Ishizu Ishtar

Ishizu is a main character in the second season of Yu-Gi-Oh: The Abridged Series. She is the bearer of the Millenium Necklace, and the older sister of Marik. Due to the Millenium Necklace's powers, she has the ability to see into the past, present, and future, as well as break the fourth wall. Despite her claims of these abilities, it's pointed out that she often does foolish things anyway, meaning she's either lying about having powers, not using them, or (perhaps most likely) just as stupid as the rest of the cast. She was given the Egyptian God cards by Pegasus and then went and immediately lost two of the, then she gave Obelisk the Tormentor to Kaiba, and became a finalist in the Battle City Tournament. 
She also appears to be racist, making many derogatory comments about Jews.

Though only appearing a few times thus far, Ishizu likes the expression "because, shut up" often in reply to people questioning her prophetic abilities.
