Well since you are a Pokemon hacker, would you like to be a minor "character" inside my Pokemon hack in a Gym? I got an inspiration from this:

So, would you want to be a "battle trainer" in my hack? You may list down the the phrase you wanna say and Pokemon you want to battle with the main character in my hack.
Example: *You caught a trainer*
You: Hi there, you might know me. *starts a battle*
Pokemon Hacker XXX would like to battle.
After battle: That was fun!
Oh, and have a nice day~
