Question

Where can I find a Pinsir for my pokedex in black 2?

Answer 1

Pinsir can be found in Lostlorn Forest's Hidden Grotto, with a 0.75% chance of spawning. This is so low that it might be faster to get a job, earn enough money to pay for a copy of White 2, wait for it to ship, and play until you get to Route 12. Have fun!

If you're just looking to see Pinsir, it can be found under the ownership of Backpacker Reece (Route 14), Veteran Murphy (Lostlorn Forest), and Black Belt Martell (Victory Road).

Answer 2

I'm sorry to tell you this, But the Only way to add a Pinsir to your Pokedex is by Trading, It is exclusive to white 2 (Out of the two games) like Heracross in In black 2, yet not in White 2, So you can only Obtain a Pinsir by Trade. I would suggest asking a friend who either owns a copy Of white 2, Or A Friend who has a Pinsir in another game, I suggest asking them to trade with you. If you do it v.i.a. White 2 here is a List of where your Friend can find and catch a Pinsir for you:

Route 12 (Light and Dark grass) (Not in Rustling grass)

Lostlorn Forest (Light and dark grass) (Not in rustling grass) (Not in Water) (Not in Water/Rippling Water) (In Hidden Grotto at back of forest)

I hope this helped you Connorg123 :)

Answer 3

You can find Pinsir In a trade, because White 2 gets Pinsir and Black 2 gets Heracross, aside from this, there is no other way.
