In a crossover with the Avengers, Iron Man could be an ally. His high - tech gadgets combined with Gohan's power would be a great team. Also in the Pokémon world, Ash could be an ally. Ash's knowledge of Pokémon and Gohan's combat skills could be useful. In the Bleach universe, Ichigo could be a strong ally for Gohan, with their combined sword - fighting and energy - blasting abilities.
There might be a fanfiction where Gohan and Towa form an unlikely alliance against a greater evil. In this story, Gohan could be learning some unique techniques from Towa, which would be really cool to read about as it combines their different powers and knowledge.
The love between Gohan and Videl in fanfiction also reflects the broader themes of growth and family in Dragon Ball Z. As they fall in love, they are also growing as individuals. Their relationship can be seen as a new chapter in the story of the Z - fighters. It adds a layer of warmth and humanity to the action - packed world of Dragon Ball Z, showing that even the mightiest warriors can have tender and loving relationships.
Future Gohan's character development would likely involve him becoming more resolute and determined. After all the hardships he's faced, he would grow stronger both physically and mentally. He might start as a somewhat broken hero, but as the story progresses, he'd regain his confidence and find new purpose in protecting what's left of his world.
