Ratman is also rumored to appear in GTA III, but alleged sightings are on a much smaller scale. He is thought to be found in the underground Subway tunnel near the Liberty Campus, or in alley ways in Staunton Island. A poster of the musical Rats (a parody of the musical Cats) can also be seen in the Subway, this could be a plausible reference to the Ratman. People have noted similarities between Darkel and Ratman, even theorizing they could be the same person. However this seems highly unlikely, as Ratman does not have a gang like Darkel, and lives in Staunton Island as opposed to Portland where Darkel would’ve resided.
