Sorry, but there aren't any trainers with a Vespiquen in Pokemon Black 2. I guess you have to find it in the shaking grass in route 12 or Lostlorn Forest.
there are a lot of trainers who want to battle you there, and some Pokemon that you probably cannot see at any other places in the unova region.
The elite four, the champion, (Cheren, Bianca,you have to find them)and,(Cynthia,after you beat the game)
There aren't 'legendary trainers' in Pokemon Black/White 2, but there are 'special trainers' that are high-leveled and the strongest in the game. Some examples include Alder in Floccesy Town, Cynthia in Undella Town, Cilan, Chilli and Cress in Striaton City, Benga at the Black City/White Forest, the Plasma Frigate in the P2 Lab, the Shadow Triad in Icirrus City, and the GameFreak fellows in Castelia City. Most of these trainers require you to beat the game, though.
all Forget the previous answer and play black/white then black/white 2
It isn't in black 2 or white 2 you have to transfer it.
Find it in forums.cheatengine.org open flash games then the trainers and you will find it.
Go to the jam makers cabin on the union road and he has a quest where you have to capture vespiquen. Go to the jam makers cabin on the union road and he has a quest where you have to capture vespiquen.

Those 2 trainers are named Annie and Oakley.

In black 2 you get Zekrom, Black Kyurem, Latios, Electibuzz and get to go to Back City. I white 2 you get Reshiram, White Kyurem, latias, Braviary and get to go to White Forest. In Black City you can vs high level Pokemon trainers and buy more items and in white Forest you can catch some Pokemon that you can't catch in Black 2. The rest of the game is the exact same so you decide witch one is better.
This is random every time if you're talking about black skyscraper
