Which area do you fight alder's grandson?

Question

I'm just wondering cause I want to fight him, also my friend told me that he would give you a shiny Pokemon with an Exp. share (sounds hard to belive.) is it true?

Edit: I'm talking about the White Treehollow Challenge in white forest

You don't need to answer the shiny pokemon part I found it out by myself.

Answer 1

>In Black City and White Forest, there are new battle areas known as the Black Tower or White Treehollow. These areas feature various trainers for you to defeat as you progress. At the end of the massive area, you will find Alder's grandson, Benga. His team varies based on which area you're in.
