The theme of self - discovery can also be present. Maybe the teen girl didn't know she had the power to overpower a man until a certain situation arose. Like she discovers she has a natural leadership ability that makes others, including men, follow her lead.
One possible theme is empowerment. It shows that age and gender don't limit one's ability to be strong and capable. For example, a teen girl might overpower a man in a debate by having more well - reasoned arguments.
A plot could be that the teen girl has been training in a secret art form, like an ancient form of combat. When a man, perhaps a villain in the story, underestimates her because of her age and gender, she surprises him with her skills and overpowers him in a fight.
In a magical world story, a teen girl discovers she has special powers like telekinesis. A man, who is a bit of a brute, tries to force his will on others. The girl uses her telekinetic powers to stop him. She lifts him up in the air and makes him realize that he can't just push people around, especially not her.
One story could be in a magical world where a teen girl discovers she has latent magical powers that are far stronger than a powerful wizard who is a man. She uses her powers of light to overpower his dark magic.
One possible motive could be power play. The teen girl might be in a position where she feels powerless in other aspects of her life, so she exerts power over the old man in this extreme way. Another could be a form of rebellion against social norms. By making the old man crossdress, she is challenging the traditional gender roles that society has set.
Themes in this fanfiction could include sacrifice. The Titans may have to sacrifice something, like their time or safety, to fight for the girl. Love could also be a theme, whether it's platonic love among the Titans or a romantic love for the girl. And there could be a theme of redemption if the girl has a troubled past and the Titans are helping her move forward.
Independence could be another theme. She is away from home, learning to manage on her own in a new environment for a short time, like getting ready for bed without her parents' help.
The teen could face social ostracism. People would likely look down on her actions. The married man could face a damaged reputation and problems in his marriage, like his spouse losing trust in him.
A teen girl might overpower a man in a rescue situation. For instance, if a man is trapped under a relatively small but heavy object, a strong and determined teen girl could use her leverage and physical strength, combined with her courage, to lift the object and save the man. This shows that she has the power to overcome what might seem like an impossible task.
One common theme is self - discovery. Teen girls in these stories often figure out their sexual orientation and what it means for them. Another theme is acceptance, both self - acceptance and acceptance from family and friends. For example, they might struggle with coming out to their parents. Also, the theme of first love is prevalent. Just like in any teen love story, the excitement, nervousness, and intensity of the first relationship are there.
One possible theme could be acceptance. The tall man and the short girl might have to accept each other's differences in height and appearance.
