Vigor Junkies

According to The Art of BioShock Infinite, Vigor Junkies were planned to be one of the types of enemies. As Columbia's version of the Splicers from Rapture, they suffer psychological deterioration as result of excessive Vigor abuse. However, the Rapture comparison limited the use of Vigor Junkies in the game, and an in-game explanation by Citizens' dialogue in the Columbia's Fair mentions that average Citizens were not that interested in obtaining Vigor abilities, due to the formula "kinks" that Fink needed to work out. Small aspects of the Vigor Junkies are still present in two of the characters, the Crow and Cornelius Slate. Both characters' madness has been exacerbated by their repeated use of a particular Vigor, Murder of Crows, and Shock Jockey, respectively, and the latter even has large Shock Jockey crystals protruding out of his head. Although Fireman's appearance did not appear in the Vigor Junkie concepts, a Vigor Junkie character in a top hat, glasses, and a black coat shows many of the same Devil's Kiss abilities as a Fireman.
