Leaf

Leaf is a Pokemon Trainer, and a member of Team Bayleef at Professor Sycamore's Kalos Pokemon Summer Camp!

Pre-Pokemon Summer Camp
When she was younger, Leaf was forced into becoming a Masked Child, working for the Masked Man and his organisation. She - along with the other Masked Children - were tested on and trained specifically for the Masked Man's goals. Specifically, these goals related to Celebi, who the Masked Man eventually managed to get his hands on. After years of being a Masked Child, Leaf managed to escape the Masked Man, taking his prized possession -Celebi - along with her.

Leaf felt unprotected alone, and needed others to rely on. In desperation, Leaf broke into Professor Oak's Lab, and stole a Squirtle who was being prepared for brand-new Pokemon Trainers. She was relentessly chased by the Masked Man and his allies, for years to come. Meanwhile, she trained a team of Pokemon herself. At one point, Leaf and her Pokemon were surrounded by the Masked Man's organisation, and her Pokemon had no choice but to artificially strengthen themselves with chemicals and substances Leaf had taken from the Masked Man. As a result, they managed to escape, cutting it closer than ever.

Leaf then steamrolled the Kanto Gym Leaders and Pokemon League, using her strengthened Pokemon. She had the intent of doing this to publically show her strength, with the hopes of making the Masked Man scared of chasing her. However, she was quickly recognised by the police as the girl who broke into Professor Oak's Lab. Her victories were covered up by the police, and soon, she was being chased by the police, too.

Leaf, desperate to do anything to help her situation, decided to attend the Pokemon Summer Camp in Kalos. There, she hoped to do two things. Firstly, she hoped to start again - to be able to spend time with her Pokemon, without fears of being chased by the Masked Man or the police. And, secondly, she hoped to develop strong bonds with other people and Pokemon, so that - if the time ever came - she would have extra support and protection against the Masked Man.

Pokemon Summer Camp
When the Summer Camp began, Leaf found herself in a team with Seiya, Bonnie and Clemont. Her team of Pokemon were so powerful that they were unbeaten for the majority of battle events in the Pokemon Summer Camp. After learning about Ash being the Alola League Champion, she admitted to him that she won the Indigo League in the past. However, the power of her Pokemon combined with her developing friendship with Ash, caused Serena, Chloe and Clemont to begin investigating her, suspecting something was amiss.

Serena, Clemont and Chloe began to suspect that Leaf had stolen a Squirtle from Professor Oak, after researching old newspaper columns and comparing them to things they knew about Leaf. They confronted Leaf with their suspicions, and Leaf eventually admitted the whole truth to them about what she had been through. They understood her dark her past was, and promised they wouldn't report her.

For the days following, Leaf distanced herself from Serena, Clemont and Bonnie, because she struggled with the reality of people knowing her past. This caused tensions within Team Bayleef, but she eventually spoke to Serena again, and began accepting this new reality.

Throughout the Summer Camp, Leaf noticed a fellow Summer Camper - Osanna, of Team Performer - watching her, on various occasions. She occasionally voiced her concerns about this, but she tried her best to brush it off. She also found the Secret Base of Shamus, a Summer Camper who had been kicked out earlier in the month. They began to bond over training, and she even showed him her Celebi, since she knew his secret - that he was sneakily remaining nearby the Summer Camp - and so he should know her secret, too.

In the Final Battle Tournament, Leaf made her way to the Semi-Finals, where she defeated Brendan's team, which included his Latios. Then, in the Finals, she faced Ash Ketchum. The battle was neck-and-neck, until it came down to just Pikachu VS Celebi. Leaf began to realise that Ash was going to win, but she was so afraid that her losing would make her seem weak, and so it could invite The Masked Man to begin chasing her again. So in that moment, the only thing she could think to do was use Perish Song, with the hopes of turning the battle into a tie.

Pikachu used the 10,000,000 Volt Thunderbolt Z-Move, which clashed with Celebi's Solar Blade. In the explosion that followed, both Pikachu and Celebi managed to stand up, before they were both knocked out simultaneously by the Perish Song that Leaf set up earlier. As a result, the battle was a tie, but because Team Bayleef had 1 more point than Team Greninja prior to the Final Battle Tournament, Team Bayleef were officially the winners of the Pokemon Summer Camp.

After this battle, Leaf faced some disapproval for her tactics from some Summer Campers, and she also faced many questions about her Celebi and her past. She began feeling overwhelmed, so she stumbled away, needing air. At this moment, when she was at her most vulnerable, she began hearing false voices in her head - voices of her fellow Summer Campers - being hateful towards her. She heard a strange ringing sound as she began to fall out of consciousness, and then, as she closed her eyes, she heard the voice of Osanna, saying 'Leaf'.

