Made an appearance in Super Robot Wars - the original series, The Last Red Shoulder, Red Shoulder Document: Roots of Ambition, and Pailsen Files are all set to debut in Super Robot Wars Z2.
A BGM named "The Advance of Warhorses" popped up at the beginning of Scenario 29 of Super Robot Wars Z2: Saisei-Hen, which makes Chirico go nuts. This song is remade from the original Red Shoulder March of Armored Trooper VOTOMS since Banpresto couldn't purchase the song's licensing, but this version is very well-conceived.
The Other Darrin: Yuri Nashiwa voiced the Phantom Lady/Fyana in her first speaking appearance in episode 3, but was quickly replaced with Kazuko Yanaga. Albert Killy was initially voiced by Kenichi Ogata in the first episode, but was voiced by Saburo Kamei in all appearances afterwards.
