I never got emerald, but before they released it, I thought they were gonna have another team that wanted raquaza, like team aero, or something to do with the air. Maby the pink haired dude is Cyrus' brother, and started his own team that wants Palkia, while Cyrus' team wants dialga (since his "brother" has pink hair and he has blue hair). But near the climax, both teams realize that they need Giratina to complete their "universe," and they both try to capture him. I don't know what they would want to do with time or space, but it sounded good when I was unraveling this idea in my head and typing it. Yes, I have problems.
Couldn't think of anything better to put here, so... yeah...
