Retro had a much
stronger focus of story - telling with a planet split in two; a light
world with peaceful inhabitants and a dark
alternate with an evil species called the Ing.
These
alternate / new DLC characters are Afro Luffy, Kung Fu Luffy, Doflamingo and Trafalgar Law from their duel at Dressrosa,
Strong World Ace,
Strong World Shanks, and Zoro with torn clothes.
