Suckers

another gengie of unknown origin, suckers are parasitic organisms that stowaway on ships and subsist entirely on power, radiation, and electrical currents. They stand just under the average height of a person, and they are scrawny and mostly hairless with light, pale flesh. They have short, flat muzzles and wide, light-sensitive eyes. They have the unnerving ability to fit into almost any space, no matter what shape or size. Their skeletal structure is segmented, almost like a snake's, and they can freely disjoint and dislocate any part of their body, allowing them to elongate their limbs and squeeze through small openings. They live in the dark, stowing away on the underbellies and internal workings of ships, where they roost, using their unique biology to absorb raw ionic or radioactive power currents. On large ships with huge generators or old, outdated fission engines, the amount they take usually goes unnoticed, unless there's a whole colony stowing away. On small vessels with a light crew, they can be disastrous, and on long enough trips, they can exhaust all the power from a ship, leaving them stranded before starving to death. Suckers posess an animalistic, sub-sapient level of intelligence, and mindlessly seek out sources of sustenance and cramped, dark spaces to hide. Generally, they are treated as a minor, if somewhat off-putting, nuisance, and ships regularly check for suckers before leaving port at remote colonies and outposts.
