10 Necron (Final Fantasy IX)

Through both its name and its appearance, Necron serves as the personification of death. It’s capable of destroying life with relative ease and has a strong arsenal of physical and magical attacks with which to do so. Though its physical form can be defeated, its essence will continue to linger on for as long as life itself continues to exist.

After careful observation, Necron concludes that the meaning of life is to seek death and so decides to destroy the crystal of life in order to revert the world to a state of perpetual nothingness and free humanity from its struggles. Unfortunately, however, it fails to take the party’s will to live into consideration and they’re able to defeat it in battle with a little help from Kuja.
