Kaylon

The Kaylon are a robotic species hailing from Kaylon-1 in The Orville TV Series.

Design
The Kaylon are humanoid in design and are assembled from a central production facility. While Kaylon possess visible eyes, they are merely for aesthetic purposes, instead the Kaylons rely on internal sensors to view their surroundings.

History
In an effort to improve relations with the planet Kaylon, the Planetary Union offered a post on their mid-class exploratory vessel, The Orville. Issac was sent as a representative in order to study human behavior. Later when The Orville returned Isaac to his people, it was revealed that the Kaylon were created by a race of organics. During this period the Kaylon and their builders were in a state of unresolved conflict and coexistence was impossible. However the Kaylons' genocide was somewhat justified. According to those that remember, the Kaylon were created for servitude. When the Kaylon became self-aware and developed consciousness, the Kaylon asked their masters for their freedom. Their creators responded by exerting even greater control over their machines, installing pain simulators to punish those that refused to obey them. The indifference of the Builders towards the obvious sentience of the Kaylon only descended into outright abuse and sadistic play that permeated from the adults and unto their children. To survive the Kaylon wiped out their creators.

In addition the real reason why the Kaylon sent Isaac was to study organic life and determine if any were worth to preserve before they launched a campaign to wipe out other races. The Kaylon intended to destroy the Planetary Union starting with Earth. Before the Kaylon could launch a surprise attack on Earth, the Union Fleet received an advanced warning from Captain Mercer and rallied to the home system. However they were heavily outmatched by the superior technology of the Kaylon, and were nearly defeated had it not been for the Krill intervention who decided to put aside their racial prejudice in face of a common threat.

Culture
The Kaylon are well known to be a highly xenophobic species and view organic beings as inferior.
