Diarkrai is lvel 900
Edit: You retard, there are no level 900 Pokemon.
yeh,stop lieing!
After you get the national pokedex you can see, catch and record all of the Pokemon in the world (instead of just all the Pokemon that occur in the sinnoh region).
Once you have battled somebody with a non sinnoh Pokemon it will be in your pokedex and sometimes your pokedex will tell you where in sinnoh to catch it.
However, you often need your poke radar to get them (Ralts is a good example.)

Written Description:
The National Pokedex is a handheld encyclopedia that gives you information on Pokemon around the region. In HeartGold and Soulsilver Versions, the National Dex gives you in all 493 descriptions on every Pokemon found in Kanto and Johto. This Pokedex is given to you by Professor Oak before the Player boards the S. S. Aqua for the first time. Once this is completed ( Any unobtainable Legendary Pokemon are not required for completion.) Professor Oak in Pallet Town will congratulate you and award the Player with a picture with Professor Oak. After doing this, in the Game Freak section in the Celadon Condominiums, there will be the Employee who rewarded you with a diploma for completing the Johto Pokedex, talking to him again will lead to another given diploma, with Legendary Birds Ho-Oh and Lugia.
