Blüdhaven

Bludhaven was a former whaling town-turned-city, which was officially incorporated as a "Commonwealth" in 1912. The town had a generally poor socio-economic populace, owing in part to failed efforts to transform itself into a manufacturing and shipping center. Culturally and financially, Gotham City had always overshadowed Blüdhaven, possibly due to this the city had a worse crime rate than Gotham. Not unlike Gotham, organized crime syndicates always dominated Blüdhaven, which were until its final years, protected by endemic police corruption until Nightwing adopted the city as his home turf.

With the death of crime boss Blockbuster, Nightwing left the city and Batman soon sent Batgirl and Robin to pick up where Nightwing left off in protecting the city. As vengeance against Nightwing, Deathstroke had Bludhaven destroyed by a nuclear attack via Chemo. Now only an eradiated ruin, various underground bunkers hide secret government projects on creating Metahumans.
