One common theme is redemption. Since Zack has a tragic backstory in the original game, in crossovers he might be given a chance to redeem himself or find a new purpose. For example, if he crosses over into a world full of corruption, he could be the one to bring change. Another theme is friendship. Meeting new characters means new friendships, and these are often explored deeply in the fanfictions.
Fair tail fanfiction is fan - created stories based on the 'Fairy Tail' series. It can involve new adventures of the beloved characters, different pairings of the characters in romantic or platonic relationships, or exploring what - if scenarios in the Fairy Tail universe.
Sure. One popular Zack Fair crossover fanfiction might be the ones where he crosses over with characters from other Final Fantasy games. For example, a crossover with Cloud in an alternate universe setting. The stories often explore different relationships and adventures that Zack could have had if he interacted with different characters from the broader Final Fantasy universe.
Maybe Zack Fair could find himself in the wizarding world of Harry Potter. He might use his combat skills from Final Fantasy to fight against dark wizards. Or perhaps he could be a transfer student at Hogwarts, learning magic spells while also showing off his sword - fighting abilities.
It's a fictional concept. Harry Potter and Zack Fair are from different fictional universes. Harry Potter belongs to J.K. Rowling's wizarding world, while Zack Fair is from the Final Fantasy series. Combining them in a fanfiction is a creative and fictional idea created by fans who like to mash up different fictional elements.
It adds more content. The official Fairy Tail series has a limited number of episodes and chapters. Fanfiction fills in the gaps. For example, it can create stories about what the characters were doing during the time - jumps in the original story.
If Lucy never joined Fairy Tail, the friendships and relationships among the characters would form in a very different way. Also, many of the story arcs might not unfold as they do in the original plot.
