Localized version

  • in River City Ransom: Underground Randy only appears in the game's prologue, a flashback sequence in which the player plays through the final level of the original (starting with the fight against Ivan until facing Slick. Strangely, even though they were Cindy's original kidnappers, they do not appear in the present portion of the game.


  • Ryūichi has a height 176 cm (5'9").
  • Ryūichi is loosely based on Billy Lee, one of the main protagonists of the Double Dragon series of beat 'em up games, which in turn was directly derived from the Kunio-kun series. The iconic "Double Dragon" theme even plays whenever he and his twin brother, Ryūji, appear.
