** (Neo) G Red's MirrorCharacter, G Black, was an event-only borg distributed exclusively at the 2004 Jump Festa hosted by V-Jump magazine and through Capcom back when they were attending the Makuhari Messe convention center, and the only way to obtain it nowadays is through a hack or a bug.
** Hacking the game also allows one to access the [[FinalBoss Galactic Emperor]] as a playable borg, as well as the combined borgs as a single unit. However, the latter borgs are barely playable and tend to freeze up during gameplay.
%%* UrbanLegendOfZelda: There are persistent rumors as to how to legitimately unlock G Black as a hidden secret character in the international release, without resorting to hacking or glitches.
* WhatCouldHaveBeen: Mana's [[http://www.capcom.co.jp/gotchaforce/warehouse/images/wh0027.jpg older]] [[http://www.capcom.co.jp/gotchaforce/warehouse/images/wh0037.jpg sister]], [[http://www.capcom.co.jp/gotchaforce/team/images/mina.jpg Mina]], whose role was cut from the plot. Significant in that [[spoiler:she was going to be the primary antagonist; the position was instead filled by Orochi]].
