Pandora, the Big Three, Biorete, Cheshire, and the pirate travel thing.
After the Holy War, Pandora, the God of Reincarnation, was bored one day, so she broadcast travel information in the underworld, gathering idle people in the underworld to destroy the pirate world everywhere.
Note: Poor writing, this is a time-travel of LC, Pandora comes from "[Saint Seiya] Violence Code".
