About the Portals.

As for the portals... It has been unanimously decided that instead of fighting pokemon in the portal places, you will instead fight the inhabitants of the portals. For example, someone walks into the portal for some intense training maybe in the volcano place. You will fight some fire people. Do not expect it to be easy. Depending on what the fire person says to you, you might be able to learn some new jutsus or may just give you a good piece of information... But again, do not expect it to be easy. Think of it as an epic battle. The inhabitants of the portal may not be friendly and may not teach you or give you anything. Hell, you might even have a mission where you are supposed to go into those portals, who knows? The Portal inhabitants will also only be portrayed by the Kages and Sannin, so... yeah.
