Hey, I know this is Pokemon. I involve them all the time in my posts. And your right and all about Pokemon being able to rip him to shreds, but Zack has Pokemon too. It would be like the roof top battle, Pokemon fight Pokemon, people fight people. Anyway I said I might do this, not I would, it was just an idea. (Yes, a stupid one, like all my ideas)
I'm not making Zack a villain mainly because, well, I don't want him to be, but also because of how Nion turned out after attempting being s villian. Kinda sucks.
