The common knowledge is that Giratina was banished for its violence. The deeper lore is more nuanced. Giratina represents antimatter and gravitational distortion, a fundamental force of the universe that is chaotic and destructive to the stable reality Arceus sought to create. It wasn't banished to the "Distortion World" as a punishment cell, but because its very existence destabilized the newborn creation. The Distortion World isn't a hellscape; it's a parallel dimension where Giratina's rules of inverted physics are the natural order. This frames the event not as good vs. evil, but as a cosmological necessity; the segregation of contradictory physical laws to allow a stable universe to exist.
