Lo Boyz is a gang in Gotham City.
A helicopter sent by Bruce Wayne was shot down by an RPG fired by an unknown person and crash-landed in the Lo Boyz' territory in Old Gotham. Nando led the Lo Boyz to the crash site where they ran into the Cobblepot crime family. Oswald Cobblepot managed to either kill or drive away the Lo Boyz present before the Gotham City Police Department and Tabitha Galavan showed up.
