After the destruction of the Origin Sanctum, Maxim had to go and find a new arena to house his gym. He wanted it to be bigger and better than ever before, and so he went searching for some way to boost his Normal types through the roof. Eventually, he got in contact with the Kalos scientist Dr. Zoran, and agreed to fund Zoran's research if he would build Maxim an arena. Zoran decided to build two, and this was his second concept.
This is a virtual arena, and if chosen will be built near Turnback Cave.
You reach a small hut in the woods near Veilstone City in the Sinnoh region. You've been searching for the ASB Normal Gym for a while now, but haven't had any luck finding anything that looks like a gym. Wanting more leads on this elusive gym, you knock, and what seems to be some kind of servant answers the door. "Hello? Ah traveler, you must be tired from your journey, come in and rest for a while." Grateful for the offer, you head on inside, and then you sit in a chair facing the servant. It seems rather small for a living space, in fact it seems to only house the servant himself. Upon asking about this he replies "Oh, I see the confusion, my friend is out right now, he's waiting for a challenger to his gym. Figuring this must be the gym leader you seek, you ask where he is, expecting to have to fetch him to battle him. The servant's eyes light up and he says "Oh so you're the challenger. Excellent, my master is waiting for you just this way."
He leads you down into the basement of the house, where you see a really strange sight, a portal to what seems to be another world. The servant motions for you to step inside, telling you not to worry, as that's where the gym is. You step inside and find yourself in another dimension in front of a large building, the doors of which automatically open. Inside you find Maxim.
"
Ah hello there. You must be the challenger I was told about. Welcome to the Reverse World and my very own Inverse Coliseum. I trust you didn't have too much trouble finding this place. In truth, it's a bit difficult to give directions to this place, but at least you made it. In this arena, there is one rule and one rule only. All type advantages and disadvantages are switched. Simple right? I warn you though challenger, this is not going to be an easy fight!"
Summary:
This is an Inverse Battle, all type advantages and disadvantages are swapped.
