Blake with a gun makes sense, given that he is a member of Interpol in the manga. of course, in the world of pokemon, guns are a lot less practical than using your Pokemon, but using them together, I can see many possibilities opening up. A human is protected by their Pokémon during a battle, and you have to be commanding your Pokémon, so using a gun while in a battle is tricky. But maybe if you were a sniper and were using an earpiece to command your Pokemon to expose your target from behind cover.
