No. Zecrom is unavailable in Pokemon Black. You will need Pokemon White to get it.

None. Zapdos is not obtainable in Pokemon Black from the wild. You'll need to transfer it using the Poke Transfer or trade for it.
yes it is. Its in black and white. you need celebei to catch it. and its spelt zoroa
You can not catch Groudon in black or white but you can trade for it and for the other legendary pokemon! But you need really awesome pokemon to trade for them. Nobody gives out rayquazas or groudons or zekroms for nothing you know! I hope I helped!
there r no legendary Pokemon on the pokewalker
The only legendary that can be in an Egg is Phione, which you need to breed Manaphy with a Ditto. But other than that, you can't get any Legendary Eggs.
To get landorus you must have Tornadus (From Black) and Thundurus (From White) in your party and go to the Abundant Shrine where all the people are (or were).
This depends. What Pokemon are you trying to defeat? Try to get all legendary Pokemon.
Yup! You need to do a event to get it though! :(
Yes and no. You do need all three starters, and you need every legendary except for Deoxys, Celebi, and Jirachi.
TO Get A legendary Pokemon egg you need this code( action replay) hufhdewylfhaefhauebcue<wkdfn<vklrnhcuc<lknhe<unlrgft v<lkenhcuw4agtc734y57r8q
