The Malkoth were a powerful species native to a region of space near the Krenim Imperium. They were known for their cities and culture.

In an alternate timeline, the Malkoth were erased from history by Annorax's weapon ship. The only element of their civilization that still existed was a bottle of Malkothian spirits, saved by Annorax aboard his ship. They were restored by the weapon ship's erasure from history.
