Lol, I'm actually somewhat greatful Dialga and Palkia are easy to catch. I remember the first time I played gen 4 I thought they were going to be a ***** to catch like Kyogre was in my Sapphire game. They weren't. Storyline legendaries I have no problem with being easy, but extra's like Giratina, Heatran and the like can be the "waste a half hour chucking ultra balls at them" hard catches. Giratina in Platinum version was much harder then Dialga and Palkia.
Parena or Serecham both equal Serena+Pancham!
