Well I took a crack out of rewriting your plot summary.
Plot Summary:
In the serene town of Petra Vida, located in the Laxar region, a young protagonist lives a blissful and ordinary life for seventeen years. However, tragedy strikes when their mother passes away, leaving behind a shattered family. The protagonist's father, consumed by grief, becomes distant and neglectful towards his son or daughter. One fateful night, while the protagonist is asleep, their father, overwhelmed by anger, storms out of the house, driven by the belief that someone is responsible for his wife's death—the Tournament of Fighters or the formidable Elite Four.
Awakened by a knock at the door, the protagonist discovers the frantic town professor, who urgently inquires about their well-being. Unbeknownst to the professor, the protagonist feigns being fine, concealing their true emotional turmoil. The professor implores the protagonist to seek assistance at the Pokémon Lab and agrees to accompany them.
Inside the lab, as the professor ventures upstairs, the protagonist spots a box brimming with 24 Poké Balls, each containing one of the region's primary starter Pokémon, alongside a conveniently placed Pokédex on a nearby table. Seizing the opportunity, the protagonist succumbs to temptation, pocketing a starter Pokémon and the Pokédex before leaving the lab in hopes of catching up with their father. Unwittingly, they embark on an unexpected Pokémon journey, gradually collecting gym badges and encountering influential individuals.
Eventually, their journey leads them to the highly anticipated Tournament of Fighters. Along the way, they defeat four formidable Elite Fighters, only to face the reigning champion in a climactic showdown. Astonishingly, the champion turns out to be their father, who had supposedly eliminated the previous champion to claim the title, driven solely by the desire to reunite their broken family.
As the protagonist engages in a heartfelt battle with their father, emerging victorious, he reveals that all his actions were motivated by a thirst for revenge against those responsible for their mother's demise. However, fueled by resentment, the protagonist releases their remaining Pokémon, commanding them to wreak havoc. In order to preserve their reputation, the tournament organizers discreetly cover up the aftermath, allowing the protagonist to retain their Champion status due to the invaluable friendships forged along their journey.
With the tournament concluded, the protagonist returns to their hometown to seek forgiveness from the professor who aided them. Miraculously, the professor pardons their actions, acknowledging the protagonist's resilience in overcoming adversity. In gratitude, the professor shares a tale of a legendary island said to house both ancient and contemporary Pokémon, offering a glimmer of hope and new adventures on the horizon.
