Bonnifer never personally met Bowser; she was forged by an outsider foundry instead of one of the Koopa munitions plants. This crass Banzai Bill with little sense of personal space, is a loyal general among the Koopa Troops' naval forces; even if she intimidates even her highest ranking Hammer Bros aboard her ship with just her sheer boisterousness and flirty pushiness. Her famous scar is no more than a mishap from her forging; while her metal body's "presence" (fatness) is her own doing.
