She could have the same powers as Spider - Man, like super strength, agility, and the ability to stick to walls. But maybe her web - slinging is a bit different, like she can create different types of webs, perhaps ones that are stronger or have special properties.
His web - slinging would work great for mobility. He could swing between buildings in the RWBY cities or even use it to quickly move around in the forest areas. His super strength would help him in combat against the Grimm, allowing him to punch them hard or hold them back.
His spider - sense would be a very useful power in the MHA universe. Given that many battles in MHA involve sudden attacks and surprises, Spider - Man's ability to sense danger before it happens would give him an edge. He could use this to warn his MHA allies and prevent ambushes. Also, his super strength would make him a formidable force against the powerful villains in the MHA world. He could hold his own against even the strongest quirks, like All - Might's strength - based quirk.
She could meet him at a Stark Industries expo. Spider - Man is there to stop some villains who are trying to steal Stark's latest tech. Tony Stark's daughter is also present, and she witnesses Spider - Man in action. After he defeats the villains, she approaches him and starts a conversation, expressing her admiration for him.
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.
Spider - Man's powers are unique. His super strength and agility would put him in a good position among DC heroes. However, compared to Superman's near - invincibility and flight, he might seem less powerful. But Spider - Man's wall - crawling and spider - sense could give him an edge in certain situations. For example, in a fight in a city with lots of tall buildings, his wall - crawling ability would be very useful.
In 'Daughter of Spider - Man' fanfiction, the theme of self - discovery is quite common. She discovers her powers, but also discovers her place in the world. Another theme could be friendship. She may have friends who are either normal or have powers too, and these relationships can be crucial. There's also the theme of facing challenges. Whether it's a new villain or a personal struggle, she has to overcome difficulties, which is a fundamental part of her story in these fanfictions.
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.
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.
Spider Man's character would grow in terms of his detective skills. Since Batman is a great detective, he would pass on some of those skills to Spider Man. This would make Spider Man not only rely on his spider - sense but also on his deductive reasoning when facing enemies. Also, he might become more secretive like Batman, which could change his relationships with his friends and family as they might not understand this new side of him.
Spider Man would probably be very protective. He'd use his agility and strength to keep the kid out of danger. For instance, if they were in a fight scene, he'd quickly web - sling the kid to a safe place.
