Well, 'Merlin is whipped fanfiction' could potentially be about Merlin being in a relationship where he seems to be under the control or influence of someone else to an extreme degree. It could explore how his character changes due to this dynamic, maybe showing his loyalty being tested or how he copes with being in such a position. For example, if it's in a romantic relationship, it might depict how he sacrifices his own needs for the sake of his partner.
You could start by looking on popular fanfiction websites like Archive of Our Own (AO3) or FanFiction.net. Just use the search function on those sites and type in'merlin is whipped' to see if any relevant stories come up.
I'm not sure specifically as it could be about many things. It might be a fanfiction where Captain America (cap) is in a situation where he's 'whipped' which could mean overly smitten or devoted in a relationship within the Avengers universe.
In a more humorous take on the 'Merlin tied to a bed' fanfiction, it could be that Merlin has fallen ill and the overly - protective Gaius has tied him to the bed to make sure he rests. Merlin, being the active person he is, complains constantly. Arthur comes to visit and teases Merlin about finally being still for once. Meanwhile, Merlin tries to convince Arthur to let him loose, promising that he'll be fine. Eventually, Gaius relents and unties Merlin, who then immediately starts bustling around the room.
If Merlin died in the fanfiction, it could trigger a series of tragic events. The balance of power could tip, and the villains might seize the opportunity to attack. It could also bring out hidden strengths in the remaining characters as they try to cope with the loss.
One more idea is that Merlin is tied to the bed in a dream - like state created by an ancient magic. In this dream world, he is faced with his deepest fears and insecurities. His friends in the real world notice his strange behavior and try to wake him up. Merlin, while in the dream, has to find the source of the magic that is binding him and break free. Through his inner strength and the memories of his friends, he manages to do so and wakes up, having learned more about himself and his magic.
If Merlin is a Dark Lord in fanfiction, it could be an interesting exploration of the 'nature vs. nurture' concept. Maybe he turned dark because of the constant fear of being discovered and persecuted for his magic. His actions as a Dark Lord might include taking over Camelot or exacting revenge on those who wronged him in the past. It gives a whole new perspective on his character.
One common theme is redemption. Gale often has to atone for his actions during the war in many fanfictions. Another theme is love and loss, especially related to his relationship with Katniss. There's also the theme of survival, as Gale continues to fight for a better life in District 12 or in the new world order. And the theme of power and responsibility, as he may take on new roles in the post - Hunger Games society.
I'm sorry, but the idea of 'Clary Gets Whipped' sounds rather disturbing and might involve non - consensual or inappropriate themes. I would recommend looking for more positive and healthy Clary - centered fanfictions, like those focusing on her adventures or her relationships in a positive way.
