About time I place my challenge here!

"Hello! Anyone here I'm here to have a gym battle against Brock!" yelled Bom.

Brock saw Bom and grinned at him.
'Have you come to challenge me to a battle?' he asked.

"Yes, I have, may we begin the battle?" he asked.

'Yeah, go Sudowoodo!' shouted Brock as his first Pokemon came out. 'What are you gonna send out?'

"Hm, Pidgey won't do good here, nor will Chimchar nor Charmeleon.." he thought.
"Ok, so that means, go Manaphy!" Bom said.
"You can have the first move, Brock." said Bom.

'Okay, Sudowoodo! Rock Throw, let's go!' shouted Brock and Manaphy was pelted with a dozen medium-size rocks.
PS Can you tell me what levels your Pokemon are so I can calculate HP and things like that.

Err, Manaphy is level 14 and its HP is about 102.

"Manaphy, don't dodge, use a simple Surf," he said.
Manaphy followed accordingly, and that worked miraculously, the Rocks were thrown back at Sudowoodo by the power of the Surf and the itself caused calamitous damage to Sudowoodo.
Manaphy then jumped off the Surf with style showing off it's ribbon.

Sudowoodo
14/87 HP (Not 70, because it had to have leveled up with all those gym battles around the corner)

Manaphy
102/102 HP

'Sudowoodo, don't give up!' barked Brock. 'Use Wood Hammer!'
Sudowoodo did just that, but unfortunately on its follow through it hit itself.

Manaphy Lvl 14 83/102 HP

"That doesn't matter, does it, Manaphy?" he asked.
Manaphy grinned.
"Here's a special contest move I didn't really get the chance to use," he said. "Manaphy, use Recover!"
Manaphy recovered all it's HP and then used a Water Gun as Sudowoodo couldn't even move and Sudowoodo was finished off.
"Hey," Bom said grinningly. "good work Manaphy!"

Sudowoodo
0/87 HP

Manaphy
102/102 HP

'The battle isn't over yet, though,' Brock said challengingly. 'Go, Happiny!'

"I'll save Manaphy for later if I need it," Bom said. "For now, go Pidgey!"
"Use Gust on Happiny!" he said.
The Gust did a decent amount of damage.

Pidgey Level 5 HP 24/24
Happiny level 13 HP 69/93(You have to remember, Chansey and it's evolution line have the highest HP stat, so with those battles, it gained way more HP than the others!)

'This should be easy!' grinned Brock. 'Happiny, use Sweet Kiss!'
Unfortunately for Brock, his Pokemon became complacent and Pidgey was able to break away without kissing.

Pidgey Lvl 5 HP 24/24
Happiny Lvl 13 HP 69/93

"Yes," exclaimed Bom thinking of finishing Happiny in this turn. "now use the strongest Aerial Ace possible!"
Pidgey gathered up all it's power an released a magnificent Aerial Ace, which was a Critical Hit! And what Bom hoped for came true, he finished off Happiny! And looking at how Happiny gives a lot of exp when you beat it, Pidgey grew to level 16 in just one battle!
"Woohoo! We won! Pidgey, we won! Yay!" exclaimed Bom holding Pidgey in his hands.
"Ok, now just one more Pokemon to beat!" he added happily.

Pidgey level 16 HP 94/94

Happiny level 13 HP 0/93

'Happiny, return!' ordered Brock, trying to sound calm. He told Croagunk to battle and with a hoarse call of 'CROAGUNK!' it responded.

Croagunk Lvl 16 85/85 HP
Pidgey Lvl 16 94/94 HP

"Nice, this battle's gonna be.. interesting." said Bom.
"Pidgey, use Aerial Ace!" he added.
But unfortunately, Brock told Croagunk to counter with Poison Jab and both the Pokemon were hurt.

Croagunk level 16 57/85
Pidgey level 16 62/94

'Come on, Croagunk!' shouted Brock. 'Use Astonish!'
Croagunk obeyed and shocked Pidgey into flinching. Brock's Pokemon then used Mud Slap to reduce Pidgey's accuraccy.
Croagunk Lvl 16 57/85 HP
Pidgey Lvl 16 39/94 HP

Bom was struggling about what to do, he didn't want to change Pidgey as if he beat Brock with him, Pidgey would become very confident and would gain quite a few levels.
He suddenly remembered a tactic he once saw on TV and with his edited version, it was perfect.
"Pidgey, come back." said Bom, calling back Pidgey.
"Now, go, Pidgey!" said Bom looking really weird while throwing out Pidgey.
"Perfect, no more accuracy loss, is there?" said Bom.
"Now quickly, another Aerial Ace!" he added commanding Pidgey to use Aerial Ace.
It caused quite a lot of damage.

Croagunk
Level 16
14/85 HP

Pidgey
Level 16
39/94

Brock looked on, frustrated as Pidgey switched out and back in.
'Croagunk, use Pursuit!' the gym leader shouted.
Croagunk jumped into the air and Wham! knocked Pidgey flying! Bom's Pokemon reacted superbly as it managed to use its wings to avoid crashing onto the rocky ground below!

"Good job, Pidgey, come back." said Bom.
"Now go, Squirtle, finish off Pidgey's job with Bubblebeam." he added.
And Squirtle did, finish off Pidgey's job that is. Croagunk fainted.
"Yay, good job, Squirtle, and you too, Pidgey and Manaphy" he said holding Squirtle in his hands and looking at Manaphy and Pidgey's Pokeballs. But then suddenly, Pidgey's Pokeball started moving on itself it looked like when Pokeballs are catching Pokemon. Pidgey was then automatically sent out and then.. it started evolving! It evolved into Pidgeotto.
"Oh, yes, it still gained enough levels to evolve, that's great Pidgeotto," he said.
Pidgeotto replied by flying towards Bom's hand and sitting on it affectionately. And this just made Bom realize, when he caught Pidgey, it wasn't planning on biting Bom's hand off it was just trying to sit there and the way Bom was moving Pidgey would have be knocked off so it held itself by biting Bom's hand.
"Phew, at least this means you won't be biting me again." he said jokingly.
Pidgeotto just sat on Bom's hand relaxed. And it looked like Pidgeotto was on level 18 and Squirtle was on level 12.

'Bom, your Pokemon are pretty powerful,' said a shocked Brock. 'You've beaten me fair and square and therefore I present to you the Boulder Badge.'
Bom thanked the gym leader for his kind gift and placed the badge in his bag.
'Good luck in the future!' called Brock as Bom turned to leave.

"Thanks a lot, Brock," he said as he ran away out of the gym and shouting "Hurray! Hurray! I won my first badge," as soon as he got out.
"I actually got my first badge, woohoo! Thanks, Manaphy, Squirtle and Pidgeotto," he said to them as he had let out all his Pokemon.

Brock grinned to himself, murmuring 'At least I got beaten by someone who values the badge.'
