The Arcana Emperor (エンペラー) is one of two Shadows that appears during the third Full Moon in Persona 3, alongside Arcana Empress.
During the third Full Moon operation, the Arcana Empress and the Arcana Emperor are the two Shadows that attack Yukari and Mitsuru. The Arcana Emperor is a tall Shadow that carries a rather small sword. On its torso is a large red cross, and its arms are long and almost floppy, with small tassels at the end of its "sleeves". It has no neck or head, only a floating Emperor mask, identifiable by its signature purple color and spiked top.
Like the Arcana Empress, the Arcana Emperor is one of two Shadows capable of the stat-changing move "Paradigm Shift". However, instead of matching the Arcana Empress's weakness to all physical attacks, the Emperor is just the opposite, as it is weak against all manner of magic until it changes its stats.
The battle with the Empress and Emperor serve to demonstrate Fuuka's scanning abilities. Be sure to scan them after every time Paradigm Shift is used to determine the new weakness(es) and resistance(s).
As all Shadows appearing on Full Moon nights, its appearance and behavior are based on Tarot cards from the Major Arcana in the reverse position. It has the appearance of a large entity covered in armor fitted for a knight, it has a large chest with a large cross imprinted on it and a short sword, the emperor mask replaces his head.
As this is the Reversed version of the Emperor Arcana, it represents the dark qualities of the Arcana. The Emperor represents authority, the strong will of a king and the masculine side of the two genders, the Reverse version however is represented as weak willed, corrupt and rigid. This is represented by the fact the Arcana Emperor has a large chest and fights alongside the Arcana Empress -- it gloats of its power and superiority, yet it cannot fight without help. The small sword it uses also represents the weak will of someone irresponsible or one who doesn't make the right decisions as a leader. All of its movements are also very stiff, as if it forces every action out.
