Tradewest produced Battletoads & Double Dragon
with Rare without Technos Japan's supervision to use the Double Dragon
characters in the game. As a result, even though the Battletoads
characters were faithful to themselves (considering Rare developed this game), many of the so-called Double Dragon
characters are either, misnamed or misrepresented in the game.
- A machine-gun wielding boss that resembles Willy, the main bad guy from the original Double Dragon, is named "Roper" in the game, who was a small fry enemy in the series.
- A small fry enemy in Stage 5, a fighter who wears a bandanna and throws shuriken, bears a vague resemblance to Williams in Double Dragon II, but his name is "Lopar", which was Roper's name after it was romanized in the instruction manual for the first NES game.
- A few other enemies, like the "shadow marine", "doorman of doom" and the "windowman of doom" are described in the manual as Double Dragon enemies, but in reality they never appeared in an actual installment of the series.
- The whipwoman Linda makes an appearance in the third stage, but in the manual she is given the fullname of "Linda Lash". The Lash surname has never been used in a Double Dragon and has only appeared again in the bombed live-action Double Dragon film.
- And finally, a character by the name of the "Shadow Boss" is described to be the Double Dragons' main nemesis. However, no such character was ever featured in any of the Double Dragon games. The "shadow boss" name was actually Jimmy Lee's mistranslated title in the first NES game, wherein Jimmy was the final boss in the game (a plot twist that wasn't in the original Arcade version and was ignored in subsequent versions and installments Technos made). The "Shadow Boss" in BT/DD bears a vague resemblance to Burnov, the first stage boss from Double Dragon II.
