Mothra is the most commonly appearing kaiju other than Big G himself in the Godzilla series, a beloved figure popular enough to receive several stand-alone films of her own. She was the original flying Godzilla opponent, and it’s hard to argue against the classic value of her first appearance, Godzilla vs. Mothra. She introduced the concept of a “good monster” fighting to protect the Earth from Godzilla, but would then go on to team up with him many times to take down greater threats. The main knock on Mothra is probably her stopping power and toughness—she’s always in the fight, but rarely does Mothra kick anyone’s butt. In fact, she tends to die in most of her appearances, but luckily there always seem to be one or two Mothra larva left over to become the new Mothra.
