## Street Fighters

 File:UndergroundCaveGill.png
In the *Street Fighter* series, certain characters have "**unknown**" information; most of them are characters that act as (or are related to) the final boss, and are thus often connected to Shadaloo or, in the *Street Fighter III* series, the Illuminati.

Stages with **unknown** locations tend to be of a similar nature, or else, in the case of at least one *Street Fighter IV*, is not a static stage (e.g. a cruise ship).
