In fanfiction, there could be multiple ways for Goku to control Baby GT to obey. One way could be that Goku has trained in a new form of martial arts that not only gives him physical strength but also mental dominance. He could use this new skill to break into Baby GT's mind and assert his will. Additionally, if there are some sort of magical or otherworldly elements in the fanfiction, Goku might get help from a wise being. This being could teach Goku a special incantation or give him an item that enables him to control Baby GT. For example, a magical amulet that when activated, allows Goku to manipulate Baby GT's actions and thoughts.
Well, perhaps in the fanfiction, Goku discovers a way to tap into a spiritual connection with Baby GT. Since Goku has a pure heart and strong spiritual energy, he could use this to his advantage. By establishing a link, he can send commands directly to Baby GT's mind, just like how some telepathic abilities work in the Dragon Ball universe. Another possibility is that Goku finds an ancient relic or spell that grants him the power to control Baby GT's actions.
One possible scenario is that Goku does it to stop Baby GT from causing destruction. He realizes that the only way to prevent chaos is to control Baby GT's actions, so he uses his new - found mind - control ability. Another scenario could be that Goku is forced to do it by an even greater threat. Maybe an enemy is using Baby GT as a weapon, and Goku has to take control to turn the situation around.
In fanfiction, Goku's brain control of Baby GT can have a huge impact on the story. It could lead to unexpected plot twists. For example, Goku might use this control to turn Baby GT's power towards good instead of evil. This would completely change the power dynamics in the story and the relationships between characters.
Baby Goku in GT fanfiction is significant because he allows writers to explore uncharted territories of the GT universe. His character can be used to create new plot twists and turns.
Baby Goku in GT fanfiction can be a really interesting concept. A lot of times, authors will play with his Saiyan nature more. They might show him struggling with the dark side of his Saiyan instincts, which was somewhat present in the GT series but can be expanded upon in fanfiction. This could lead to some really cool character development and new story directions.
Goku may want to reform Baby GT. By having brain control, he could influence Baby GT's thoughts and actions, guiding him towards a more positive path. This could be part of Goku's overall desire to protect the universe and make it a better place.
Don't forget about the power levels. In a crossover fanfiction, it's important to balance the powers. If Goku is in a world with less powerful characters, don't make him overpowered to the point where there's no challenge. Instead, find ways for him to be restricted, like maybe the new world has a different type of energy that he has to learn to control before using his full power. This way, the story remains interesting and the other characters can still play important roles.
One possible fanfiction could be Gt Goku traveling back in time to prevent the destruction of Earth in an earlier timeline. He could use his knowledge from the GT era to stop a powerful enemy that was previously victorious.
Another option is a crossover with a different anime world, like Naruto. GT Goku could end up in the Hidden Leaf Village. The shinobi would be amazed by his power. Goku, being Goku, would be interested in learning their ninja techniques. They could team up against a common enemy that somehow has the ability to use both chakra and ki, creating a unique and exciting battle scenario.
To develop Goku Jr's character further, he could be given more complex emotions. For example, showing his fear in the face of truly overwhelming enemies, rather than always being fearless like Goku. This would make him more relatable. Also, exploring his relationships in more depth, like his friendship with Pan. Maybe they have a falling out over different views on how to protect their world, which forces Goku Jr. to grow and understand different perspectives.
By showing Gine as a protective figure in Baby Goku's life. For example, she could save him from a minor danger, like a small wild animal attack. This would make Baby Goku look up to her more and strengthen their relationship.
