First of all; I do not own any characters, places, creatures, or organizations that appear in this story. Also, I do not take credit for any real life people, places or shows that may appear within the story. The only thing in this story that I do take credit for is the storyline. This is my second fanfic ever and I would really like as much feedback as possible. Please review.
Onix and Pikachu stare each other down, both growling softly. Ash stands cringing as he views the scene of the colossal rock snake Onix towering over his electric mouse Pikachu. Brock stands with his arms crossed in front of his chest, a look of determination and confidence is on his face.
"Ok Ash," Ash looks at Brock as the Pewter City gym leader begins to speak. "I think it is time to show you what it really means to battle an official gym leader. Onix, use Rock Throw! Give to everything you got!" Onix lets out a loud roar and slams its tail into the ground, forcing up a bunch of huge rocks and bouncing Pikachu into the air as well. "Let's see you dodge it this time." Onix slams his tail into the rocks and sends them flying towards Pikachu, who is still off the ground.
"Pikachu, use Quick Attack and get closer to Onix!" Ash yells. Pikachu launches itself forward and grabs one of the rocks. It runs to the other side of the rock and launches towards another. It continues to bounce from rock to rock until it reaches the final rock. "Now, use Quick Attack and aim for Onix's face!" Pikachu lets out a loud squeal and charges at Onix. Before the electric mouse can get within striking distance, Onix slams its tail into Pikachu. Pikachu flies through the wall and lands outside.
"Nice try Ash, but you are going to have to do better than that!" Brock smirks. Onix roars and starts to move outside. Ash and Brock follow the battle outside and arrive just in time to see Pikachu stand up. Pikachu is a bit shaken up and is very wobbly on its feet. "I'm surprised that your Pikachu can still stand. Obviously it has a strong will. But will alone can't win a battle." Onix roars again. "Alright Onix, let's wrap this one up. Rock Throw once more.
Onix slams its tail into the ground and a plethora of rocks leap out of the ground. Pikachu growls softly. "Pikachu, give it everything you got! Thunderbolt, full power!" Pikachu's body begins to spark as Onix slams the rocks forward. Pikachu lets out a loud squeal and releases a huge steam of electricity towards Onix. The attack cracks the rocks in half and collides with Onix. It knocks the colossal rock Pokémon down onto its side.
Brock stands in shock, "What? How is it possible for a Pikachu to have so much power?"
On the top of the Pewter City museum, three figures watch the battle on fold with great interest. "I knew that Pikachu was no ordinary little pipsqueak."
"You were right, with power like that it could rival even the Pokémon of legends."
"Maybe we should turn our attention to acquiring it, after we are finished here of course." The trio turns their attention towards the air vent on the museum roof.
Onix slowly uses its tail to prop itself back up. It shakes itself off and roars at Pikachu. "That was unexpected, but I won't make the same mistake again!" Brock points at Onix. "Time to step it up a notch Onix, use Dig!" The rock snake dives into the ground and disappears.
Pikachu looks around frantically, confused about what has just occurred. Ash growls and tries to think of what he should do now. 'We were already fighting an uphill battle but now Onix has disappeared underground.' Ash looks at the other two Pokeballs on his belt. 'I could call Pikachu back and let Butterfree or Pidgetto handle things from here.' Ash looks as his battered Pikachu. 'Alright, I'll turn things over to Butterfree for now.' Ash nods his head. "Pikachu, come here!" Pikachu looks at Ash and starts to run toward him.
"Sorry Ash, but Pikachu could be a threat later on in the battle. Onix, cut off Pikachu's escape!" Onix emerges from underground right in front of Pikachu. "Now use Slam!" Onix thrusts its body right at Pikachu.
"Get out of there Pikachu!" Pikachu dives to the right, barely dodging the attack. "Now hurry before Onix has time to recover!" Pikachu dashes towards Ash as Onix gets up. Ash grabs a Pokeball and hurls it into the air. "Alright, now let's go Butterfree!" The ball opens but Butterfree doesn't emerge, instead Pidgetto appears. "Oh no, I grabbed the wrong Pokeball!"
"Too late to try to take it back! Onix, use Wrap on Pidgetto." Onix thrusts its tail into the air to try to grab Pidgetto.
"Dodge it Pidgetto!" Pidgetto glares at Ash and flies towards him. It starts pecking at Ash's head. "Hey, stop that!" Ash yells. Pikachu quickly leaps up and grabs Pidgetto then uses Thundershock on it. Ash puts Pidgetto back into its Pokeball. "Guess I'll have to handle that later. But for now," He grabs Butterfree's Pokeball. "go Butterfree!" Butterfree emerges and flies high into the air.
"This could be trouble. Onix! Use Rock Throw then Dig. Onix slams its tail to raise rocks then sends them flying towards Butterfree who gracefully dodges, then dives underground. Butterfree hovers high above the ground, swaying from left to right. "Let's try something new. Onix, use Rock Throw from underground!" After a few seconds, rocks start to fly out from the ground. Butterfree flies around the rocks, managing to dodge each one. "Now, attack with Slam!" Onix bursts out of the ground and launches towards Butterfree.
"Now Butterfree, use Sleep Powder!" Butterfree starts spinning around and unleashes a tornado of blue powder showering down onto Onix. The colossal rock snake is covered in the powder and, just as it is about to reach Butterfree, it plummets to the ground. It crashes hard into the ground and causes a huge dust cloud.
As the dust clears, Onix is laying on the ground asleep as Butterfree slowly lowers itself to the ground next to Ash. "Hm, well that was an impressive move choice." Brock looks at Ash. "Hm, I'll have to concede this match to you Ash. Congratulations on winning your first gym battle."
