I'm glad this has been renamed, now I can think about League battles or rival battles for the other two main characters. Yays!
Since someone did one for Ash vs Iris, I'll do the one I did in the next gen thread but with detail:
Ash vs Iris 6 on 6
Unfezant (Calm Minded, a nicer version of Noctowl) Leavanny (The overlooker of the team, carer and clone of Pikachu) Palpitoad (Power-crazed and thirsty for battles) Cubchoo (Crazy and sneazy) Litwick (Shy and full of mischief) and Scrafty (Looking to settle a score) vs:
Haxorus (The main man of this team who is settling a score) Excadrill (The original pokemon) Emolga (Spoilt but hilarious) Zweillous (Powerful, a good friend for Haxorus) Mienfoo (Agile and full of focus) and Druddigon (Old fighter with new wounds to create).
Litwick vs Emolga-A diversion of fire and electricity. Reminds Drayden of the two legendary dragon pokemons. Starts talking to Cilan about it. Emolga is using acrobatics to score some hits while Litwick is defending itself with overheat. Litwick is tired but overwhelms Emolga with shadow ball.
Litwick vs Zweillous-Litwick is recalled due to typing and being tired.
Leavanny vs Zweillous-Leavanny uses string shots to keep Zweillous's heads together and it cannot control it's actions. Zweillous uses dragon pulse to gain free but by this time, Leavanny has landed a couple of X-Scissors. Zweillous is tired and Iris hatches a plan on defeating most of Ash's pokes.
Leavanny vs Excadrill-Excadrill lands focus blasts and metal claws while Leavanny is then told to use string shot across the field and then razor leaf. Drayden notes this is tactical and clever. Excadrill then finishes Leavanny off with Drill Run though cannot control it's movements due to the string shots.
Unfezant vs Excadrill-Excadrill cannot get to the aerial Unfezant and cannot move around the string shots. Unfezant lands some impressive sky attack's and recharges with roost. Excadrill however brings it down with focus blast and manages to use slash to keep it down. Ash then remembers who wants a big battle and decides to take a big risk.
Palpitoad vs Excadrill-Immediantly, Palpitoad laughs at the idea of this battle while Excadrill focuses. Palpitoad pays no attention to the strings and uses hydro pump across the field, hitting Excadrill and making it slippery. When it tries to get up, Palpitoad stops it with supersonic, making it confused. Palpitoad then laughs while Excadrill lets out focus blasts that hit Palpitoad. Palpitoad then uses another Hydro Pump causing more water and then mixes it with mud from a mud shot to cause a swampy-like field. Excadrill is massively hurt and looks around for Palpitoad who is hiding behind it in the swampy water. It emerges and finishes the mole off with one final hydro pump. Palpitoad wins and starts jumping, wanting more while Iris is scared on what to do.
Palpitoad vs Zweillous-Zweillous lands double hit's and body slams then tries for a dragon pulse but Palpitoad deflects it with mud shot. Palpitoad then tries to make more swamp on the field and then manages to learn sludge wave. Zweillous is badly hurt and Palpitoad tries to finish with one last mud shot. Palpitoad wins but is reluctantly recalled.
Litwick vs Druddigon-Becoming more awake and focused, Litwick releases a couple of shadow balls, lowering Druddigon's special defense. Druddigon however uses hone claws and dragon pulse to hurt litwick and power up. Litwick is nearly down and then tries to get close to Druddigon, wanting to use overheat near it. Druddigon starts charging up draco meteor and the two attacks collide when Litwick is on top of Druddigon. Massive blast, both are down but Litwick is massively injured. Cilan takes it to the pokemon centre while Drayden insists the battle continues.
Cubchoo vs Mienfoo-Cubchoo realises that it is at a disadvantage but tries to go on, using moves such as icicle crash and shadow claw. Mienfoo though hurts it badly with jump kick and focus punch. Cubchoo tries for a icicle crash but cannot stand up. Ash decides to prepare Scrafty for a final battle.
Palpitoad vs Mienfoo-Mienfoo quickly tries to land some jump kicks but Palpitoad surrounds itself with sludge wave, poisoning Mienfoo who is engulfed in the wave. Palpitoad then finishes it off with a close hydro pump though wishes it had toyed around more with supersonic.
Palpitoad vs Haxorus-For the first time, Palpitoad feels intimidated though wants to battle more. Palpitoad goes for a mud shot that Haxorus deflects with Dragon Tail. Palpitoad tries Hydro Pump but Haxorus pushes most of the water away with X-Scissor. Palpitoad looks to Ash who is thinking and then orders a sludge wave. Palpitoad tries it which holds Haxorus down but then it starts Outrage. Palpitoad immediately tries to hold it down more with sluge waves but to no avail. Haxorus then gets in close to Palpitoad who tries another Hydro Pump but although it hits, its not enough. Palpitoad is out. Ash tells it they will work on attacks and synchorisation later.
Scrafty vs Haxorus-Interesting battle, Scrafty uses crunches and hi jump kicks which pushes Haxorus back while Haxorus uses Dragon Dance to power up. Scrafy smirks while using bulk up, then goes in for a focus punch which turns into ice punch. Haxorus is hurt badly but manages to escape before another ice punch. Haxorus lands an X-Scissor, badly hurting Scrafty who tries to defend with hi jump kick. They then smirk then use bulk up and dragon dance. They then knock each other out with Ice Punch-X-Scissor.
Drayden is impressed by Ash and tells Iris that her pokemon have grown strong but she has much to learn about herself and the pokemon world, saying she needs to be more focused. Iris tries to say that she is better than ash, demanding an immediate one on one with their starters. Ash agrees with Cilan telling Drayden to try and go easy as Iris is a bit angry. Drayden however notes that she will learn to focus.
Pikachu vs Excadrill-Excadrill has rested after the last battle and immediately uses drill run to shake Pikachu about who escapes with quick attack and then thunderbolts the ground, unleashes parts of it onto Excadrill, hurting it a bit. Pikachu then lands an iron tail to the hit while Excadrill tries to use focus blast around the field. Ash thinks strategically and has pikachu stand close on some ground where parts of it land on Excadrill again. Pikachu does another iron tail and Excadrill falls while trying to hit Pikachu with a metal claw. Pikachu however, evades and stands tall, getting revenge on Excadrill.
Drayden tells Iris to go with him after she watches ash finish the unova league to learn how to be more devoted to battling. She agrees and then Ash sets a date for the 8th gym battle. I'll do that later.
I like you idea, but I want Leavanny to get at least one victory. And I think two wins are enough for Palpitoad. Those are my on critiques. Aside for those things, that sounds like a great idea.
