Powerpuff! (Powerpuff Girls x reader)

History lesson

Ben Tennyson was just 10 years old when he first discovered the Omnitrix, a powerful alien device that allowed him to transform into various alien species. While on a summer road trip with his Grandpa Max and cousin Gwen, Ben stumbled upon the Omnitrix after it crash-landed on Earth.

Although he started out as a brash, somewhat immature kid, Ben grew through the many battles he faced against enemies like Vilgax, the Forever Knights, and Zombozo. He learned the importance of heroism, responsibility, and teamwork.

As Ben got older, he continued his journey as a hero, gaining new forms and facing tougher foes. At 16, Ben used the Omnitrix more skillfully and tackled larger threats, such as the Highbreed invasion and the threat posed by Aggregor. He faced difficult moral decisions that further shaped his character.

During his teenage years, Ben became a well-known hero. While he initially let the fame get to his head, he gradually learned that heroism wasn't about recognition, but about helping others. His cousin Gwen and his friend Kevin Levin helped him stay grounded.

Julie Yamamoto was an athlete and scholar from a young age. Growing up, she was dedicated to sports, particularly tennis, where she excelled, often competing in local tournaments. She had a strong sense of discipline and focus, which helped her succeed in both her academic and athletic pursuits.

Her family instilled in her the values of kindness, patience, and perseverance. She always had a desire to help others, which drew her to volunteer work and community involvement throughout her school years.

Julie met Ben in high school when he was still adjusting to his role as a local celebrity hero. Despite his superhero status, Julie saw Ben as a regular guy, which Ben appreciated. She grounded him and reminded him of the importance of a normal life outside of hero work.

Julie's loyalty and understanding earned her a special place in Ben's life. She had no problem standing up to him when necessary, which helped him grow as a person. Although she wasn't a superhero herself, she adapted quickly to the chaotic lifestyle that came with being with Ben, even piloting the ship Ship, an alien symbiote that bonded with her, on several occasions to assist him in battles.

Julie pursued a degree in environmental science, driven by a passion for preserving Earth and making a positive impact. She continued to play tennis competitively and later became a coach, teaching younger players and promoting the importance of sportsmanship.

While Ben traveled the universe, Julie built a successful career as an environmental researcher and advocate, focusing on sustainable technology and eco-friendly practices. She often worked on projects that kept her close to nature, sometimes using her knowledge to assist Ben with environmental-related missions.

After years of battling alien threats, Ben and Julie decided they wanted a more stable life together. They were in their early twenties and had been through so much as a couple, facing countless challenges, both on and off the battlefield. Ben proposed to Julie on a quiet night under the stars—just the two of them, reminiscent of their first dates. She said yes without hesitation, and the two began planning a small, intimate ceremony with close friends and family.

The wedding took place at a serene outdoor venue, with Grandpa Max officiating. Gwen served as Julie's maid of honor, and Kevin was Ben's best man. The ceremony was beautiful, filled with moments of laughter and heartfelt words. Ben, never one to be overly serious, couldn't resist making a few jokes, but when he saw Julie walking down the aisle, his usual bravado melted away. As they exchanged vows, he promised to be not only her hero but also her partner in life's quiet moments.

After the wedding, Ben and Julie honeymooned in Japan, where they spent time with Julie's relatives, explored her heritage, and created memories that they would cherish forever.

Julie, who had spent summers visiting her family in Japan, had always wanted to show Ben some of her favorite places. They spent their first few days in Kyoto, staying in a traditional ryokan (Japanese inn) surrounded by lush gardens and beautiful cherry blossoms.

They visited ancient temples, like Kinkaku-ji (the Golden Pavilion) and Fushimi Inari Shrine, where they walked hand-in-hand through rows of vermilion torii gates. Julie explained the significance of each place, and Ben listened intently.

Of course, Ben's adventurous spirit needed a bit more action, so they planned a hike up Mount Fuji. They woke up before dawn, joining a group of climbers as they trekked up the mountain. The climb was challenging, but Julie's encouragement kept Ben motivated. When they reached the top, they watched the sunrise together, standing side by side as they looked out over the breathtaking view.

Afterward, they spent a couple of days in Okinawa, where they swam in crystal-clear waters, explored hidden coves, and enjoyed time snorkeling. Ben marveled at the colorful marine life, comparing it to some of the alien worlds he'd encountered. For Julie, these moments with Ben were a perfect balance of excitement and romance, reminding her that every moment with him felt like an adventure.

As food lovers, they dove into the local cuisine, sampling everything from ramen in a cozy street-side shop to fresh sushi at the famous Tsukiji Fish Market. Julie introduced Ben to traditional dishes, such as okonomiyaki (savory pancakes) and takoyaki (octopus balls). They took a sushi-making class together, where Ben's enthusiasm led to a few clumsy moments, but Julie couldn't help but laugh, appreciating his eagerness to try something new.

They also attended a tea ceremony, where Ben was surprisingly attentive, carefully observing the rituals involved.

For the first time in years, Ben allowed himself to be truly at peace, but little did he know that one last battle still awaited him.

A few years into their marriage, Ben was called into action one last time. Vilgax had returned, more powerful than ever, and this time, he had an unexpected ally: an Evil Way Big, an enormous, mutated version of one of Ben's own alien forms. This formidable team set out to conquer Earth, planning to dominate humanity and reshape the planet to their twisted ideals.

With Earth facing imminent destruction, Ben knew he couldn't ignore the call. He activated the Omnitrix, suiting up with Gwen and Kevin by his side, determined to put an end to Vilgax's reign once and for all. Julie, ever supportive, wished him luck and reminded him that she'd be waiting, no matter how long it took. She helped coordinate support on the ground, using her connections and skills to ensure civilians were safe.

The battle was grueling and unlike anything Ben had ever faced. Evil Way Big's sheer size and strength, combined with Vilgax's relentless attacks, pushed him to his limits. Ben used every alien form he could access, from Humungousaur to Atomix, each transformation allowing him to counter different attacks. However, it was only when Ben shifted into Alien X—a form he rarely used due to its intense mental strain—that he gained the upper hand. With Alien X's reality-altering powers, Ben managed to weaken both Evil Way Big and Vilgax, finally delivering the decisive blow that ended their threat.

The victory was bittersweet. Ben knew this would be his last time wielding the Omnitrix in full force. The battle had taken a toll on him physically and emotionally, and nearly killed him, but it reinforced his desire to move on, knowing he had made Earth safe once again. He returned to Julie, who greeted him with open arms, and they looked forward to building a life free from the constant threat of danger.

Not long after the battle, Ben and Julie received joyous news: they were expecting a child. The couple was thrilled, and Ben was eager to welcome a new Tennyson to the world. They decided to name their son Y/N Max Yamamoto Tennyson, honoring Ben's beloved Grandpa Max and reflecting both sides of their family's heritage.

During Julie's pregnancy, Ben found himself growing more reflective, thinking about the legacy he wanted to pass on to his child. He imagined sharing stories of his past adventures, but more importantly, he wanted to teach Y/N to be compassionate, brave, and kind, with or without superpowers.

On the day of Y/N's birth, Ben was a nervous wreck. Julie, calm as always, reassured him, reminding him that this was just as important as any battle he'd ever faced. After hours of waiting, Y/N Max Yamamoto Tennyson was born—a healthy, beautiful baby with his mother's eyes and his father's curiosity. When Ben held Y/N for the first time, he knew that his greatest adventure had just begun, one filled with quiet moments of love and joy instead of battles and danger.
