No, Moltres cannot be caught in Pokémon White 2.
no
The proof is it is the Pokemon's "Catch Rate" The lower the catch rate, more balls miss. The higher the catch rate, the higher the chance the Pokemon will get caught. Moltres is hard to catch because it's catch rate is 3.
you catch them
can you TRADE for a pansear on POKEMON WHITE 2!
Yes
Technically, no. You don't catch White Kyruem. You catch Kyruem and catch Reshiram. Then the two merge together.
Catch kyurem,catch reshiram, and fuse them with the dna splicers
Imposible.............. Possible with cheats but, you can get it in pokemon black and white 2
Its impossible. The only way to get a moltres is to get it in pokemon leafgreen or firered and catch it on island 2 (I think). Then you beat both games (beat elite 4) and finish pokedex in pokemon firered/leafgreen. Once you did that, you have to trade moltres into emrald. You can only do this with gameboy SP's and regular gameboys, and you need a wireless connecter (or with wires, doesnt matter). thats the only possible way to get moltres in pokemon emrald. Hope it helps!!
You can't
You cannot catch Meloetta in Pokemon Black 2 and White 2. You have to receive it from an event, but as of right now, it has not yet been announced for North America.
Rufflet cannot be caught in Pokemon Black 2, you must trade from White 2 or White.
