What Are Guilty Gear's Heavy Metal References?
Guilty Gear is a fighting game that doubles as a record collection. Its creator, Daisuke Ishiwatari, is a documented Queen devotee who grew up on Western rock and metal, and he filled his game's names with tributes. This page lists the documented ones, not every rumored one. Every entry below comes from a source opened during this page's research.
The evidence comes in two kinds, and the page keeps them labeled. The first kind is creator level: names that reference works on Ishiwatari tie to the bands directly. The second is the catalogue: the move and character names collected by the Music References FAQ for Guilty Gear XX, a fan compiled list first published in 2003, which this page uses for move names and the plainer character names.

A borrowed habit, openly borrowedThe references are not Easter eggs sprinkled on a finished game. They are a working method Ishiwatari took from his stated chief inspiration. Bastard!!, the manga he named as the thing that inspired him, is documented as naming its characters, locations and key objects after rock and heavy metal musicians, and reference works on Ishiwatari state plainly that he borrowed that trait into Guilty Gear. The soundtrack followed the same logic: the original game's music, composed by Ishiwatari with Takahiro Uematsu, Hatsuaki Takami and Takuya Moritou, is rock and heavy metal, and its themes became one of the aspects the series is most known for.
A last honesty note. Guilty Gear reference lists online run far longer than this page, and some entries rest on nothing firmer than a name sounding similar. This page prints only what could be verified from an opened source during its research: the names tied to Ishiwatari in reference works, and the move and character names catalogued by the Music References FAQ, a fan compiled document first published in 2003 that sticks to listing terms and their musical roots. Rumored references that no opened source documented are left out, on purpose.
