I don't own Pokemon or the idea of this story which I got from Captain Buggles. I just own my OCs.
TMs will exist in this universe but instead of replacing older moves I will just add to the list like TM02 is still Razor Wind but Headbutt is TM57. I will put a list of TMs in this universe on my profile and I'll just make the HMs TMs as well.
Ash, Brock, Latias, May, and Max arrive at the Battle Pyramid.
The battle is set for a full battle. Brandon sends out Regirock. Ash sends out Buzzwole. Ash tells Buzzwole to use Brick Break. Regirock use Iron Defense to nullify the attack. Ash has Buzzwole then use Hammer Arm which hits and knocks Regirock down.
Max thinks Regirock is down and out, but the Rock Peak Pokémon stands back up and immediately uses Hyper Beam. Ash tells Buzzwole to use Protect which blocks the move. Ash tells Buzzwole to use Hammer Arm on Regirock's leg, causing it to kneel down. Regirock uses Lock-On, targeting Sceptile. Then Ash tells Buzzwole to use another Hammer Arm on the other leg, rendering Regirock immobile. Regirock uses Hyper Beam again. Buzzwole's attempt to dodge fails as Lock-On ensures that the attack hits. Hyper Beam comes around and Buzzwole is blasted to the ground but Buzzwole gets back up and defeated Regirock with a critical hit Focus Blast.
Brandon then sends out a Registeel. As Registeel is a Steel-type Brock says that any Fire, Ground or Fighting-type Pokémon would be a good choice. Ash returns Buzzwole and sends out Blacephalon. Max remarks how Ash has the type advantage and Scott says how Ash is playing it by the book. Ash telling Blacephalon to start with Flamethrower. The attack hits its mark and Brandon has his Registeel counter with Metal Claw. Ash tells Blacephalon to dodge and use Flame Charge which it does, knocking Registeel over. Ash compliments Blacephalon and Scott remarks how well Ash is doing. Brandon tells Registeel to use Zap Cannon and Ash counters with Fire Blast. The two attacks collide creating an explosion. Brandon has Registeel use Lock-On and then Zap Cannon and Ash tells Blacephalon to use Protect. Ash has Blacephalon use Flame Charge and Registeel tries to counter with Metal Claw and it hits.
Brandon compliments Ash on his strategy but says he is overconfident, and then orders Registeel to throw Blacephalon. It does so but Ash counters by having Blacephalon use the wall to re-direct another Flame Charge. Brandon says he is impressed but now wants Ash to throw everything at him. Ash tells Blacephalon to use Overheat. Brandon has Registeel break free from the attack and Ash has Blacephalon send another Flamethrower at it. Brandon tells Registeel to use Sandstorm which blocks the attack and traps Blacephalon in the vortex. Brandon has Registeel use another Sandstorm but Ash orders Blacephalon to counter with Psychic. Pushing the Sandstorm back, Blacephalon manages to trap Registeel. Registeel uses another Zap Cannon but Blacephalon dodges it and, under Ash's command, uses the power of the Sandstorm to strengthen its Flame Charge. The attack hits but Registeel holds on and Blacephalon strikes the legendary Iron Pokemon with Mind Blown which defeats Registeel.
Brandon calls upon his devious Dusclops while Ash returns Blacephalon and sends out Celesteela. Celesteela doesn't hesitate to being the battle with her Flamethrower as Dusclops counterattacks with Will-O-Wisp with both attacks clashing and dispersing into the atmosphere. Celesteela uses Brutal Swing as Dusclops uses Shadow Punch making for a direct hit. Celesteela recovers and strikes down with Energy Ball. After Dusclops manages to recover, he counterattacks with Mean Look. Celesteela charges again and descends towards Dusclops for a Fly attack, which hits directly. Dusclops takes advantage of Celesteela being up close and uses Confuse Ray to confuse Celesteela, which works perfectly. Dusclops strikes Celesteela with another Shadow Punch, sending it flying back into a wall as Ash tries to help Celesteela recover. Dusclops strikes down with Shadow Ball for a direct hit. Celesteela snaps out of confusion and launches Air Slash for a direct hit. Dusclops launches another Shadow Ball attack knocking Celesteela backwards. Celesteela is now pretty tired after all the damage taken, and Dusclops is also showing signs of fatigue. Celesteela charges forward with Heavy Slam, hitting directly and defeating Dusclops.
Brandon summons Ninjask, and Ash swaps for Naganadel. Ninjask uses Aerial Ace, but Naganadel uses Protect. Ninjask uses Sandstorm to blind Naganadel before using Double Team to surround it. Naganadel fires Air Slash at all of them, revealing Ninjask. Ninjask dodges Air Slash and strikes with Aerial Ace. Ninjask uses Sandstorm, but Naganadel s Dragon Pulse neutralizes it. Ninjask then uses Sand-Attack to blind Naganadel. Ninjask uses another Aerial Ace, but Naganadel can't see in order to block. Ash tells Naganadel to listen for it. Naganadel uses Protect, Ninjask executes another Aerial Ace, Naganadel manages to counter it with Sky Attack and knock out Ninjask.
Brandon sends out Solrock so Ash returns Naganadel and sends out Xurkitree. Xurkitree uses Thunder which hits. Then Xurkitree then strikes Solrock with Brutal Swing followed Power Whip and Energy Ball which knocks out Solrock.
Ash sends Nihilego out, and Brandon calls upon Regice. Nihilego fires a Thunderbolt, which Regice endures easily. Regice uses Blizzard, which Nihilego takes. Nihilego attacks with Iron Head, with Regice countering with Ice Beam. Nhilego dodges, but the attack freezes one half of the field and negates the attack. Nihilego uses Brutal Swing, but Regice negates it with another Ice Beam, which freezes the other half of the field. With the field covered in ice, Regice can move quicker. Regice attempts to use Focus Punch, but Nihilego uses Thunderbolt to paralyze Regice, and then strikes the Iceberg Pokémon with Iron Head. Regice uses Ice Beam to freeze the stadium more, creating a tomb of ice pillars that trap Nihilego.
With Nihilego immobilized, Regice uses Rest. Nihilego uses Iron Head to free herself. Nihilego races towards Regice, but it wakes up and fires Ice Beam, this time making a direct hit and freezing Nihilego in an ice pillar. Ash orders Thunderbolt, but Nihilego seems unable to. The referee begins to declare Nihilego unable to battle, but Nihilego uses Thunderbolt to shatter the ice and paralyze Regice again. Regice fires another Focus Punch to send Nihilego bouncing across the ice field. Ash manages to get Nihilego to use two Iron Heads in a row due to the ice. Regice uses Ice Beam to trap Nihilego in another icy tomb before using Rest again. Nihilego frees herself with Iron Head and starts charging forward with Head Smash. Regice wakes up and uses Ice Beam to try to freeze him again, but Nihilego dodges and hits Regice before it can launch another attack, knocking it out. Ash wins the match.
Brandon gives Ash the Brave Symbol, completing Ash's Battle Frontier quest. Scott hands Ash a plaque with all seven Symbols on it, acknowledging his position in the Hall of Fame, and offers Ash a Frontier Brain position. Ash declines, stating that he wants to travel more, but Scott tells him that should he change his mind, the offer will always be open to him. Brandon and the pyramid takes off.
Ash and May tie at an unofficial contest in Terra Cotta Town. Ash then defeats Gary's new Electivire with Rhydon using Fissure. Gary then gave Ash a Protector for Rhydon to hold and evolve when traded and Ash evolves Rhydon into Rhyperior.
