Millennium Puzzle Chosen one: Pharaoh-Atem-1990
In addition to holding the soul of Atem, the puzzle is able to fulfill one wish of the person who had solved it and heighten its owner's chance of success in a game, judging by their skill as well as the importance of the game at hand. It is also shown to have the power to interfere with the powers of other Millennium Items.
The Millennium Eye Chosen one:
It has the ability to read a duelist's minds and see through their eyes, allowing the holder to know what their opponents are thinking at all times no matter what. Its holder also has the incredible ability to seal their opponents' souls and remain trapped until the soul stealer is defeated in a duel.
Millennium Ring Chosen one: DiapyGirl (Sarah)
Its powers are to guide the owner to where ever he seeks, acting as a sort of compass. Its demonstrated abilities include sealing souls away, summoning Duel Monsters from the cards, and being able to devine the location of other Millennium Items. The Ring also has an unexplained bond with its owner and can't be lost.
Millennium Scale Chosen one:
It can weigh a person's heart against the feather of Ma'at, the goddess of truth. If a person lies while being interrogated by the owner of the scale, or is revealed to be truly evil, the side opposite of the feather will lower, as if weighted down by the person's sins, and if the side without the feather drops to the bottom, the person's soul will be sucked into the depths of the Shadow Realm.
Millennium Key Chosen one:
Its primary unique ability is its power to unlock the doors of a person's soul, giving the user access to alter a person's personality. The brainwashing process can be undone, when the victim touches the Key. It can make the user, and others, invisible, and may or may not allow them to sense any disruption. The owner of this item may also force images, scenes, or visions into the minds of others.
Millennium Rod Chosen one:
This item grants the holder the power of bending the wills of others through mind control, and also lets its user telepathically communicate with his/her servants.
Millennium Necklace Chosen one: Jaceftw13 (Star)
The necklace allows its user to see through time, offering glimpses of the past and near future - futures whose outcomes can only be altered through the use of other Millennium Items.
