yes at spear pillar
Dialga and Palkia are unobtainable in Black 2 (or any other game in Generation 5 (BW, BW2))
you can't really catch dialga on ruby, but you can use an action replay to get it because you can pretty much catch any Pokemon with an action replay
Yes, you can catch Dialga without a Master Ball. Dialga can be caught with any kind of Poké Ball but Dusk Balls and Ultra Balls would be the better options.
no but you can catch both Dialga and Palkiaalso you can catch articuno, zapdos, and moltres but so far i think you can only get certain Pokemon like in Diamond and pearl and the other old versions
Dialga and Palkia. You have to battle the Galactic Leader and then catch Giratina. They will be waiting at the spot where you catch Dialga in Pokemon Diamond. You will battle Dialga and then Palkia, both of them being at lvl 70. Be sure to bring some ultra balls or master balls if you have any. Hope this helps!
It would be Arceus but since Arceus is not available yet in any game, it would have to be Dialga and Palkia.
I'd recommend a master ball .I think dawn should've given you one. If you already used it then read the following: #1 The ball can catch any Pokemon at any lvl at any hp even dialga lvl 100 (it isn't really its 47) #2 you only get 3 in the whole game and you shuldnt have used it Hope i helped :D
I do have the mystery dungeon 2 and you have to beat the game (beat Dialga) to recruit any legendaries. Or, you can beat the game, beat Dialga to get Dialga, then the same for Palkia, but you never get to actually recruite them, I tried.
No, Dialga cannot breed with any Pokemon. It is a genderless Pokemon.
You cannot catch a tiranitar on any pokemon game, you have to get him from evolving Pupitar.
You can't catch any starter pokemon in any pokemon game. But you can trade them online via GTS.
throw a pokeball at it
