User blog comment:Richard Starkey/Rayquaza Vs. Alduin/@comment-3528601-20120813161116

Gonna go with rayquaza for this one. While Alduin is more intelligent, I really think that's his only big advantage. Rayquaza has a lot more variable attacks, and he can freeze an 11-foot tall behomoth weighing over a ton with one shot from ice beam. That only seems to be one major advantage. Hyper Beam easily outmatches any dragon shout and is powerful enough to destroy skyscrapers. Rayquaza is also much stronger physically, being a lot stronger and faster. And for a world-ending god, Alduin is kind of a pushover. I had more trouble with Morokei than the final boss. Also, I guess all of rayquaza's dragon type moves would be super effective against a dragon like alduin. The one thing I'm really worried about would be frost breath, which would a balls load of damage against a flying/dragon, but Rayquaza could do the same with ice beam, and overall, the move frost breath does have overall less power than ice beam, so ice beam is still a massive hurt against what would be a dragon/flying type. Overall, Alduin is smarter, but Rayqauza will eventually overwhelm and overpower him.
