Well, since I beat the Elite Four in Diamond, my mission has been to fill up my Pokedex. I've been checking on Pokemon swarms practically everyday now, and hatching some of my fossil Pokemon. For a while I left my Anorith and Omanyte in the daycare; now they're just above level 30. I also recently caught a Seel, Smoochum, Spinda, Natu, and Dunsparce.
Also, just last week, I decided to venture into Turnback Cave. For an even weirder reason I decided to try catching Giratina. This was a bit challenging, because Giratina was level 70 and most of my Pokemon were level 40-50 (I had one level 61 Pokemon and two low-level HM slaves). On the first attempt, I got Giratina down to about two HP and paralyzed it (I had my Raichu in my party), then threw about 20 Ultra Balls before Giratina KO'd my team. On the second and third attempts, I accidentally KO'd Giratina (my level 61 Ninetales was to blame). But on the fourth attempt, again my Raichu paralyzed Giratina, Ninetales cut its HP a little bit with Extrasensory, and Gallade used Leaf Blade to get its HP into the red zone. I threw an Ultra Ball and it failed. Gallade used Leaf Blade again. I threw a Timer Ball... and caught Giratina! Upon catching it, I nicknamed it Sauron. So now the Dark Lord sits in my PC. Mwahahaha. And, it's still my highest-level Pokemon...
Later, I caught Rotom with few problems. After that, I caught Cresselia, using the exact same method I used to capture Mesprit. Then I explored Route 224, battling trainers with a team of legendaries along the way... Oh, speaking of a team of legendaries, yesterday morning I was riding my bike past Solaceon Town, so that the fossil Pokemon I put in daycare would gain more experience. While doing that, a jogger ambushed me and demanded a battle. The battle was actually pretty funny...
Jogger: Go Ponyta!
Me: Go Sneasel!
Jogger: (thinking) Ha, Sneasel is Ice-type! This should be a cinch!
Me: Sneasel, use Beat Up!
*Darkrai, Cresselia, Deoxys, and Giratina come out and attack Ponyta*
Jogger: OH SHI-
*Ponyta faints*
