Luna was the second character to design after Mothra. Like Mothra, Luna's animations had already been completed on a proxy rig so we couldn't deviate too far from the original body shape. She was the more althetic, adventurous and carefree of the characters so her body allowed for a lot of expressive actions. Luna's shape was a lot more humanoid than Mothra, so we toyed around with the idea of Luna being a different species of Mothperson than Mothra, or being in a different part of the Mothperson life cycle - like being a more larvae-like creature. She saw more experimentation with her design but in the end we decided to make her resemble a more adolescent Mothperson, with remnants of her larval state still lingering, like her horns and belly armour.
