Crystal Godzilla クリスタル・ゴジラ

Created by Shinichiro Kobayashi for Godzilla vs. NeoGodzilla, the original iteration of Crystal Godzilla would be the first Godzilla doppelganger to introduce the idea of a "crystal life form" fused with Godzilla's cells. A space-born monster capable of metamorphosing, Crystal Godzilla would have been a formidable foe to the earthbound Godzilla, though not many details of what the monster is capable of are known. While Crystal Godzilla would not see a big screen appearance, its crystal motif would be fused with Minoru Yoshida's monster Super Godzilla from the 1993 Super Nintendo game of the same name, resulting in the official design for SpaceGodzilla.

A year later in 1995, "Crystal Godzilla" would resurface - but in a radically different form. Acting as the third form of Ghost Godzilla in Godzilla vs. Godzilla (Story Plan A), this next iteration of Crystal Godzilla created by Kazuki Omori would literally be the 1954 Godzilla with a semi-transparent, crystalline figure, formed from the dust of one of its bones. A revived LittleGodzilla would later do battle with this new version of Crystal Godzilla. Outside of the name, it shares no similiarities with the 1994 precursor to SpaceGodzilla.

After the idea for a "Godzilla vs. Godzilla" movie was canned in favor of persuing Godzilla vs. Barubaroi, the name of Crystal Godzilla has not been seen since.

• No official concept artwork of Crystal Godzilla (2nd Version) exists. The picture in the gallery is an interpretation created by Toho Kingdom staff based on descriptions of the monster.
• Is also referred to as "Neo SpaceGodzilla" (Japanese: ネオ スペースゴジラ) in other concept art.
• Concept artwork lists Crystal Godzilla (1st Version)'s Flying Form as being 100 meters, while its Combat Form stands 120 meters.
• The "Crystal Organism" (Japanese: 結晶生物) designs featured in the gallery, also called "Crystal Life" (Japanese: 結晶生命) or "Crystal Life Form" (Japanese: クリスタル生命体), acted as alternate early attempts to fuse Godzilla with crystals before carrying this theme over to Super Godzilla for SpaceGodzilla's final design. Some concept artwork can be found in Toho SF Special Effects Movie Series VOL. 9: Godzilla vs. SpaceGodzilla (ISBN: 4924609528).
• A majority of Crystal Godzilla (1st Version) concept art can be found in the 2012 Japanese book, Heisei Godzilla Perfection (ISBN: 4048861190). Supporting text notes how the tobacco mosaic virus served as an inspiration for Crystal Godzilla's appearance, albeit replacing the virus with crystallization overtaking the monster's body, resulting in something that was "biological and not biological". SpaceGodzilla's shoulder crystals were also influenced by Crystal Godzilla's design, while Shinichiro Kobayashi is said to have been the one to propose the idea to fuse Super Godzilla's design with his "crystalline organism" concept.
• Supplementary details can be found in Koichi Kawakita's book, Heisei Godzilla Chronicle (ISBN: 4873763193).
• The mention of Crystal Godzilla (2nd Version) can be found in the 2017 publication Godzilla vs. Destoroyah Perfection (ISBN: 4798615811).
• The first version's Japanese name is written as "Kurisutaru Gojira" (クリスタル・ゴジラ), while the second version's name is written as "Kurisutarugojira" (クリスタルゴジラ), lacking the interpunct.
