Battra is solely concerned with the defense of the Earth, and will do whatever he can to protect it. Unlike Mothra, Battra sees humanity as a blight on the Earth that must be destroyed if the planet is to survive. Battra has made it his mission to eradicate the human race, which puts him into conflict with Mothra. However, despite his typical personality, he has occasionally shown heroic traits, as seen when he decided to help Mothra after Godzilla nearly killed her.
