not a species of individuals. The ship, its crew and the precious Axonite itself are all part of a single parasitic organism -- which should have been expected since the Axon ship looks like a leech of some sort.
In the 1971 "Doctor Who" adventure, the titular time lord naturally thwarts the ravenous aliens, but it serves as a great reminder: Whether you're dealing with Zerg, Tyranids or just a good old invasion of Bugs, never trust a ship that poops.
