Well, he'd probably become super powerful. The symbiote suit could enhance his physical abilities like speed, strength, and agility. He might also gain some new jutsu or combat techniques based on the nature of the symbiote. For example, if the symbiote has some sort of dark or shadow - like property, Naruto could incorporate that into his attacks, making them more unpredictable.
Occasionally, Spider-Man does get the symbiote suit back. It depends on the specific comic series and plotlines. In some cases, it's to introduce new challenges or developments for the character.
A plot idea could involve the symbiote suit being able to communicate with other symbiotes from outer space. It could be luring them to Earth, thinking they can all live in harmony, but they actually want to take over the planet. Spider - Man has to figure out a way to stop this while also dealing with the fact that the suit is becoming more and more unruly as it gets closer to its 'friends'.
If Naruto gains a symbiote suit in fanfiction, his character development would be multi - faceted. He would initially be excited about the new power, but soon realize the challenges that come with it. His relationships with his friends could be affected. Some might be worried about the change in him, while others might encourage him to master the symbiote's power. He would have to learn self - control and discipline in a whole new way. His journey would involve not only mastering the physical abilities of the symbiote suit but also maintaining his positive and determined personality. He'd need to find a balance between using the symbiote's power for good and not succumbing to its possible negative influences, which would be a great test of his character and growth.
Spider - Man could develop a new sense of confidence, but also arrogance. The symbiote suit makes him stronger and more powerful, so he might start to think he can handle any situation alone. This could lead to him pushing away his friends and allies, like Mary Jane or Harry Osborn, until he realizes the error of his ways.
Sure, DC Comics does feature symbiotes. They play significant roles in some storylines and add an interesting element to the universe. Different symbiotes have unique abilities and personalities.
He might use his intelligence and knowledge of the symbiote's weaknesses. For example, if the symbiote has a weakness to high - pitched sounds, he could use some sort of sonic device to draw it out and then capture it. Or he could try to appeal to the part of the symbiote that once had a bond with him, by showing it that they were better together than apart.
The symbiote can make the story darker. Since it has a somewhat malevolent nature, it can bring out more of the edgier side of Spider - Man. For example, Spider - Man might become more aggressive in his fight against villains, which would change the overall feel of his battles.
The symbiote could make Naruto's relationships more complicated. For her friends, they might be initially scared or distrustful of the new - looking Naruto with the symbiote. For example, Sasuke might see her as a threat now. But as they learn that the symbiote is actually helping Naruto control the Kyuubi, they might slowly accept it.
The symbiote could make Naruto's ninja way more about adaptation. Since the symbiote brings new physical abilities, Naruto might need to adapt his fighting style. His ninja way of never giving up could be enhanced as he now has to overcome not only his normal challenges but also the challenges of controlling the symbiote. For example, if the symbiote has a weakness to certain elements, Naruto would have to find ways to work around that while still staying true to his beliefs.
