mispirit and volcano help!!!!

Best way to catch mesprit is to use a move on him which prevents him from running, like mean look or something or a Pokemon with an ability which prevents fleeing, like arena trap or something. With that you can trap him, wittle his HP down and put it to sleep or paralyze it and just keep chucking balls and continue putting the status effects on him. Have false swipe? Will make it much easier.

1)i suggest you go buy alot of dusk balls in solacen town and get out a Pokemon that knows sleep powder, hypnosis, or sing. Then go find it at night. 2) Go back to the volcano and go to where you got the treasure. Bring ultra balls. I recomend that you bring a Pokemon that knows a move that can put your opponent to sleep. Also if you go at night, bring dusk balls. When you get there, HEATRAN will be wating where th treasure was. Also make sure you have the national pokedex

Well to catch mespirit weaken it down to about red and yellow and use Hypnosis to make it go to sleep then try useing a Ultra ball and be patient this might take some time

And there's nothing much else to do fill up your National Dex this one has 400 and something Pokemon and fight at the Battle Tower and raise your Pokemon up to level 100

Sadly there aren't any more badges, I wish there were like in Gold/Silver version. Now about Mesprit...It wanders around and bolts the first turn of the battle. Quick Balls are recommended for such pokes, but try to outspeed and trap it with Mean Look or Block if at all possible. Those players without an infinite Master Ball code for the Action Replay raise a Crobat exclusively for this purpose. Now about hunting Mesprit down... Go somewhere close to a grassy route(Floraroma town is my favorite for snagging wandering legendaries)and find the border between the grassy route and the town. Then turn your poketch to the marking map(found at the poketch co.) and there should be the flashing head where Mesprit(or Cresselia, depending on how far into the plot you are)is. Now keep walking across the border and Mesprit(or Cresselia) should change it's location. Keep this up for a few minutes until the flashing head is on the route you are on,then walk into the grass until the Legendary Pixie Battle Theme starts up. If it runs, don't despair, just continue crossing the border and it should pop up again. If you could care less about Crobat, try a Quick Ball on the very first turn, when it's most effective. Depending on your General Luck Quotient(GLQ), you can catch virtually anything on the first turn if you chuck a Quick Ball at it. I got Dialga on my Diamond version with one of these. Technically there are currently 498 species, 492 of which are officially acknowledged, 493 of which are acknowledged on this site, and of the last five, one is new and the other four are new forms of Castform and Rotom all will be revealed on Platinum version next month. . -jbjbh signing out, Happy hacking;)

The best way to catch Mespirit is to make it go to sleep or something. Then try your ultra ball.

And if you want something to do, I should tell you that to complete the whole game, you need to complete the National Dex, Catch all the different Pokemon, level all the Pokemon up to level 100, then you can start thinking you've completed the game.

There are no more badges to get but you can go back through the volcano again and you can try to catch heatran. I would recommend the dusk ball for heatran. And as for Mesprit I would make sure to get her hp down but save your game before doing so just in case and just try to use different balls like the quick ball.
