Megaguirus was created when a weapon that would send Godzilla into another dimension allowed a giant insect to arrive on Earth and lay an egg which would later be discovered by a young boy and then hatch into a Meganulon. Megaguirus has numerous abilities. At top flight speed she vanishes into a blur, enabling her to surprise an opponent from an unexpected quarter. This high-speed flight also produces high frequency sonic waves capable of shorting out nearby electrical equipment. Her sharp wings can even cut steel and concrete. Her large abdomen ends in a vicious stinger used to pierce into an opponent's hide and drain energy from it. During this process, the opponent is incapable of launching any additional energy-based attacks upon her.
