He’s assembled from the spare parts and scavenged scrap metal. Originally he was just a simple machine, but over the years and after many upgrades he’s started to resemble a dog more than just a memory stick with feet.

• Hermit's strange little companion.
• He's about size (and shape) of a terrier. He also has a terrier's personality.
• Which is why Hermit calls him a scrap terrier. Fondly, of course.
• His appearance, details especially, are constantly changing, since Hermit fixes and upgrades his parts when he finds something suitable.
• He is self aware to some extent. But since he's just a little dog there isn't many thoughts in his head.
