Critter is a minor antagonist from the War of the Underworld storyline within the larger Alicization Arc. He works as a hacker consultant in the cyber operations department at Glowgen Defense Systems, though he's also a first-class cyber criminal operating on the side—basically the kind of guy who knows how to break into systems and isn't shy about doing it for the right price.
