Super Smash Bros. Lore!

This is not official, it's some weird stuff made up by me and my friends

Origin

The universe was created by Sephiroth as a way to escape the IPP, which had been pursuing him after he assassinated the Galactic Emperor. When Sephiroth created the universe, he created two powerful beings to keep the world in balance: Kirby and Jigglypuff. Kirby, despite being known as the "Pink Demon", rules over the Three Heavens. Jigglypuff is the Anti-Kirby and rules over the Nine Hells.
