Some Fire Emblem characters have the ability to use magic. If they were to combine their magic with Saitama's physical strength, they could potentially create new and powerful attacks. For example, a mage could cast a spell on Saitama to enhance his already incredible strength, allowing him to punch with even more force and cover a wider area. Also, characters with support abilities like healers could keep Saitama in top shape during long battles, which is something he probably wouldn't really need but it would be an interesting combination nonetheless.
The Fire Emblem characters often have different weapon proficiencies. If Saitama were to pick up a Fire Emblem weapon, like a sword or a lance, his strength would make him an even more formidable force. He could probably swing a sword with such force that it would cut through multiple enemies at once. And the Fire Emblem characters could learn from Saitama's simple yet effective fighting style, which is basically just 'punch really hard' and apply some of that straightforwardness to their own combat strategies.
For example, if we consider Frozone's ice - making ability and Genos' fire - based attacks in a fanfiction context. They could create a really unique balance. Genos could provide the heat source and Frozone could use his ice to direct and shape it into powerful ice - fire attacks. Also, Elastigirl's stretching ability could be used in combination with Tatsumaki's telekinetic powers. Elastigirl could stretch out her limbs and Tatsumaki could use her telekinesis to fling Elastigirl around like a weapon, reaching far - off enemies.
Well, Naruto's shadow clone jutsu could be really useful in a fight alongside Saitama. The clones could distract enemies while Saitama gets in a powerful punch. And Saitama's super strength could help Naruto in situations where brute force is needed more than ninjutsu. For example, if they had to break through a really thick and magically reinforced wall.
Saitama's one - punch ability would completely overpower most of the beings in the Overlord world at first glance. However, Ainz has a vast array of magic and strategic abilities. He could potentially use his knowledge of magic and the terrain in the Overlord world to his advantage against Saitama, even if he couldn't defeat him directly. For example, he could create illusions or traps.
Another aspect of a crossover fanfiction could be the villains. The powerful villains from Fire Emblem, like Grima, might face off against Saitama. Grima with all its dark magic and power would still be no match for Saitama's one - punch ability. This would create a really interesting dynamic as the Fire Emblem characters would have to deal with the fact that their most feared enemy was so easily defeated by an outsider.
If we consider how their powers would combine, first of all, the Powerpuff Girls' ability to sense danger could be really useful for Saitama. He often just stumbles upon villains, but with the girls' power, he could be more proactive. Also, Saitama's power might inspire the Powerpuff Girls to train harder. Their combined powers could create some amazing combat strategies. For instance, Bubbles could create a force field around Saitama as he charges towards a powerful enemy, and then he could deliver his signature punch from within the protected area.
Well, Spider Man's ability to climb walls and swing from webs could be used to quickly move around in different terrains. Cheetah's super - speed could be used to quickly close the gap between them and an enemy. They could use these abilities in a chase scenario, where Spider Man swings ahead and Cheetah runs on the ground below, cutting off the escape routes of a villain.
Naruto's shadow clone jutsu could have a new twist. Instead of just creating clones for battle, the clones could be used to perform tasks around the One Punch Man universe, like helping to rebuild after a villain attack. And his ability to use nature energy could be combined with Saitama - like strength, allowing him to deliver punches that not only have physical force but also some kind of energy - based impact.
When it comes to Genos' abilities, the Avengers would be intrigued. Genos' ability to fire intense energy blasts could be a great asset in battles. Hawkeye might be thinking about how Genos could provide cover fire or take out tough enemies from a distance. But the Avengers would also be a bit worried about Genos' lack of emotional control at times. In his pursuit of power and revenge, he can be a bit reckless. The Avengers would need to work with him to make sure he doesn't go overboard. Also, Genos' loyalty to Saitama would be something they would need to understand, as it might influence his decisions within the team.
Well, in these fanfictions, characters' abilities often change due to the influence of the gamer elements. The gamer character may be able to distribute stats like in a role - playing game. So, they could boost a character's intelligence stat, which might then allow that character to come up with more complex battle plans. Another way is through item acquisition. A character might find a game - item that gives them temporary flight ability or enhanced vision, completely changing their combat capabilities in the One Punch Man world.
Well, Elastigirl's flexibility and ability to stretch could be very useful in getting into tight spaces in Gotham's architecture, like the sewers or narrow alleys. Batman could use her as a sort of living grappling hook in some situations. Dash's super speed could be used for quick reconnaissance or to deliver messages quickly between different parts of the city. And Batman's gadgets could enhance the Incredibles' abilities. For instance, he could give them some of his advanced communication devices to improve their teamwork. Also, Violet's invisibility and force fields could provide cover for Batman during his stealth operations.
