Well, perhaps in this fanfiction, Goku Black makes a fatal mistake. He could underestimate Goku's ability to adapt during battle. Goku, being the experienced fighter he is, notices this weakness and uses it against Goku Black. He might use a combination of his signature moves like the Kamehameha in a new and unexpected way that catches Goku Black off - guard, leading to his defeat.
Kid Buu is a very powerful and chaotic villain in Dragon Ball FighterZ. In the story, he is extremely destructive. He has a very simple and brutal nature, just wanting to cause chaos and destruction everywhere. His power level is off the charts, and he gives the Z - fighters a really tough time.
One key event is Kid Buu's destruction of many planets early on. Another is when Goku and Vegeta fuse to try and take on Kid Buu. Also, the moment when the Z - fighters come up with a final plan to defeat him is important.
The story could start with Goku being pushed to his limits by Goku Black's attacks. But then, he remembers his training with the Kai's and how they taught him to focus his energy in a more efficient way. He then uses this knowledge to create a more powerful Kamehameha that breaks through Goku Black's defenses and kills him.
The interesting aspects in 'Goku and Fem Buu Lemon Fanfiction' might include the exploration of their relationship in a new light. Goku is known for his friendship - based relationships, but with Fem Buu, it could be something more complex. It could be a relationship that starts off rocky but then evolves as they face challenges together. Another aspect could be the world - building. The fanfiction might create new settings or tweak the existing Dragon Ball universe. For instance, a new planet where Goku and Fem Buu are stranded and have to rely on each other to survive. This would not only test their abilities but also their relationship.
Often, Kid Goku is portrayed as the carefree and adventurous type. He's always looking for the next exciting thing to do, whether it's chasing after a strange animal or exploring a new area. He might be a bit naive in some aspects, especially when it comes to things like emotions.
The Naruto - Kid Buu fusion in fanfiction could be depicted as a being with a unique fashion sense. Since Naruto often wears orange and Kid Buu is mostly pink, the fused form might have a combination of those colors in its clothing or body markings. In terms of abilities, it could be shown as having the speed of Naruto when he uses his chakra to enhance his movement, combined with Kid Buu's ability to transform parts of his body into weapons. For example, the fused form could create Rasengan - like attacks from its hands which are also able to stretch like Kid Buu's arms.
In a fanfiction where Naruto fuses with Kid Buu, it could result in a very powerful and unpredictable being. Naruto's positive energy and strong will might conflict with Kid Buu's chaotic and destructive nature at first. But perhaps over time, Naruto could influence the fused form to use its power for good. For example, the fused being might have Naruto's skills like the Rasengan combined with Kid Buu's ability to regenerate and his raw power. It could also lead to some really interesting battles against other powerful characters in the Naruto and Dragon Ball universes combined.
One idea could be a crossover with the Dragon Ball Super universe. Kid Buu could encounter new and powerful foes like Jiren. Their fight would be chaotic and destructive, with Kid Buu's unpredictable nature causing all sorts of mayhem. Another idea is a crossover with the Naruto universe. Picture Kid Buu facing off against Naruto. Naruto's positive energy and willpower could be a contrast to Kid Buu's pure evil. He might try to reason with Kid Buu at first, but when that fails, a huge battle would ensue. And a third idea could be a crossover with the One Piece world. Kid Buu might land on the Grand Line and start causing trouble for the Straw Hat Pirates. Luffy would surely step up to protect his crew and the islands they visit from Kid Buu's rampage.
