Planet: name unspecified. This spacefaring humanoid species desired to be isolated in 2366 at first contact with the UFP, as some of its natives were undergoing metamorphosis into noncorporeal creatures. Within four years, at least some natives were involved with the Maquis on Volan III. Among their technology, Zalkonians have developed a projectable paralysis field that can strangle the crews of nearby vessels.
