It's rumored that some of the city's technology itself has been refashioned into a sentient form to suit Gladys' needs. These animate "tin cans", as they're referred to, form a last line of defense against citywide infiltration.
Gladys' new empire is a city built on water, so it pays to have aquatic transportation. That's where the Swamp Rats come in. They're Bloodshredders with training as frogmen -- or who eat frogs. One of those.
