!Tropes
* InspirationForTheWork: Author Jin Haganeya has [[https://www.youtube.com/watch?v=9Ff8VZrAhyg stated]] that the name Demonbane came from him playing ''VideoGame/SuperRobotWars4'' as a child and naming the "Grungust" SuperRobot upon unlocking it "Demonbane".
* ScheduleSlip: The English release, so much so that among English-speaking VisualNovel readers, it had the same reputation as ''VideoGame/DukeNukemForever''.
* WhatCouldHaveBeen: Haganeya has talked about a proposal for "Project D2" or ''Zanma Taisen Demonbane'', a {{Sequel}} to ''Kishin Hishou Demonbane'' which follows Kuzaku and Another Blood as they travel across different dimensions and outcomes, but this hasn't turned into a proper story minus story snippets. [[spoiler:However, the climax of the story where Demonbane the Vortex Blaster destroys Azathoth is the foundation of Haganeya's {{Manga}}, ''D.Y.N. Freaks'']].

!Miscellaneous
* This series made its ''VideoGame/SuperRobotWars'' debut in ''VideoGame/SuperRobotWarsUX''. However, the game doesn't adapt the original ''Zanma Taisei'' visual novel, but rather the ''Kishin Houkou'' AnimatedAdaptation instead, making this the first series inclusion in ''Super Robot Wars'' that's based off of a visual novel.
* According to Creator/HikaruMidorikawa, Master Therion served as the inspiration for Asakim Dowen, the recurring antagonist of the ''VideoGame/SuperRobotWarsZ'' saga (both were voiced by him). That the latter was also sealed on Mars by the time the ''Second Super Robot Wars Z'' occurred only strengthens the similarities.
