A line-up of the available mecha from one of the versions of Super Robot Taisen/Wars, a video game series that's been around since at least the early 1990s. In theory a smart US movie studio could license a SHOGUN WARRIORS project as an official SRW adaptation and so market it in Japan.
Most of the animated SHOGUN WARRIORS are included in the above picture, plus some newer mecha from post-toyline shows and a couple new robots created just for the game--but not Danguard Ace.
Identities:
* Guy in back: Daitarn-3.
* Front Four: Mazinger Z, Great Mazinger, Grandizer, Dancougar.

* Third Row: Dragun (which can transform into Arrow or Poseidon), Raydeen, another of the SRW original mecha, Goshogun (a.k.a. Macron 1's Macstar).
* Final Four: Tryder, Combatra, Voltes V, Zambot.
