Another possibility is that his time travel could cause unforeseen consequences. It might disrupt the timeline in ways he didn't anticipate. For instance, changing a small event in the past could lead to a completely different set of Mavericks emerging, or it could even affect the relationships he has with other characters like Zero. His time travel journey would be full of risks and opportunities for self - discovery.
He could also gain a new perspective on his own development. By seeing his past self, he might understand how he became the hero he is in the present. He could pass on some of his present - day knowledge to his past self, like better combat techniques against the Mavericks. This would potentially change the course of his own history in interesting ways.
Some of the Mavericks might be very confused at first. They'd see Megaman X in a time where he wasn't supposed to be. This could throw off their plans as they try to figure out what's going on.
There could be epic battles. Maybe the characters from Megaman Starforce and Megaman X would team up to fight a powerful common enemy. They might combine their unique abilities, like the Starforce's EM Wave powers and X's advanced weaponry.
One common theme is self - discovery. When X travels through time, he often learns more about himself and his capabilities. Another theme is the alteration of history. Many stories explore what happens when X tries to change events in the past or future.
Well, she might try to prevent some of the tragedies that befell her family. For example, she could warn Ned Stark about the Lannisters' treachery, which could change the entire course of the story. Maybe she'd also use her assassin skills to take out threats before they even emerged.
In this fanfiction, they could end up changing the past in unexpected ways. For example, if they prevent a certain event from happening, it could have a huge impact on the future. They might have to deal with the consequences of their actions, like new villains emerging or relationships being altered. And it would be a real struggle for them to figure out how to fix things and get the timeline back on track.
Maybe Sakura travels back and has to stop Madara from making a huge mistake that would doom the future. It could be an exciting story of her trying to convince him with her knowledge of what the consequences would be.
She could encounter godly beings with extraordinary powers. For instance, she might meet a god who can control the elements and has to figure out how to interact with such a powerful entity.
He could prevent some of the major tragedies that happened in his life. For example, he might be able to stop Uncle Ben from being killed. This would change the entire course of his life as Spider - man. He may not become the brooding hero we know, but rather a more carefree person who uses his powers more for fun at first.
Perhaps in the fanfiction, Mega Man and Mega Man X meet in a virtual world created by a mad scientist. The virtual world is filled with distorted versions of their old enemies. They have to work together to find the core of this virtual world and shut it down. Along the way, they share their experiences and upgrade each other's abilities, leading to a new and more powerful form for both of them when they finally face the scientist.
First, you should have a clear idea of the plot. Are you going to create a new villain for them to fight? Or maybe a story about their training days. Then, study the characters well. Know their personalities, abilities, and how they interact in the original games.
