Longer summary: The levels of the Pokémon and the PP of the moves will not be explicitly shown (though they are all at a presumably high level). Their abilities won't be shown, but won't be the "hidden," for I'm not going so deep, and if there are two possibilities then the battle will reveal which one. The movesets aren't listed either, but will still be a "max of 4" for each (so should sooner or later be fully discovered). And all the moves should be something the respective Pokémon is able to learn, either by level up, TM/HM, though I don't really do much breeding nor battle competitively. But to make things more interesting, I will "create difficult turns for the player," so to speak.
It has been a long time after Archie and Maxie have returned the orbs to Mount Pyre. The player/character has beaten the league, and even beaten Stephen at the cave. It has been much more peaceful, for other than the "regular battles" against wild Pokémon and trainers, neither Team Aqua nor Team Magma has been appearing much. Even if they appear and are sited, the members are just traveling around like typical trainers, not causing any hazard, and even though people still fear them, there has been very little trouble, and all the members, administrators, and leaders, are becoming more and more like "regular trainers". As a matter of fact, some people have questioned themselves and other people, "How come these guys aren't like they were before? Are they different people who looked like the previous guys but happen to be wearing the same suit?"
However, one day the player flies to Lilycove city, planning to purchase a few items at the market and also get a lottery draw. Going from the Pokecenter to the market, he* finds both Team Aqua and Team Magma simultaneously. There are a number of other people, neither part of Team Aqua nor Team Magma, but all seem to be frightened. There are two rows, with Team Aqua on the left and Team Magma on the right, and a total of 5 Grunts, 3 Admins, and the leader of each team. All the Team Aqua members stand side by side to each other, and all the Team Magma members as well, with each person facing another of the other team, and "one space between each pair", with the leaders next to the market. The center leads to the market, but nobody is going to the store, for to enter they must go past the entire teams here, including Archie and Maxie. This time, there is nothing about the "summoning"; instead, Team Aqua and Team Magma are quarreling about "which team is better". The player approaches them, and when they recognize him* they pause, make a glance at him, but soon continue quarreling. The player hears a little of what they are saying, and as each member prepares for a nonuple battle, the character asks them, "Why were you arguing against each other?"
Magma Grunt (1) replies, "Team Aqua thinks they are the best! Can you believe that?"
Aqua Grunt (1) says, "What? Our team is far superior compared to Team Magma!"
Magma Grunt (2) says, "Then we shall see! Don't cry when you lose!"
Each of them has selected the first Pokémon they will send out and is holding the pokeball in their hand; at that the player requests in a little sad expression, "Please don't battle. Just separate for now, and everything will be fine. Just stay part of your own respective team…"
The character has noticed that if they really do battle, their anger, relentlessness, and recklessness (battling but not paying attention to anything else) will severely damage the city, perhaps even obliterating the place and destroying the market and other buildings.
Aqua Grunt (2) says to the player/character, "No, we are going to battle! You (the player) be the witness and later testify which team is better!"
Again, the character says, "Please don't battle..."
Magma Grunt (3) says, "Whether we battle is none of your business!"
Aqua Grunt (3) says, "Let's get rid of him (the player)! Then we can battle against each other!"
At this, the character automatically moves forward (up) between the first two Grunts...
