Another possibility is that a new character, a mad scientist perhaps, has found a way to manipulate the Venom symbiote from afar. This villain uses the black tentacles to bind Mary Jane as part of an experiment or to draw out Spider - Man. He might be interested in studying the connection between Mary Jane and Spider - Man and thinks capturing her with Venom's power is the best way to do it.
It could be Eddie Brock himself if he loses control over the Venom symbiote. His darker side might take over and use the black tentacles to target Mary Jane for some reason, like she might have something he wants or she stands in the way of his plans.
One possible plot could be that Mary Jane gets caught in a dangerous situation where Venom's black tentacles are being controlled by an evil force. Maybe she's lured into a dark alley and the tentacles suddenly wrap around her, restraining her movement. She then has to use her wits to try and escape or call for help.
Yes, there are many non - adult Mary Jane Watson Venom fanfictions. You can start by looking on fanfiction websites like Archive of Our Own. Just use the search terms 'Mary Jane Watson' and 'Venom' and filter out any inappropriate content tags.
The Vulture could be a great villain. He could target Mary Jane to get to Spider - Girl, thinking that Mary Jane is a weak point. His aerial attacks would pose a new challenge for Spider - Girl, especially if Mary Jane is caught in the middle.
One common theme is the idea of an unexpected alliance. Since Venom is usually seen as an antagonist, a fanfic might explore how he and Mary Jane could team up for a common goal. Another theme is the exploration of Venom's complex nature in relation to Mary Jane. How she reacts to his dual - nature of being both a powerful and dangerous entity.
It could be a dark wizard. Dark wizards are often antagonists in fanfictions. He might have created the black tentacles as a way to capture Kairi for some dark purpose, like using her powers for his own evil deeds.
One idea could be that Mary Jane and Black Cat team up to solve a mystery in New York City. They start off as rivals but gradually realize they have more in common than they thought and end up becoming friends.
In fanfiction, Black Cat is often portrayed as a complex and alluring character. She might be shown as a rival to Mary Jane for Spider - Man's affections. Mary Jane, on the other hand, is typically depicted as the more traditional love interest. Fanfiction writers may explore different scenarios where Black Cat's criminal past clashes with Mary Jane's more innocent and stable personality.
One possible reason could be that Mary Jane has different life goals. Maybe she wants to focus on her career and she sees Peter as a distraction. For example, if she is aiming for a high - profile job in journalism or acting, she might think that a relationship with Peter would take too much time and energy.
A good non - adult plot idea is that Mary Jane discovers a way to temporarily suppress Venom's more violent tendencies. She then tries to train Venom to be a force for good in the city. Or perhaps Mary Jane is accidentally exposed to a small part of Venom's symbiote and gains some minor powers, and she has to figure out how to control them while also dealing with Venom who is both intrigued and a bit jealous of her new abilities.
A common theme is jealousy. Since they both have a connection to Spider - Man, there's often jealousy between Black Cat and Mary Jane. Another theme is the contrast between their lifestyles. Black Cat's life of crime and adventure compared to Mary Jane's more normal life.
