Despite the success & popularity of the series, the pilot episode has never been aired or released.
The only known evidence of this pilot's existence is footage used in a Fox Kids promo where footage was used showing a few scenes that aren't seen in any other episode of the show.
Differences from the pilot and series shows that the art-style used in the pilot was less anime inspired and used flatter colors. Alex wasn't Hispanic either.
