Kefka was hit in the shoulder, chest and what remained of his upper right wing. The bullet from the rifle hit him in the gut and bowled him over. He got back up, and laughed.
The cosmic energies from Riou's Forgiver Sign knocked him to the ground with great force, trowing him several feet away. He shakily got ack to his feet, severely wounded, but still laughing.
The energy from Reimu's Fantasy Heaven blasted straight through Kefka gut, leaving him with several holes. Gwen's dark matter bombs blew Kefka's left arm away. Sara's fusion beam struk Kefka in the chest, scorching his flesh.
When EWa stood over him, he looked up at the sky, closed his eyes and spread out his remaining arm. He did not struggle, or even bothered with last words. He accepted his fate. EWa's Solar Flare desintegrated Kefka.
Once the intense light died down, the feather that he wore in his hair slowly floated down to the ground.
