Some fanfiction describes the Venom suit as having a living - like quality. So Spider - Man's appearance could change depending on his mood. When he's angry, the suit might seem to writhe and expand, with the black symbiote spreading over his face more. It could also have spikes or other menacing features that emerge when he's in combat or feeling threatened.
Often, in fanfiction, the Venom suit makes Spider - Man look more menacing. His eyes might turn a glowing white or red, and his body could be more muscular and bulkier. The suit itself may have a more textured, almost slimy look compared to his normal suit.
The Venom suit in fanfiction sometimes gives Spider - Man a more edgy look. His traditional red and blue colors are replaced with a predominantly black suit with a large white spider symbol on his chest. The suit can also give him a longer, more flowing cape - like appendage made of the symbiote material, which adds to his overall imposing appearance.
I have no idea about this kind of fanfic. Maybe you can search on specific fanfiction platforms or communities to find the answer you're looking for.
When Spider - Man turns into Venom in fanfiction, his character changes a great deal. He loses some of his innocence. The carefree and quippy Spider - Man gives way to a more menacing figure. He might start to enjoy the fear he instills in villains a bit too much, which is a big departure from his normal self. Also, his sense of justice could become more extreme, not always following the same rules he used to as Spider - Man.
In some fanfiction, the Venom suit could give Spider - Man new abilities that he has to learn to use. Maybe he discovers he can create shadowy tendrils that can grab objects from a distance or form a protective shield. This could lead to him having to train in secret to master these powers without his friends finding out.
In fanfiction, the naruto kyuubi suit can change his appearance quite a bit. His hair could become more wild and take on a reddish tint, like it's being influenced by the Kyuubi's chakra. His eyes might glow a different color, perhaps a deep red. Also, the suit itself could be form - fitting and have a pattern that resembles the Kyuubi's fur. This makes Naruto look more intimidating and shows his connection to the powerful nine - tailed fox.
In some fanfiction, Venom might protect Spider - Man by using its strength and agility. Venom's powerful physique allows it to fend off other villains who are targeting Spider - Man. For example, it could easily overpower common thugs or even some super - powered foes.
In certain fanfiction stories, Spider - Man does accept Venom. Fanfiction writers often like to explore different relationships and character developments. They might write a scenario where Spider - Man realizes that Venom has some redeeming qualities and decides to work with him. This can lead to some really cool action - packed scenes and unique plot twists.
In some fanfictions, his upgraded suit might have a sleeker look. Maybe the armor plates are more streamlined, giving him a more menacing appearance.
Spider - Man could try to use his powers in a creative way. Maybe he uses his web - shooters to create a distraction, like making a large web - structure that collapses and causes chaos, allowing him to slip away while Venom is distracted.
With MJ, the black suit could change things too. If Peter becomes more confident in a cocky way because of the suit, MJ might not be as attracted to him. She might see him as a different person and start to pull away, which would make Peter realize he needs to get back to his old self.
His appearance would change drastically. As Venom, he would be taller, more muscular, and have a menacing look. His costume would be black with the big white spider logo. Also, his relationships would be affected. His friends might be scared of him, and he might have to prove that he is still the same person inside, despite the exterior and some personality changes.
