Nils, Tana, Ren and Firenze were walking to the Celadon Gym for Nils' Gym Battle and Nils was psyched.

"So Tana," asked Firenze, "What's the Gym Leader like?"

"Well," said Tana, "I learned that the Gym Leader lived in a jungle with his parents when he was little and went on some interesting adventures at the time." "For some reason during his time in the jungle he was only able to bond with Grass Type Pokemon." "Some time after his family moved to Celadon City, he gained a reputation as a strong trainer that only used Grass Types and caught the attention of the former Gym Leader who also used Grass Types. "After a battle between the two, the former Gym Leader passed the title to the new Gym Leader and left to travel the world selling perfume."

"That's an interesting story," said Firenze as the four of them arrived at the Gym.

Once the four of them entered the Gym, they were greeted by a man that seemed to be slightly older than Firenze, had long, messy, brown hair and was wearing a green sweater and brown pants.

"Welcome back Tana," said the man, "I'm guessing one of these people came here to challenge and you decided to watch?"

"That's right," said Nils who stepped forward, "My name is Nils and I challenge you to a battle."

"Very good," said the Gym Leader, "Let's get started." "By the way, I'm George and I know how to use Grass Types."

Later, everyone got to the battlefield and George and Nils got to either side while everyone else went to the stand.

"The Gym Battle between George, the Gym Leader, and Nils, the challenger, will now begin," said a female referee with long, curly hair. "Each trainer will use three Pokemon and the winner will be decided if the other trainer's Pokemon are all unable to battle." "Now begin."

"Go Sunflora," said George who sent out his Sunflora.

"Go Ivysaur," said Nils as he sent out Ivysaur. "Use Sludge Bomb," and Ivysaur launched Sludge Bomb at Sunflora which caused super effective damage.

"Use Sunny Day," said George and Sunflora made the area all sunny.

"Use Tackle," said Nils and Ivysaur used the move of choice which was a direct hit.

"Use Solarbeam," said George who was smirking and Sunflora attacked Ivysaur up close with the move that was chosen.

"Hold on," said Ren, "I thought Solarbeam had to charge for a while in order to work."

"Normally that's true," said Tana, "But when there's powerful sunlight, Solarbeam launches right away" "Also, Sunflora's ability is Solar Power which increases special attack in sunlight." "I learned all of that the hard way."

"Use Sludge Bomb," said Nils and Ivysaur launched the move but Sunflora dodged.

"Use Mega Drain," said George and Sunflora hit Ivysaur with the move and was partially healed.

"Use Sludge Bomb again," said Nils and Ivysaur tried Sludge Bomb again which not only hit Sunflora but also poisoned it.

"I think I have to do this," said George, "Use Solarbeam," and Sunflora hit Ivysaur with the move of choice but then took damage from the poison.

"Use Tackle," said Nils and Ivysaur used the selected move which knocked out Sunflora.

"Sunflora is unable to battle, Ivysaur wins," said the referee.

"Nice job Sunflora," said George as he returned his Sunflora, "Go Breloom," and a Breloom was sent out.

"Ivysaur return," said Nils who knew Ivysaur took a lot of damage from battling Sunflora, "Go Machop," and Machop came out, "Use Karate Chop," and Machop used the move of choice which hit Breloom.

"Use Leech Seed." said George and Breloom landed the move of choice on Machop who then had his energy sucked from him and into Breloom. "Use Force Palm," and Breloom charged at Machop while using the chosen attack.

"Use Revenge," said Nils and once Breloom's Force Palm landed, Machop attacked back with revenge which did a lot of damage. "Keep it up with Strength," and Machop managed to hit Breloom with the chosen attack which knocked it out.

"Breloom is unable to battle," said the referee, "Machop wins,"

"You did what you could Breloom now take a rest," said George as he returned Breloom. "Now for my best, go Tangrowth," and a Tangrowth appeared on the battlefield.

"Use Low Kick," said Nils and Machop landed the attack.

"Use Vine Whip," and Tangrowth attacked Machop with the chosen move which knocked out Machop because he was weakened by Leech Seed.

"Machop is Unable to battle," said the referee, "Tangrowth wins."

"Let me tell you something interesting," said George as Nils returned Machop, "The main role for Sunflora and Breloom is to severely weaken challenger's Pokemon while Tangrowth finishes them off with his great power."

"Go Ivysaur," said Nils who was hoping to try the same thing. "Use Sludge Bomb," and Ivysaur landed the attack on Tangrowth who got poisoned.

"Use Bind," said George and Tangrowth used the selected move on Ivysaur.

"Use Sludge Bomb again," said Nils and Ivysaur managed to hit Tangrowth with another Sludge Bomb while taking damage from the Bind.

Eventually Ivysaur took so much damage from Bind, she was knocked out.

"Ivysaur is unable to battle," said the referee, Tangrowth wins."

"Return Ivysaur," said Nils who knew he had one shot at this, "Go Ledyba," and Ledyba came out with a brave look. "Use Silverwind," and Ledyba hit Tangrowth with the move which raised all of his stats.

"Use Ancient Power," said George and Tangrowth hit Ledyba with the selected move which gave Ledyba lots of damage and then raised all of Tangrowth's stats.

"Hang in there Ledyba," said Nils who became worried.

Just then, Ledyba went back into the air and evolved into Ledian which gave Nils hope.

"Ok then," said Nild, "Use Aerial Ace," and Ledian used the move of choice which did lots of damage to Tangrowth. "Use Silverwind," and Ledian used the chosen move which became really powerful due to Ledian's ability, Swarm. "Now for your new move, Double Edge," and Ledian used his new move.

"Use Vine Whip," said George but Tangrowth had taken so much damage, it was unable to use the chosen move in time and was knocked out once it got hit by Double Edge..

"Tangrowth is unable to battle," said the referee, "Ledian wins which means the winner of this Gym Battle is Nils."

"I did it," said Nils, "I was worried for a few minutes but I did it."

"Indeed you did," said George as he returned his Tangrowth, "And for beating me, you have earned the Rainbow Badge." and George then walked over and gave Nils the Gym Badge.

"That was so awesome Nils," said Tana who then walked over and kissed Nils on the lips.

"Now you have three badges Nils," said Firenze who also walked over along with Ren.

After saying goodbye to George, Nils, Tana, Ren and Firenze left the Gym and went back to the Pokemon Center so Nils could heal his Pokemon.

"So I'm guessing we'll now go to the Unova Festival," said Ren after Nils gave his Pokemon to Nurse Joy.

"Yup," said Tana," The festival is two days away and it will take one day for us to get there."

After Nils got back his fully healed Pokemon, he, Tana, Ren and Firenze left Celadon City and went for the Unova Festival in Darto Town.
