Robin Hood is a heroic outlaw in English folklore who, according to legend, was a highly skilled archer and swordsman. Traditionally depicted as being dressed in Lincoln green, he is often portrayed as "robbing from the rich and giving to the poor" alongside his band of Merry Men. Robin Hood became a popular folk figure in the late-medieval period, and continues to be widely represented in literature, films and television.
Robin Hood fought against the evil Sheriff of Nottingham who was loyal to Prince John who had stolen the throne from his brother, Richard. Later stories introduced the Guy of Gisbourne, an assassin sent for Robin’s head who eventually became part of a love triangle with Marian.
Robin Hood is Goro Akechi's Initial Persona. As later revealed, he is not Goro's only Persona, he being a Wild Card has his other Persona Loki, who he switches to after being annoyed enough in his boss fight.
