User blog comment:Richard Starkey/Rayquaza Vs. Alduin/@comment-3361508-20120901161057

If we're still voting, I'm giving mine to Rayquaza. Even if he's not as intelligent as Alduin, if both of them fall to the ground or something, Rayquaza can zoom back into the sky in a second, whereas Alduin has to do blah blah blah and all that jazz. Also, considering it's in Sky Pillar and the surrounding area, Rayquaza would have the edge too. Sky Pillar is surrounded in water, and Rayquaza can go underneath the water, where as Alduin and all other dragons can't.
