BTW, in case you're wondering how someone could AR an Event Pokémon, I can tell you how. They collect the legitimate Event themselves then look at the coding to determine how to create the same Pokémon using Action Replay. What results is a perfect clone of the original Event right down to the very Ribbon; coincidentally, this Ribbon makes it uncheckable via PokéCheck. As legendaries cannot participate in certain types of activities, even the backup method of checking is impossible.
I do believe an AR code would be locked to one nature, so using the code may generate the same nature 100% of the time; otherwise, it works exactly like the Event. All one has to really do is change the DS date to match the period of the Event, run the code a couple of times, and there you go.
