He could develop the ability to combine his chakra with his Spider - Man powers. For example, he could infuse his webs with chakra to make them stronger or even give them different properties like being able to cut through objects. Another new ability could be using his shadow clones in combination with his Spider - Man agility. He could send clones to different locations while swinging around with his webs, creating a more complex battle strategy.
One possible new power could be energy projection. He could shoot out webs of energy instead of just the physical webs. This would not only enhance his offensive capabilities but also give him a new way to interact with his surroundings and immobilize foes from a distance.
In fanfiction, Spider - Man could gain the power of teleportation. This would allow him to quickly move around the city and reach crime scenes faster. He might also develop the power of super strength in his legs, enabling him to jump much higher and farther than before. Additionally, the power to manipulate time, even if just for a few seconds, could be a great addition.
Well, in SI fanfics about Spider - Man powers, often we see the exploration of his spider - sense. It could be made more acute or perhaps have some new features added. And his web - slinging is another cool power. Some fanfictions might have him create new types of webs with different properties, like electrically charged webs for combatting enemies.
Some fanfictions give Spider - Man the power to heal himself much faster. This means that even after a really tough fight, he can get back on his feet in no time. In addition, he might have the power to fly using his webs in a more efficient way, like creating a sort of web - glider that can carry him long distances. There could also be a power where he can project his thoughts into the minds of others, which would be useful for both communication and misdirection.
Their powers could combine in a way that Naruto's chakra enhances Spider - Man 2099's physical abilities. For example, his strength and speed could be increased even more. Also, Spider - Man 2099 could use Naruto's shadow clone technique to create multiple copies of himself to confuse enemies while swinging around on his webs.
In some SI fanfictions, Spider - Man's power of web - slinging is given a new dimension. Instead of just using it for swinging around, he can use it to create complex structures for trapping enemies or even as a means of long - distance communication by vibrating the webs in a certain pattern. His super strength is also sometimes depicted as being variable, depending on his emotional state, which is an interesting take.
Fanfiction writers often expand on Spider - Man powers by thinking about new ways to use his existing abilities. For instance, they might write about him using his web - shooting to create elaborate traps across a whole city block. They also might give him more control over his strength, like being able to adjust it precisely depending on the situation.
Another way their powers could combine is in the area of mobility. Spider - Man can move quickly through the city, but Elsa can create ice bridges and paths that can cross large gaps or even over water. So, if they were on a mission together, they could use these combined abilities to get to places faster. For example, if they were chasing a villain who escaped to an island, Elsa could freeze a path across the water and Spider - Man could swing them both along the path at high speed.
His sense of humor might change. While he still has his quippy nature, it could be more cosmic - themed. For example, he might make jokes about black holes or alien cultures. His empathy could also expand as he meets different beings from across the universe and understands their plights.
