after you save the three of them from team galactic, go to the cavern and see mesprit. it will leave. It will now rome around the region and you have to track it down using the poketch app "marking map" and catch it in the grass with the normal wild pokemon.
they are the three legendary trio of lakes they live in three lakes azelf in lake valor mesprit in lake verity and uxie in lake acuity
You find him like Azelf and Uxie, at their cave except Mesprit will disappear when you talk to him/her(which ever gender you prefer).So don't bother saving your game. To battle him just look at your town map and Mesprit's face will be somewhere. But you should walk there be if you fly his location will change.I found him looking for a different Pokemon find the easiest way is to just look for different Pokemon and hope to find him/her (which ever gender you prefer) randomly.
A Mesprit is a Psychic-type legendary Pokemon found in the Sinnoh region. It lives in and looks over Lake Verity - also located in Sinnoh. It is one foot tall and is coloured grey and pink. The pink parts are on its head and are shaped into four ear-like flaps that fall to the side of Mesprit's head. The Pokemon has small feet and two tails, both adorned with one small jewel. This same sort of jewel is placed in the centre of Mespirit's head, between its half open eyes. (http://bulbapedia.bulbagarden.net/wiki/Image:Art-Emurit.jpg - an image of Mesprit)It is said that after Arceus created Dailga and Palkia, it created three small Pokemon; one of which was Mesprit. Mesprit is known as the Being of Emotion - "it taught humans the nobility of sorow, pain and joy."Mesprit is a Pokemon available in Pokemon Diamond and Pearl. It is able to be caught after the player defeats Cyrus atop Spear Pillar and visits Lake Verity.
You can get them at the lake's. they are lake verity lake valor and something else. mesprit is a roaming pokemon, which means that it roam's around sinnoh, and you can track it's location using the marking map pokeketch app.
somewhere in the second cavern of stark mountain, on the left somewhere. But overheat lowers sp. attack harshly, so i prefer flamethrower(fuego ironworks) or fire blast (surf to grass area at lake verity).
go to lake verity,swim to verity cavern, and it should be standing somewhere... good luck!
You can find Mesprit in Verity Cavern. Head to Lake Verity and use surf till you find a cave. Inside will be Mesprit. However, it will run away so you will need the Marking Map app to find it.
To catch Mesprit you need to surf to the middle of lake Verity. There you will find a cavern in which Mesprit lives. After you talk to it, it flys away! When that happens, Professor Rowan talks to you. After he leaves, get out of the cavern and start chasing Mesprit! To chase Mesprit, use your poketch app Marker Map to find Mesprit's icon(it blinks!). Instead of flying to the nearest city, which makes it run away, walk or bike all the way to its icon and look around in the nearest patch of tall grass. it often runs away, so be careful!
it's in lake verity
You get it by going to one of the 3 lakes and into the caves. I think you have to do some stuff before they apear in the caves. Azelf- Valor Cavern Cave found in center of Valor Lake by Pastoria City and Sunyshore City Mesprit- Verity Cavern Cave found in center of Verity Lake by Sandgem Town Uxie- Acuity Cavern Cave found in center of Acuity Lake by Snowpoint City Hope that helps!! =D
Pokémon Diamond, Pearl, and PlatinumThe lake guardians each live in the cavern at the center of one of Sinnoh's three commonly known lakes: Uxie resides in Acuity Cavern of Lake Acuity, Mesprit resides in Verity Cavern of Lake Verity, and Azelf resides Valor Cavern of Lake Valor. A secret fourth lake exists, but instead houses Turnback Cave, which contains a portal to the Distortion World and is thus often visited by Giratina.
mesprit is at the descon wold and then it will be at verity lakefront and then it will start going around sihhoh in Pokemon platinum
There are many legendary Pokemon in Pokemon DP. Dialga/ Palkia(depending on the game version): First, head for the Galactic HQ in Veilstone City and find the boss and battle him. Next, head to Mt.Coronet through the Hearthome city entrance. Find the Spear Pillar and Dialga/Palkia will be there. Uxie: In Acuity Cavern, the cave at Lake Acuity. Azelf: In Valor Cavern, the cave at Lake Valor. Mesprit: In Verity Cavern, the cave at Lake Verity
The 3 Lakes (Verity, Valor, Acutiy)
you have to go to lake verity cavern and catch it.
After you've defeated Dialga, you go to Lake Valor or any other lake, you surf to a cavern in the middle and in there you will find Mesprit.
