Marik Ishtar vs. Itachi Uchiha
Marik Ishtar vs. Itachi Uchiha
While Itachi does Tsukiyomi to Marik...he doesn't realize two people in habit the body, Marik breaks out, and send Itachi to the shadow realm. Or Yami Marik just lets Marik get destroyed by Tsukiyomi, takes over body, send Itachi to the shadow realm after he challenges Itachi to a game that Itachi is destined to loose because only Yugi can defeat Marik. Even though Joey came close.
That would still be close. Cause he didn't win even though he had Marik wide open.
And really..even with Ra, seeing how it's just a card these days, he should still loose. Unless the fact that two souls are in Marik's body can break him out of Tsukiyomi..but he doesn't have the whole manipulate chakra thing.
In the anime, Millenium Items could make the monsters real like when Bakura uses his Ring to summon that Man-Eater Bug to take out Pegasus' goons.
Also, Yami Marik and Pegasus both said the monsters are real in Shadow Games; that whatever happens to you in one of them happens to you in the real world.
I really don't like Yami Marik though. Regular Marik was cooler.
