Celtic Demons

The Celtic Demons were an army of demon-shaped robots that were sent to kidnap The Scotsman's Wife. They made their first appearance in Episode XVII: Jack and the Scotsman, Part 2, and later appeared in Samurai Jack: Battle Through Time.

It is unknown how the past Aku's destruction affected their existence.

Appearances
The Celtic Demons were first seen in Episode XVII: Jack and the Scotsman, Part 2. They were the main enemies in that episode, where they were planning to eat The Scotsman's Wife when the moon was full until Jack and The Scotsman arrived to stop them. They were eventually destroyed by The Scotsman's Wife after their leader called her fat.

Skills and Abilities
They hunt in massive battalions and were heavily armed with deadly weapons.

Trivia

 * Their leader (the Master of the Hunt) is the only one that is a true demon rather than a machine. He is based on an ancient Celtic Pagan deity.
 * It's unknown how the demons eat and digest the Scotsman's wife's flesh since all of them minus their leader were machines.
 * They were among the toughest adversaries that Jack and the Scotsman have ever faced. Despite both of them teamed together, they were on the verge of defeat, until their leader called the Scotsman's wife fat.
