Rayquaza has been one of my absolute favorites ever since I caught it on my Sapphire game version. I can remember climbing up the Sky Pillar in-game, and when I had arrived at the top floor, I wondered what the green mass should be. I soon found out I had met (and, after several tries, caught) another legendary. My class mates didn't believe me at first that I had met a new Pokémon XD I've always had one in my team since then, if possible. And the shiny version that was distributed in Germany in 2015 for ORAS made a dream come true!
Anyway, this green Asian-style dragon is extremely cool, strong and cute at the same time. I love the fact that it's designed as the ancient guardian of the planet earth, roaming around freely in the ozone layer, protecting the world from meteors and aliens from space and natural disasters that Kyogre and Groudon would cause.
