It is revealed that Mothra and Godzilla are in a symbiotic relationship, which is where two species of animals take care of each other and receive a benefit from the relationship.
A lineage of benevolent lepidopteran Titans, Mothra defended the natural world in the ancient past and was revered as a goddess by ancient human civilizations, including the Iwi. Mothra possessed a symbiotic relationship with Godzilla, and aided him in battle against the extraterrestrial King Ghidorah long ago.
Godzilla is shown to have a crush on Gojirin, and she seems to return his feelings. Occasionally, Gojirin is a source of conflict among Godzilla and his friends, as both Baragon and Anguirus compete with Godzilla to impress her.
Mothra dated King Ghidorah, much to Rodan's jealousy. Despite their species are mortal enemies, the two remained together. However, Ghidorah was revealed to be cheating on Mothra by being with Hedorah every Thursday (he covered this up by saying that he was playing poker with his friends).
Anguirus was reintroduced in Destroy All Monsters as an ally and best friend of Godzilla living with him on Monsterland, a role that Anguirus maintained throughout Godzilla vs. Gigan, Godzilla vs. Megalon, and Godzilla vs. Mechagodzilla.
Personality. Despite having wrought destruction worthy of any Toho kaiju, Mothra is almost always portrayed as a kind and benevolent creature, causing destruction only when acting as protector to her worshipers on Infant Island or to her egg, or as collateral damage while protecting Earth from a greater threat.
The Bride is sent to protect Japan, after it is discovered that a group of giant monsters are leaving the Hollow Earth. She defeats the Giant Chameleon, the Giant Archaeopteryx, and Anguirus in turn, and fights Godzilla, who falls in love with her.
Godzilla attacks Japan, forcing humanity to beseech an embittered Mothra to intervene. Mothra willingly sacrificed herself whilst fighting Godzilla, but the latter is defeated when two larvae emerge from the egg and encase Godzilla in a cocoon.
Loyalty and Devotion: Mothra has shown a strong loyalty to Godzilla in the MonsterVerse. In the film "Godzilla: King of the Monsters," Mothra defies King Ghidorah, who has usurped Godzilla's position as the alpha, and remains loyal to Godzilla [1].
While at first, it appears that Mothra is simply shielding an injured Godzilla from Ghidorah's devastating gravity beams, she's actually sacrificing herself to give Godzilla the power necessary to defeat Ghidorah.
If Mothra didn't sacrifice herself in KOTM then one Godzilla definitely would've been killed including the whole planet by King Ghidorah and two Godzilla wouldn't of became his burning form in order to kill King Ghidorah to save the planet.
Godzilla was seemingly defeated by King Ghidorah, but Mothra sacrificed herself to bring him back to life. It was a poignant moment and gave Godzilla the advantage he needed to defeat Ghidorah. The film was followed up by Godzilla vs.
In the Legendary Godzilla films, Godzilla is referred to as a male. Godzilla's allegiance and motivations have changed from film to film to suit the needs of the story. Although Godzilla does not like humans, it will fight alongside humanity against common threats.
Biollante is a genetically-modified rose Kaiju hybrid created from Godzilla's DNA by the Devonians, making her Godzilla and SpaceGodzilla's half-sister. She fought against Godzilla on the Monster Islands, but was defeated and escaped into the planet's atmosphere.
Overall, while there are instances where characters and interpretations have hinted at a romantic connection between Godzilla and Mothra, their relationship is primarily portrayed as an ancient alliance and a symbiotic partnership.
Komodithrax is a giant reptilian monster who appears in episode 6 of the second season of Godzilla: The Series, "End of the Line." She is Godzilla's mate.
Ghidorah is Godzilla's greatest foe, and it isn't close. This alien creature sports three deadly serpent-like heads, it can fly, and it's capable of withstanding everything Godzilla can throw at it. Though Godzilla manages to win in the end, it's usually by the closest of margins.
