Along with the release of the 3-episode OVA, Super Robot Wars Original Generation: The Animation, Banpresto also produced a three-volume series of audio drama CDs entitled Super Robot Wars Original Generation: The Sound Cinema. Besides short omake segments, the Sound Cinemas introduced a new sub-plot to the anime. Featured within this side-story were mecha, such as the Astelion AX and the Mironga, which are included in Super Robot Wars Original Generations.
