Well it is fairly EASY to catch if you get it down to a sliver of HP left.
DON'T USE YOUR MASTER BALL!!!!
NEVER USE YOUR MASTER BALL ON DIALGA BECAUSE YOU CAN USE IT FOR CRESSELIA LATER ON IN THE GAME
Don't use a Poke Ball but if your plays around Noon-7:30 pm use a Poke Ball, Great Ball, Ultra Ball
Use Dusk Balls in 7:30 pm-6:00 am Because they work awesomely.
FYI I was lucky enough to catch it in a poke ball but still don't try it unless Poke Balls are your only option
i don't know...but i caught dialga in diamond with an ultra ball so theres an idea
If you are in the 1st turn, throw a quick ball and it has a high chance of capture. If that doesn't work just throw ultra balls
use a poke ball
Either weakening its HP or using a Master ball, but i recommend you use a master ball.
Beat the elite 4, then you obtain the two fancy orbs from mt coronet, adamant for dialga and lustrous for palkia, go speak to the celestic towns elder. Then return to the spear pillar and you should see a blue portal
Type your answer here... where its snowing therer will be a cave that you need to use rock climb twice this will only work if your at the begging of mt cornet. oh and when you start it will be in the first snowing place
No, Dialga is relatively easy compared to the Pokemon in later levels and don't worry about your used Master Ball either. You can follow my Trainer Tip or use other methods to catch it, to say "I was given the Master Ball to catch {Mewtwo, Lugia/Ho-oh, Rayquza, etc.} and failed due to using it on another Pokemon" is like saying "Mew is under the truck and if I don't get it now I may never get it". With both they're several ways to catch them (Mew was never under the truck to begin with but is still obtainable through Glitch) and you can catch Dialga with the Ultra or other ball. Good luck d;)~ The Anonymous Pokémon Master.Total Caught: 487/487 + Shiny Complete.TRAINER TIP: A lot of people make the mistake of using the the Master Ball on Dialga/Palkia or other difficult Pokemon. I instead recommend using a regular poke ball (or a primer ball on Legendaries or shinies) immedietely, on the top screen when the ball opens to release it's light press the middle of the poke ball on the bottom screen. If done correctly you'll be able to catch all Pokemon without weakening with a 100% catch rate.Also there's been a rumor of being able to go to the Game Corner and winning a Master Ball.
ultra ball
a quick ball
The best Poke Ball to use on any legendary Pokemon is usually the Master Ball.
the best ball you could use is a master ball because it straight away catches it.
best ball is always a master ball but i would use a poke ball cause you meet at level 1 just teach faise swipe to a Pokemon use it and use a couple poke balls
The best pokeball to catch victini in white/black is the ultra ball or the great ball you shouldn't use the master ball.
Its always too hard to catch. But you can use a Master Ball right away or a Quick Ball. Occasionally, if its weakened, you can throw a lucky Poke ball at it. That's how I got my Dialga!
the ultra ball is what i used to catch it...but you could use the master ball after you get it
The best ball to catch Deoxys is a Master Ball or a Timer Ball! Trust Me!!! Pokemon Master
U can use a poke ball,mega ball,ultra ball but try it from the first when it appear with a quick ball it can catch it faster.
use a master ball
Once you have gotten far enough you will have to battle Cyrus at Mt. Coronet. After you beat all the people there you will get to battle dialga. I think this is your only chance to catch him so use a strong poke ball... but save the master ball for mesprit because it's hard to catch.
