It's kinda funny (not at your expense, Peter, I sincerely do not mean it like that) that all the names of the Weather Trio, the box legendaries of Gen III, are all mispelled, while the rest are perfectly fine. I was amused the most by "Krogiya", as Strike the Blood already stated (That would actually be a cool Fakemon name!), but I also found "Gourdon" amusing. Here's how it played out in my mind:
Me: Go, Gourdon, use Eruption!
:t383:: THAT IS NOT MY NAME, PUNY HUMAN!
Rayquazza is funny too, but it wasn't as interesting as the other ones...
ANYWAYS BACK TO THE POINT AT HAND
Deoxys is an awesome legendary in many ways. He was the first to pioneer alternate forms, paving the way for many other Pokemon to follow (the bulk of them coming from Gen IV). He's also the only Mythical Pokemon to become simply a Legendary Pokemon as the games went on, a la Omega Ruby and Alpha Sapphire, as if Deoxys took pity on the humans that weren't able to catch him earlier in the series. Quite a friendly compromise, considering that you have to get past Rayquaza to get to Deoxys in the first place, a fair trade I'm willing to accept. Those, and the fact that his theme is probably one of the best Legendary Pokemon themes out there, if not one of the best Pokemon tracks of the series for all time. These reasons are why Deoxys is one of the best legendaries in the series as a whole.
