No, you cannot find or get a Shuppet in Pokémon Black 2 and White 2 without hatching one but you can find Shuppet's evolved form, Banette in the Strange House and Victory Road.
Shuppet cannot be caught on white or black. You have to trade it from another game ^ You can actually capture Shuppet on White & Black versions. I found a couple of them on Route 13, if I remember correctly, I found them at nighttime. Other Pokemon can be found there such as Absol,Drifblim,Solrock, and Lunatone. Shuppets will usually be low-level, I think around 12-30. <-- I might be wrong. Hope this helped!
There is no reason Shuppet shouldn't evolve at Lv 37.
You can find Paras Mankey Farfetch'd Doduo Exeggcute Sentret Yamma Pineco Houndour(Black) Smeargle Tyrouge Poochyena Smroomish(Black) Plusle(Black) Minun Volbeat(Black) Illumise Shuppet Wynaut Hippopatos Croagunk :) Hope that helps
Gheisis is in the Black City if Pokemon black, or White forest in Pokemon white. In Black he is dressed normally, without the robe or the staff.
White...
No.
no without trade or transfer
You can't get mightyena in black without trading. In white you can catch a poochyena and evolve it, but you have to beat the elite four.
No, but the Black and White button thing works really well.
Without black and white 498 or 499 and with black and white more than 550. Actually without black and white its 493 while with the unova region games its around 646 if you don't count the three that haven't been released.
no
You can't without trading with someone that has black.
