>a black giant created by arceus to destroy an egg to release life>destroys the egg, but continues to destroy the life inside>palkia and dialga can't bring themselves to fight their brother so they choose a human to do it, creating the lake trio to help him>the black giant's body becomes the sky, earth and sea, and its soul becomes rayquaza, groudon and kyogreIt all fits with Giratina being "banished" for its violence, being a Ghost-type, residing in an ancient graveyard, and being associated with antimatter.
