>>51196478The video I shared explains it pretty well, but I'll repeat it here-- the film studio went against Takeshi Shudo's wishes in giving Lugia a masculine voice. He intended it to be the "maternal god of the sea". It didn't help, either, that Lugia was made genderless in the games like most other legendaries. At least his wishes sort of came into fruition in the anime episode with the baby Lugia and its mom.
