Chibi Ghidorah is a three-headed dragon kaiju originating from the Chibi Godzilla children's media franchise. Its name combines "chibi," meaning small or little in Japanese, with "Ghidorah," reflecting a diminutive and cute adaptation of the classic King Ghidorah design. The character debuted in the 2018 picture book *Do Your Best, Chibi Godzilla*, later appearing in the web series *I'm Home! Chibi Godzilla* and the television anime *Chibi Godzilla Raids Again*.
Physically, Chibi Ghidorah is a bipedal, golden-yellow dragon with two wings, two tails, and three heads each adorned with white horns. The heads display distinct facial expressions: the middle head shows an open-eyed, cheerful look; the right head (from viewer perspective) appears relaxed with closed eyes and mouth; and the left head consistently wears a mean or aggressive expression. This visual trio mirrors the character's core trait of housing three separate personalities within one body.
These three heads embody conflicting personalities, leading to frequent internal bickering. The consistently friendly and sociable middle head often assigns affectionate nicknames, such as "Mego-yan" for Chibi Mechagodzilla. The aggressive right head readily threatens violence, including deploying gravity beams. The left head presents a superficially agreeable demeanor while harboring opportunistic motives, openly acknowledging the potential to monetize friendships. These clashes drive comedic interactions, particularly during decision-making or resource allocation like arguments over food expenses or mushroom distribution.
Chibi Ghidorah's history spans multiple stories. In *Do Your Best, Chibi Godzilla*, it participates in lighthearted activities like outrunning Chibi Godzilla in a footrace, reacting with delight to Chibi Godzilla's fiery tears. During a Christmas-themed episode of *I'm Home! Chibi Godzilla*, the heads' inability to agree on gift advice for Chibi Godzilla causes frustration. The anime *Chibi Godzilla Raids Again* features specific arcs: when Chibi Mechagodzilla arrives on Monster Island, the heads offer conflicting responses to his friendship request and later quarrel over discovered matsutake mushrooms, though the middle head insists on sharing one with the newcomer.
Later episodes show Chibi Ghidorah joining group activities like Chibi Godzilla's "Monster Study Session," where the heads provide incorrect trivia answers, and participating in destructive antics such as demolishing Chibi Mechagodzilla's model city—an act met with initial hesitation but eventual compliance. The character also appears in scenarios involving Chibi Godzilla's physical transformations, beach cleanups with Chibi Hedorah, and comedic misunderstandings interpreting Chibi Godzilla's destructive urges as puberty. Notably, Chibi Ghidorah serves as a supportive figure when comforting Chibi Mechagodzilla over Chibi Godzilla's temporary departure.
The character possesses abilities including flight via wings and gravity beams—energy-based attacks mentioned as threats but rarely demonstrated. Durability is evidenced by surviving self-inflicted bites and external assaults like Chibi Mechagodzilla's eye beams. A signature non-combat ability is singing, performed with each head contributing a distinct pitch, often acting as a unifying activity amid internal conflicts.
