There could be many fan - made stories about Black Widow's weight gain. However, in the official Marvel canon, there's no such specific story arc focused solely on her weight gain. Maybe some alternative universe stories or fan fictions might explore this concept, but it's not a mainstream or official plot point.
Black Widow is mainly known for her combat skills, espionage, and complex character backstory in the Marvel universe. Weight gain isn't a common theme associated with her. However, if we were to imagine a story about it, it could be something like she gets injured during a mission and has to take a long break from physical activity. During this time, she starts to gain weight. But this would be a very different take on the character, and not something that fits the typical image of the Black Widow we know from the mainstream stories.
As far as the official Marvel lore goes, no. But in fanfiction, there could be some. Maybe a story where she has to go undercover in a role that requires her to gain weight to fit in. It could be an interesting twist on her character, but these are just creative ideas that exist outside of the main Marvel continuity.
I'm not sure which specific 'Black Widow weight gain story' you are referring to. There could be many fictional or even some personal interpretations related to the character Black Widow having a weight gain story in fan - made concepts or alternative storylines.
One possible story could be that after a long mission where she was injured, Black Widow had to take some time off. During this recovery period, she wasn't as active as usual. She started to enjoy the simple pleasures of home - cooking delicious but calorie - rich meals. At first, it was just a little bit of extra weight from the lack of exercise and the good food. But as time went on, she noticed her clothes fitting a bit tighter. However, she didn't let this get her down. Instead, she used it as motivation to gradually get back into her training routine, showing that even superheroes can have fluctuations in their physical state.
One reason could be a change in her lifestyle. For example, if she had to go into hiding and couldn't maintain her normal intense training routine. Another reason might be an injury that limited her physical activity, causing her to gain weight as she couldn't burn as many calories. Maybe she also had some emotional turmoil and turned to food for comfort.
One possible story could be that Black Widow is injured on a mission. She has to take some time off to recover and during this time, due to the inactivity and the medications she is taking for her injury, she starts to gain weight. When she finally recovers, she has to work hard to get back to her former fit self.
It can show her vulnerability. Gaining weight might make her feel less confident in her physical abilities at first. For example, she might struggle with simple acrobatic moves she used to do easily. This can lead to her having to find new ways to be strong, not just physically but also mentally.
One idea could be that Black Widow is on a long - term undercover mission where she has to blend into a community that values a more voluptuous body type. So she gradually gains weight as part of her cover. Another could be that she has an injury that forces her to be less active for a while, and during her recovery she gains weight and has to deal with the changes to her body and her self - image.
In the story of Black Canary's weight gain, perhaps she has some sort of medical condition. Hormonal imbalances, for example, can lead to unexpected weight gain. It could also be related to stress. High stress levels might cause her to overeat or have a disrupted metabolism, which would result in the increase in her weight.
One common story could be about a man who started a sedentary job. He used to be active but now sits at a desk all day. He began snacking constantly, especially on junk foods like chips and soda. As a result, he gradually gained weight over months.
There are various types of stories on DeviantArt regarding women's weight gain. Some might focus on the emotional journey of a woman dealing with unexpected weight gain, perhaps due to a medical condition or a change in lifestyle. Others could be more of a fictional or fantasy - based story where weight gain is part of a magical transformation or a unique plot device.
