Monster X (モンスターエックス Monsutā Ekkusu), also known as Keizer Ghidorah (カイザーギドラ Kaizā Gidora), is a skeletal Ghidorah kaiju created by Toho that first appeared in the 2004 Godzilla film, Godzilla: Final Wars.
Monster X was summoned by the Xiliens from the Gorath asteroid, which has unknown origins. Keizer Ghidorah is a form of Monster X. It is unknown if the Xiliens themselves created Monster X or if he was simply discovered by them. After Gorath impacted Tokyo and destroyed the city in the process, Monster X emerged and fought Godzilla in a titanic battle until both kaiju entered a beam-lock, after which he transformed into Keizer Ghidorah and quickly turned the tables against the King of the Monsters. It was only after Godzilla received an incredible boost in power from the Gotengo that he was finally able to defeat the terrible space monster, sending the creature into low Earth orbit with his atomic breath, where he exploded.
Powers and Stats
Tier: At least 7-B with beam attacks. 6-B via meteor. | Likely 6-B
Name: Monster X (first form), Keizer Ghidorah (second form)
Gender: Unknown, presumably male.
Attack Potency: At least City level via beam attacks (Beams equaled Final Wars Godzilla's normal atomic breath, which blasted Hedorah and Ebirah high into the air and later (along with some buildings) across multiple city blocks.), Country level via Meteor | Likely Country level, possibly higher (overpowered Godzilla during a beam fight, whose atomic breath is this strong)
Speed: Subsonic by virtue of size (Final Wars Godzilla qualifies as subsonic by virtue of size), possibly Sub-Relativistic reaction (reacted to Godzilla's atomic breath, which showed sub-relativistic speed during the meteor destroying feat) | Unknown (Keizer Ghidorah does not move much), possibly same as Monster X
Lifting Strength: Class M (lifted Final Wars Godzilla, who weighs 55,000 metric tons) | Class M via gravity bolts (lifted and threw Godzilla), possibly Class M+ by virtue of size (weighs 100,000 metric tons)
Striking Strength: At least City Class (physical attacks injured Final Wars Godzilla, who was staggered but mostly unfazed by beams equaling his normal atomic breath), possibly Country Class via scaling from the blue spiral atomic breath | at least the same as his first form, likely higher
Durability: At least Small Country level via meteor (took 15 seconds to be destroyed by Godzilla's atomic breath), At least City level, likely Country level normally (withstood an explosion large enough to cover a large portion of a city, was staggered but mostly unfazed by Godzilla's atomic breath, survived Meteor's destruction) | Likely Country level (absorbed Godzilla's energy; it took several seconds for his body to be destroyed by the red spiral ray, which is presumably stronger than the blue spiral ray)
Range: Several hundred meters via gravity bolts
Standard Equipment: None
Weaknesses: None notable | Energy absorption has its limits and can hurt Keizer Ghidorah if too much energy is channeled at once; seemingly less mobile than his first form
Notable Attacks/Techniques: Keizer Ghidorah's gravity bolts can be used to lift and throw enemies; Keizer Ghidorah can also drain energy from enemies through its bites
Key: Monster X | Keizer Ghidorah
