Well, 'black widow spanking fanfic' is fan - made fiction centered around Black Widow. Fanfics are stories written by fans. In this case, the idea of spanking might be a very specific and often not - so - mainstream take on the character. It could be a very niche and edgy form of fan - created content that might not be suitable for all audiences.
No, it's not appropriate. Black Widow is a well - known and respected character. Fanfics that involve spanking in relation to her are likely to be seen as disrespectful and inappropriate as they objectify the character in an unseemly way that goes against the character's essence as a strong female hero.
In most cases, it's not appropriate. Torture is an unethical and often disturbing concept. If it's a fanfic that involves literal torture of the Black Widow character, it goes against the values of respect and non - violence. However, if the term 'torture' is used in a more metaphorical or symbolic way to represent challenges she faces, it might be more acceptable, but it still needs to be done in a tasteful manner.
A 'black widow lemon fanfic' is likely a fan - created fictional work related to the character Black Widow. 'Lemon' in fanfic terms often implies a story with romantic or sexual undertones, but it could also just be a creative and unique take on the character in a more general sense.
In addition to the Avengers, there could be original characters created by the fanfic writers. These characters could be doctors or nurses taking care of Black Widow in a secret medical facility. Or they could be other agents who have some connection to her past. Sometimes, even villains from the Marvel universe might interact with her while she's in a vulnerable state, either to gloat or to try and make a deal with her.
Well, it might show her becoming more independent. With the symbiote, she doesn't have to rely as much on her traditional gadgets. She can trust in her new symbiotic abilities.
I'm not sure if there is such specific fanfic available. Fanfic often exists in various niches, but this particular combination might be relatively rare or hard to find. It also might not be in line with the general image and themes associated with the Black Widow character in mainstream interpretations.
Another concept could be a time - travel fanfic. Black Widow somehow gets sent to a time when Captain Marvel was just starting out as a hero. Black Widow then has to train the younger Captain Marvel and help her unlock her full potential while also trying to find a way back to her own time.
Well, 'black widow unbirth fanfic' is likely a fan - made fictional story centered around the Black Widow. The 'unbirth' aspect might be a unique plot device or theme within the fanfic. It could be that the writer is exploring some sort of reverse or alternative life cycle concept for the Black Widow character. It might also incorporate elements of her existing backstory and powers in the Marvel world, but twisted in a way that the 'unbirth' idea dictates.
