Megaguirus (New Age of Monsters)

Megaguirus is a giant prehistoric dragonfly Kaiju that appears in Godzilla: New Age of Monsters.

Origin
Megaguirus was a mutant Meganulon created during a black hole experiment. Megaguirus was chosen by the other Meganula to be their queen.

Awaken
Megaguirus was in her cocoon in a submerged part of Tokyo as the smaller Meganula had gave up their energy for the queen and after receiving Godzilla's energy, Megaguirus rises up and went to hunt down Godzilla. When the mutant dinosaur made his way in Tokyo, Megaguirus appears and fights Godzilla. Although it seems that the Meganula queen was winning, Godzilla gains the upper hand by biting off her stinger and kiling her, ending Megaguirus's threat.
