It often appears as the final triumph arcana, creating miracles and aiding the protagonists. Portrayed as a young woman (or an androgyne, depending on deck) surrounded by figures of an angel, a bull, an eagle and a lion (representations of the four elements in transcendent form, as well as the symbols of the four Evangelists (Luke, Matthew, John and Mark respectively), The World Arcana is a representation of the world's totality, the symbol of fulfillment, wholeness and harmony.
The World Arcana is commonly associated with Social Links, where its power is based upon the protagonist's bonds with others.
The player can guarantee a fusion accident resulting in a World Arcana persona by starting from a "hard reset" (as in, not already mid-game and loading a save or selecting "Return to Title") and performing a White Fusion after taking exactly 216 steps in an area where no enemies will attack, such as the Mikage Sun Mall.
The protagonist of Persona 4 can gain access to a Persona of The World Arcana in the events of the True Ending route, Izanagi-no-Okami. Through the bonds of the others, the World Arcana channels its powers to the protagonist's initial Persona, Izanagi, and transforms him into Izanagi-no-Okami.
The P3 hero and P4 hero are the sole users of the World Arcana in Persona Q. After defeating Margaret in the "The Power of the Wild Card" request, Orpheus and Izanagi will be reborn into Messiah and Izanagi-no-Okami; both Personas representing the World Arcana.
The protagonist of Persona 5 gains access to the World Arcana towards the end of the game's True Ending. It is received from Igor and Lavenza as a farewell gift after defeating the Holy Grail's true form.
Unused game files in Persona 5 indicate that the World Arcana was planned to be a fully functional confidant in the game, but this was scrapped in the final release. It allows free stat adjusting of Personas of the Arcana, and was intended to be able of being doubted (reversed) or broken. If it is doubted or broken, it will prevent the protagonist from adjusting the stats of World Arcana personas.
