Trivia
- It was shown multiple times that the use of Legendary and Mythical Pokémon is allowed in this tournament, which may be a reference to the change in rules in the 2010 Video Game World Championships. However, the real-life championship's rules does not allow Mythical Pokémon, meaning that Tobias's Darkrai would not be permitted.