Leaf was later seen by Bonnie in the forest near the Pokemon Summer Camp, walking in a trance - as if she was possessed - and being led deeper into the forest by Osanna. Osanna then caught Bonnie too, and began leading her and Leaf away, both of them in a trance. They eventually woke up in an unknown cavern of caves, where Leaf came to the brutal realisation that Osanna was sent by The Masked Man, and was presumably one of his Masked Children. Leaf and Bonnie tried to escape several times, but Osanna effortlessly prevented this.

Leaf and Bonnie were eventually rescued by the other Summer Campers, including Ash - who used his awakened Aura powers to battle Osanna - and Shamus, who managed to tackle Osanna at the last second to save them all. When she came to terms with Osanna's identity as a Masked Child, she demanded Shamus to pull Osanna's 'mask' from her face, to reveal who she truly was. Shamus did this, but in that moment, a burst of energy exploded, and Osanna fled into a tunnel, carrying the Poke Ball that held Leaf Celebi's. Leaf was distraught, but thankfully, Ash's Greninja leapt into action, and managed to take Celebi's Poke Ball from Osanna, albeit with Osanna escaping.

Hours later, after returning to the Pokemon Summer Camp, Leaf made the entire group lie about what happened - she pretended that they were exploring a cave, and it caved in, leading to them being injured. Professor Sycamore believed this, but scolded them for being irresponsible. Leaf then persuaded Sycamore that Shamus helped them escape, and that it was just a coincidence that he was in the area after being kicked out earlier in the Summer Camp. Leaf also spoke to Diantha - the Kalos Champion - and asked her to consider battling Shamus at the Awards Ceremony, since he helped them out, and since she knew he really wanted to battle her.

Leaf also had a discussion with Ash, where Ash confessed that their battle in the final event left him dissatisfied and confused - since Leaf's method of ending the battle with Perish Song wasn't sportmanslike, and ended a great battle on a sour note. Leaf made Ash understand that not everyone has the liberty of battling for fun, or for a hobby, like Ash does. For her, battling is a method of survival - a way for her to be protected from those who seek to hurt her. So using Perish Song didn't feel wrong at the time - it felt like the only option to keep her safe. Ash understood this. Leaf then admitted that she learned a few things about Aura from The Masked Man, and that she thinks it was a mixture of the inner conflict Ash felt about his battle with Leaf, and the emotional conflict Ash felt about Leaf and Bonnie being kidnapped, that reawakened his Aura, and gave him more control over it. Ash and Leaf swore to each other that they'd battle again in the future.

That night, Leaf met up with Shamus in the forest nearby, and they discussed the day's events. As Leaf walked away, Shamus asked her why she bothered to be around him, when nobody else wanted to. She told him it's because he reminds her of an old friend - Silver. And with that, Leaf decided to leave the Summer Camp behind, because she didn't want to put her new friends at any more risk, since The Masked Man would inevitably continue hunting her down. She blocked everyone's phone numbers so that they couldn't track her, and then walked away from the Summer Camp with her Pokemon, leaving once and for all.

Pokemon
Celebi - Leaf's Celebi was captured by the Masked Man, for unknown reasons. Leaf managed to free it from being experimented on, and Celebi - in return - helped Leaf escape the Masked Man. Now, Celebi is Leaf's secret, who she only reveals to a tiny minority of people, if she feels she can trust them.

Celebi's current known moves are Ancient Power, Solar Blade, Recover, and Perish Song. Blastoise (Mega) - Leaf's Blastoise was originally a Squirtle, being prepared for a brand-new Pokemon Trainer and Professor Oak's Lab. However, Leaf broke into the Lab, and took him for herself, in an attempt to protect herself from the Masked Man. Blastoise was artificially strengthened by the Masked Man's chemicals, in an attempt to protect Leaf. This greatly increased his Defense, turning him into a 'living tank'. At some point in time, Leaf and Blastoise mastered Mega Evolution.

Blastoise's current known moves are Hydro Pump, Ice Beam, Iron Defense, and Skull Bash.

Ninetales - Ninetales is one of Leaf's Pokemon. She's incredibly protective over Leaf, and will attack anyone who puts her in danger. Ninetales was granted some Psychic-abilities from absorbing The Masked Man's chemicals.

Clefable - Leaf's Clefable was notable in the fact that it was immune to many different types of moves, for example, Latios' Luster Purge. This was a result of Leaf drenching her pokemon in chemicals while attempting to flee from the Masked Man. Clefable was very determined and powerful, and was only defeated by Ash's Charizard in the finals of the Pokemon Summer Camp
