u had to get through mount cornet and when u get to the top, u have to beat the three team glantic leaders then dialga will come b4 u battle them and u will have to fight it either catch it or kill it it's ur choice

Two: Rotom,

u have to first get the national dex (see 150 pokemon), and then go to the forest of the grass gym leader (it's south of the pokemon center) and make sure it's night time and gardina will be there and talk to her and use cut on the lil tree's and go into the haunted mansion and go to the second floor and go to the second to last room (the room that has  a tv) push a on the tv and push yes and there u will have to also bring max revies or revive, max reply, and ultra balls(tons of them)

Answer 3

Here I go! I'll explain legendaries you can get in the game automatically, many others you need to watch for events in your area.

1. Dialga- [Appears at lv 50] Mt. Cornet at the Spear Pillar area. I recommend not using your masterball...

2. Uxie- [Appears at lv 50]  Your return visit to Lake Acuity by snowpoint city [you must know surf]

3. Azlef- [Appears at lv 50] Your return visit to Lake Valor by the Valor Lake front [you must know surf]

4. Mesprit- [Appears at lv 50] Your return visit to lake verity by twinleaf town. [You must know surf] This pokemon wanders after you see it so be prepared for an annoying time... check the marking app on your poketech for where it is.

5. Cresselia- [Appears at lv 50] In Canalave city talk to the sailor's wife in his house and she'll tell you about her son and his nightmares [Darkrai reference there] Then talk to the sailor and he'll take you to Full Moon island, you'll run into Cresselia then it will roam the land as well...

6. Giratina- [Appears at lv 70] Along spring path; you must know rock climb. Spring path is located south of Veilstone City.

7. Heatran- [Appears at lv 70] You'll have to go through Stark Mountain [in the battle zone island area] twice; the second time it will be toward the top for you to catch.

8. Regigigas- [Appears at lv 70] You must transfer all three Regis [Regice, Registeel, and Regirock] from either Ruby, Sapphire or Emerald. [You must have the national dex to transfer] Then in Snowpoint City there should be a temple; you'll be allowed to go in after you get the National dex. Make sure to have the three Regis in your party then you go to the bottom and the big guy will be there.

Tips:

For all but Mesprit and Cresselia be sure to save before going up to the pokemon and hitting A... VERY important in case you KO it or run out of poke balls. Bring about thirty ultra balls and a few timer balls. Just keep its HP low and try paralyzing it or putting it to sleep. That should make it easier to catch. If you saved your masterball, it will come in handy for one of these guys, as it never fails, just throw it at the beginning of battle.

For Cresselia and Mesprit- If you do run into them they are subject to flee; if you're looking for them it really helps to have a pokemon that knows mean look and hypnosis. If you run into one do not switch out pokemon or they will flee; so try keeping like a Haunter first in your party, first use meanlook which prevents the pokemon from fleeing, then use the same technique as above. But remember; if you defeat it you will hae to search for it again. And also note meanlook only works on the pokemon that used it; so if you switch the pokemon then it is subject to flee. For these pokemon I recommend always having about thirty ultra balls handy.

Those are the legendaries that you can catch in the game. Hope it helps; if you have any other questions I can most likely answer it.
