Ko’dor are an octopus like species that arise from the swamps of the planet Luvwa. They have the ability to transform their bodies into any form or shape they want.
When a Ko’dor wants to infiltrate an animals social structure (say, humans) they “single out” an individual to transform into. They listen to and mimic their voices, study their bodies, and finally, shapeshifter into their form.
To get rid of the individual they “singled out” they use their ink, a chloroform like substance, to knock them out, and than they hide the body.
It would likely by easier to kill they individual, so my question is, what is a plausible reason why the Ko’dor would knock out their victims, instead of killing them?
-The Ko’dor’s Ink knocks out victims for a week. They hide the body, and feed it, expell its waste, all that stuff
