Klarc is the Sixth KRONOS unit created by Invader Plazatrax. He is an experimental KRONOS unit.
Klarc looks like the standard KRONOS unit, but with large rectangular eyes. Klarc has a thin membrane stretched across his antennae as to pick up a much wider range of sound frequencies. His voice box can also produce a much wider range than normal Irkens or SIR units.
Klarc is very odd. He almost exclusively talks to more simple life forms. He tends to ramble when talking and changes subjects frequently, sometimes even dropping out of the conversation entirely.
