Mothra

Physical
The Monsterverse Mothra looks like a combination of the Leo iteration and her Showa iteration. She still has the white and orange fur, and her wings and eyes have a bio-luminescent blue color. Her eyes have black lining, and her claw-like mouth is horizontal, as opposed to her vertical mouth in previous iterations.

Roar
Monsterverse Mothra's roar sounds like a whistling bird, and both raises and lowers in pitch. Her moans and humming sounds as both a larva and an adult sound almost like Biollante's humming sounds.

After further research, it was discovered by some youtubers that the legendary Mothra's roars were remixed dolphin sounds.

Personality
Mothra shows great compassion and curiousness towards Humans, displayed when she lets Madison Russell touch her as a larva, and when she parts a storm to approach an unidentified human standing on an oil rig.
