When you start the game at Destiny Islands you can fight Tidus, Wakka or Selphie. On the first day if you speak to Tidus, you have to refuse fighting him.

If you keep saying "no", he'll then say: "You'll never be a star in our game like me". Obviously this is a reference to blitzball and the fact that Tidus is a star player in FFX.

The reason Missngno. appears is because when you talk to the Old Man, the game puts your name a value in the data buffer place of where Pokemon are. The side of Cinnibar Island has no values for Pokemon, so it takes the data of the place you last were, which now would be your name. So now the game would load the hexadecimal values of your name for a wild encounter.when you enter a wild battle, and game tries to load a value that isn't a Pokemon (Your name), the game's error handling system causes a sub-routine when triggers Missingno.
