Lexiconian

Lexiconians are an alien race native to the fictional planet Lexicon. They are around 3-4 feet tall and are blue in color. They, along with the ken, are the only aliens to be present in both Phase 1 and 2.

They were later reworked into the Callistonians.

Phase 1
A pair of Lexiconians experimented with various chemicals and had accidentally created a noxious gas that rendered them unconscious. Before one collapses, it opens a window in the lab. A murp then snuck inside their lab, where it began to mutate. The Lexiconians later awake, where they then begin to lament the inevitable loss of their jobs. There they are ambushed by the Murp and are killed.

Phase 2
A Lexiconian lab is infested by a predatory species of alien known as the Murps. After locking down all the doors, two surviving scientists work frantically to create a chemical agent to stop them. However, a miscalculation on the part of stress causes the two to create an unstable gas that enrages the invading Murps, allowing them to attack and kill the scientists.
