The Rayquaza is a special Pokemon because for one thing it is the first legendary Pokemon on the list. This creature is essentially a dragon. However, it lives not on solid earth, but in the ozone layer and this is a good thing too, for from up there it is very useful as a fighter of foreign threats. Because of its extra-terrestrial abilities, you must depend on Rayquaza to protect the planet. Rayquaza is also useful because it can keep two deadly enemies in check, namely Kyogre and Groundon. Given this feature of Rayquaza, no one deny the fact that this Pokemon is a must-have on playing teams.
