A/N: Here's The Rocky Gym Battle Experience chapter repost. Satoshi Tajiri owns Pokémon.

As Ash finally got out of Viridian Forest after much training, He arrives at Pewter City. He and Serena head inside the Pokémon Center and come across Gary sitting with Misty. "Hey Gary," he says as he rushes over and Serena follows him.

"I had a feeling you'd be here Ash," Gary said smiling. "I stayed put to give you a bit of advice."

"What kind?"

"Well the Gym leader here has Rock Pokémon so he's gonna be tough to beat."

"I caught a Dratini and her name is Claire so I shouldn't have too much difficulty right?"

"Well you may need more than just her and Serena. Plus Serena's Electric-type moves won't work on them since they're both partially Ground-Types as well." He pulls out a shiny gray box with the number 23 on it. "She should learn this. It contains Iron Tail. Misty had to learn it to beat the gym leader."

"Thanks Gary. How do I teach it to her?"

"Open it up over her head and some dust should fall out of it and have her learn it in place of a move you want to get rid of."

"Thanks again Gary." Gary then got up to leave giving a friendly wave to Ash as he left. Misty clung to Gary's arm as well. Ash shook his head knowing what was going on between those two. "Well Serena, should we give it a try?"

"If Gary says we should I think it's worth giving it a shot," she said calmly. Ash nodded as she got on one knee and Ash opened the box over her head. Sparkles of metallic grey fell on her body and seem to be absorbed into it. "I think it worked."

"Okay then let's practice it." They went outside and headed out towards a large boulder outside. "Serena, Iron Tail!"

"Right!" She jumped up and gained some good altitude. Her Pikachu tail glowed with a bright light and soon struck the boulder and shattered it to a thousand pieces. "Whoa it worked!" She rushed over and hugged Ash while giving him a deep kiss which he happily returned. They pulled away as they headed towards the Pewter Gym.

"Hello? We would like to try for our first gym badge please?"

"Hello," said a teenage voice. "You came to the right place." A teen a bit taller than Ash who had black hair and tan skin. His attire was an orange shirt under a green vest and green khakis. "I'm Brock, Leader of the Pewter Gym. Who might you be?"

"I'm Ash Ketchum of Pallet Town."

"So you're the other fabled special trainer sent out by Professor Oak."

"Well I wouldn't say 'special' but yes."

"What I mean is you have those special Pokémon that are in human form. A very rare mutation."

"Is there anything wrong with such a thing?" Serena asked a bit concerned about whether or not she had been turned into a freak.

"Not at all, young Pikachu maiden," Brock reassured her. "It's just a very rare privilege to be in such a situation." Serena sighed in relief. "But we're getting off topic. Since this is your first gym, I will use two Pokémon while you are allowed to use whatever Pokémon you have on you."

"Okay then this should be a good challenge," Ash said.

""I'll start with Geodude." Brock threw out his PokéBall and out came your standard Geodude. A ball of rock with arms, eyes and a large mouth.

"Claire it's time to shine!" Ash shouted as he threw her PokéBall. She popped out causing Brock to go gaga over her look.

"Whoa what a knockout!"

"In yours dreams perv!" Claire said as she fired a Dragon Pulse towards him. When he realized what was going on, he quickly dodged the move and regained his focus.

"S-Sorry, let's get on with it. Geodude Tackle!"

"Claire, dodge and use Surf!" Ash shouted. She jumped up and summoned water from around the air. Soon it flooded the entire battlefield and submerged Geodude underneath. As the water dispersed, Geodude was knocked out cold while Claire gave a pouty look of being unimpressed. "Can't say I blame you Claire. Go ahead and fall back. Bethany will take over."

"Right," she said as Ash pulled returned her to her PokéBall. Bethany was sent out next. Lately, it has shown that her training has come a long way. She was now a 5' anthro Butterfree with a blue dress over her purple body. Her eyes were now pink in color and her breasts grew quite a lot. They were now about a c-cup and her wings were also big enough to support her large body.

"Ready to go Bethany? It won't be easy."

"I'll give it my all," she replied pumping her blue fist.

"Brock, we're ready!"

"Onix, let's go!" Brock shouted as he threw his second PokéBall. This time a huge rock snake with a horn on its head came out. It was, yet again, your standard Onix.

"Bethany, Poison Powder!" Ash shouted. Bethany flew over Onix and purple dust falling on Onix.

"Onix Rock Tomb!"

"Oh shit." Ash knew Bethany was in trouble now. "Bethany, dodge until the attack is over!" The Butterfree girl dodged every one of the rocks and Ash quickly got her back in her PokéBall. "Serena, I need your assistance."

"Got it!" Serena ran out and got into a battle stance. She was scared but knew Ash was counting on her. Plus, since Bethany poisoned Onix, that made things a bit easier.

"Okay Serena, Iron Tail!" Serena jumped up at Ash's command and her tail glowed white again as it switched to a solid steel form. She then did a midair somersault like a trapeze artist, bringing her tail down on Onix's head. Onix groaned in pain as he felt the blow of Iron Tail. It was as if a wrecking ball hit him head on. He soon keeled over and he too had swirls in his eyes. Brock returned Onix and headed over to Ash.

"Well done Ash," he said as he approached him. "I admit I wasn't expecting your Butterfree to put up a good plan as you executed. It shows that you took your studies from Pokémon Elementary classes to heart back in Pallet."

"Well I couldn't have done it without my fiancé and her comrades," Ash replied as he held Serena.

"Hehe I take it you and this Pikachu are closer than I thought huh?"

"You don't know the half of it."

"Well in honor of your victory, I present you with the Boulder Badge." He got a pin out of his pocket that looked like an octagonal rock.

"YES! WE GOT THE BOULDER BADGE!" He shouted as he held it up in the air.

"WAY TO GO TO US!" Serena shouted after as Ash put it in his badge case.

"That is the first badge for the Indigo League. You have taken that first step into the big leagues so don't falter," Brock said.

"Right," Ash said as he put the badge case away "So where's the next gym?"

"The next one is in Cerulean City. Daisy is the Gym Leader there ever since her youngest sister disappeared."

"Oh okay. Well thank you."

"Have a safe journey."

"Bye." Ash soon left the gym with a quizzical look on his face. "The youngest sister went missing?"

"I wonder who it was," Serena said.

"Do you think it has anything to do with your mutation?"

"Possibly. We should ask who she was when we get there."

"Good idea. That will help a bit with Professor Oak's research on the subject." Serena nodded at Ash's comment as they headed towards the Mount Moon. The sun starts setting as the journey continues.
