Godzilla Kaiju Daikessen ("Godzilla: Monster War") is a 2D fighter for the Super Famicom featuring famous Toho kaiju. While the game was released in Japan only, a US version was in production at one point under the working title Godzilla: Destroy All Monsters. It is the sequel to the 1993 TurboGrafx-CD Godzilla fighter Godzilla: Battle Legends, also developed by Alfa System.
There would not be another Godzilla tournament fighter similar to this game until Godzilla: Destroy All Monsters Melee, which came out for the Xbox and GameCube platforms.
The game features the following kaiju as playable characters:
- Godzilla: The eponymous big green lizard and the most famous kaiju.
- Anguirus: A yellow ankylosaurus who is often Godzilla's ally.
- King Ghidorah: A three-headed atomic dragon from space. One of Godzilla's strongest rivals.
- Gigan: A cycloptic creature with hooks for hands and an enormous buzzsaw in its torso.
- Megalon: A beetle-like kaiju with saw arms.
- MechaGodzilla (Showa): Godzilla's metallic twin. This is the slightly weaker Showa Era version (pre-1989).
- Biollante: A colossal (even for kaiju) plant-like genetically-modified monster who attacks with its whip-like tendrils.
- Mothra: A gigantic moth who often fights for the sake of humanity. Her special attack includes her rival moth kaiju Battra in a brief cameo.
- MechaGodzilla (Heisei): The Heisei Era version (post-1989) was introduced in the 1993 movie Godzilla vs. MechaGodzilla 2. Slightly more powerful than its older incarnation.
- Super MechaGodzilla: An upgraded version of the Heisei Era MechaGodzilla. After combining with the anti-kaiju airship Garuda, MechaGodzilla becomes one of the most physically powerful kaiju in the universe. It is a boss character and must be unlocked for multiplayer with a cheat code. It'll also become playable if Expert mode is played.
- Gotengo: A man-made supertank that is capable of flying, going underwater and drilling underground to ensure it can reach any destination. Originally appeared in the 1963 Toho sci-fi adventure movie Atragon, which had no relation to Godzilla and the other kaiju. It is a secret cameo character and must be unlocked for multiplayer with a cheat code. It'll also become playable if Expert mode is defeated without using a continue.
