How do you get Mesprit in Pokemon Platinum?

Answer 1

This is how you get the legendary Pokemon Mesprit.First you finish all your work at Distortion world. Next, go to Twinleaf Town. Then go to route 201, and go left and get to Verity Lakefront. Then go inside of the Lake. Then SURF to the middle of the lake, and you will see an island. Go inside, and talk to the Pokemon inside, Mesprit. It will show a picture, and will leave. Then the professor will come in and say stuff about the Marking Map, which is a poke-touch app that marks legendary Pokemon that flee. Go get the Marking Map, and get to the route Mesprit is on, when he is there. Then find him (You can use repels and a Pokemon less than level 50, or just find him). If you want to weeken him, but catch him in the same battle, get a fast Pokemon with Mean Look, or Block. This keeps wild Pokemon in battle. Mesprit is very fast though. He also has the nature on his side, so it is even harder. Then you just try to catch it with pokeballs (Any type of pokeball). He is an 16% I say with using the Master Ball.The other pecents of the master ball useings is here (What I think). All of these are for non-event legendary Pokemon.Mesprit: 17%Cresslia: 17%Articuno: 20%Moltress: 20%Zapdos: 20%Girintina: 2%Dialgia: 1%Palkia: 2%Heatran: 1%The fleeing ones are Mesprit, Cresslia, Articuno, Moltress, and Zapdos.Hope this helped.
go to the lake by your home town, and surf to the middle. you will see a cave. enter it, then talk to mespirit. unlike azealf and uxie, mespirit will flee. it now becomes a roaming Pokemon. (in case you don't know, a roaming Pokemon is one that you can see at random locations, except caves, that will flee after 1 turn, but can still be chased after it flees.) you can get the marking map to track it at jubilfe city.

note: this can only be done after you exit the distortion world and battle giratina.
