In a fanfiction where Spider - Man becomes Carnage, his mind would be filled with Carnage's bloodlust. He'd likely target his old enemies in a much more brutal way. His sense of humor would disappear, replaced with a cruel and sadistic streak. His spider - sense might be distorted, instead of warning him of danger, it could lead him towards it to cause more destruction. The city's police force would be completely outmatched, and they would have to rely on other heroes or find a way to reverse this transformation to save the city from this new threat.
Well, it would be a very dark turn. Spider - Man is known for his heroism and moral code, while Carnage is a brutal and chaotic villain. If he became Carnage in fanfiction, he might start to use excessive violence and lose his sense of right and wrong. His relationships with his friends and family would be severely strained. For example, Mary Jane might be terrified of him, and his friendship with Harry Osborn would be in jeopardy. Also, the city he protects would be in chaos as he starts to go on rampages instead of saving people.
In fanfiction, if Spider - Man becomes a spider, it would be a total transformation. His identity as Peter Parker would be almost completely lost. He would have to adapt to a new body structure. His suit might not fit him anymore, and he would need to find a new way to protect himself. Also, his enemies might not recognize him, which could be both an advantage and a disadvantage in his battles.
In a more cooperative scenario, Spider Man's web - shooting could be used in combination with Female Carnage's shape - shifting. For example, she could transform into a large structure and Spider Man could use his webs to anchor it or create a web - based mechanism around it. Their powers could also clash in a way that creates interesting visual and story - based effects, like when Spider Man's web gets caught in Female Carnage's symbiotic mass and she uses it against him.
Well, he could bring his unique powers to the RWBY world. His web - slinging ability would be really cool in the RWBY setting. He might team up with the RWBY characters and help them fight against Grimm. Maybe he'd use his agility to outmaneuver the Grimm that the RWBY teams find difficult to handle.
Maybe in the fanfiction, Spider - Man discovers that Female Carnage has a hidden side. She has some sort of soft spot for the innocent people in the city, which is contrary to what her violent nature implies. This discovery leads to an unexpected bond between them and they start to work together more closely.
One possible fanfiction could involve Spider - Man having to face off against Female Carnage in a battle that takes place in a crowded city. He might initially underestimate her power due to her being a female version of Carnage. But as the fight progresses, he realizes she's just as dangerous and has to use his wits and agility to try and subdue her without causing too much destruction to the city.
Well, if Spider - Man were in the DC Universe in a fanfiction, he'd probably have some interesting team - ups. He could swing alongside Batman, sharing their skills in the dark and on the rooftops. Maybe he'd learn some new detective skills from Batman too.
If Naruto were in Ultimate Spider - Man fanfiction, it could be amazing. Naruto is known for his determination and never - give - up attitude. He could inspire Spider - Man in different ways. Also, his unique fighting style would be a contrast to Spider - Man's web - slinging and acrobatics. Maybe they would have some friendly competitions to see who's better at what, while also working together to keep the city safe.
Well, it could be really chaotic. Spider - Man's acrobatic and web - slinging skills would be quite a contrast to the dark and gritty Gotham. He might start by trying to clean up the streets like he does in New York, but he'd quickly find that Gotham's villains are a whole different breed. Maybe he'd team up with Batman at first, but then their different methods could cause some friction.
In fanfiction, if Spider - Man turns into Venom, he might initially struggle with the new, darker impulses. Venom's symbiotic nature could make him more aggressive. He could find it hard to control his actions, like being more prone to using excessive force against villains. His relationships would also change. His friends might be scared of him at first, and he'd have to prove that he's still the good guy inside.
They might be really confused at first. Since fanfiction can have all kinds of wild and different interpretations of Spider - Man. Some Avengers might find it amusing, while others like Captain America might be a bit shocked at how different it is from the 'truth' they know.
