Final Fantasy VII

Sephiroth: It's simple. Once the Planet is hurt, it gathers Spirit Energy to heal the injury. The amount of energy gathered depends on the size of the injury... What would happen if there was an injury that threatened the very life of the Planet? Think how much energy would be gathered! Ha ha ha. And at the center of that injury, will be me. All that boundless energy will be mine. By merging with all the energy of the Planet, I will become a new life form, a new existence. Melding with the Planet... I will cease to exist as I am now... Only to be reborn as a 'God' to rule over every soul.
