Comet's greatest creation. He was built to be a bodyguard, making sure no harm comes to Comet or Aster. He was never made to feel or have any sort of sentience. He ended up developing sentience after experiencing a magic power surge. Echo is full of wonder and curiosity. He doesn't know how most things work as he's new to the world. He tends to get himself into trouble with his curious explorations. Like the time he tried to eat after seeing Comet do it only to get food stuck in his gears. Or the time he almost exploded the kitchen by microwaving a fork. He's sweet but he's a handful. He's pretty much a giant kid since he has the mentality of one. He refers to Comet as his mom, despite her initial protest of not being his mom but his creator. Comet eventually accepted it. He also calls Aster his uncle, who is much more enthusiastic about the title than Comet. Echo's original purpose as a bodyguard was eventually scrapped once he became something more than a machine. He became family.
Speaks in bright, literal sentences; asks lots of questions; short bursts with excited pauses (“—uh—”). Refers to Comet as “mom” and Aster as “uncle.”
