What is your favorite Story Legendary Pokemon? Mine would have to be Ho-Oh and Lugia. C:

NOTE: Sorry if I forget any of them. Just let me know if I forgot one. C:

Dialga, Palkia, and Giratina, although the weather trio came in close second.

My opinion is the exact opposite of the above poster: the weather trio's story is the best out of them all, but Dialga/Palkia/Giratina come in very close, second position.

I agree with Shadow, the Weather Trio's story is great. The Dragon Trio is right behind them.

As for the Lugia and Ho-Oh story, I didn't even know they had one. And the Zekrom and Reshiram story I really know nothing about. :V

Yeah, Ho-oh/Lugia really didn't contribute to the games' story much, if at all. The others all played a part in creating the Pokemon world and are sought after by the evil team. Team Rocket didn't want Ho-oh/Lugia at all, and all they created were the legendary beasts/birds.

I'd say my favorites are Palkia, Dialga and Giratina, followed by the weather trio. Cyrus' whole "using Dialga/Palkia to destroy the world and recreate it with me as god" thing was perhaps my favorite evil organisation grand scheme yet (when I play Black/White, that may change), and the fact that Dialga/Palkia/Giratina created the fabric of the universe and are considered gods is a bit more interesting than "just" creating the oceans and land, or ruling the atmosphere or whatever Reshiram/Zekrom do.

What everybody else said.

Space, time, antimatter and the Creator. Satoshi Taijiri really hit the sweet spot with the Sinnoh story.
