I'm not sure of specific fanfictions on this. But you can try searching on popular fanfiction websites like Archive of Our Own. They usually have a wide range of fanfictions and you might be able to find ones related to this concept by using relevant tags.
One possible plot could be about the journey of Pat and Jen preparing for the baby. They might face challenges like finding the perfect nursery, dealing with pregnancy cravings (if Jen is the one pregnant), and choosing baby names. It could also show their excitement and nervousness as they await the new arrival.
The 'pat and jen sad story' might involve a situation where Pat and Jen were in a family. Pat was ill, and Jen, who was very close to Pat, had to watch Pat suffer. They didn't have enough money for proper treatment, and in the end, Pat passed away, leaving Jen in deep sorrow.
The Autobots would likely be very protective. They are heroes after all, so they would immediately sense the vulnerability of the abused reader and do whatever it takes to keep them safe from harm. They might also be gentle and patient, understanding that the reader has been through a lot.
One common theme could be redemption. The Dantdm character might help the abused reader to overcome their past and find a new, better life. Another theme could be friendship or trust. Since the reader has been abused, they may have trust issues, and building a relationship with Dantdm in the fanfiction can be about learning to trust again.
Well, 'abused reader' might refer to a character or the reader's perception of a character who has endured some form of abuse. 'Underhigh fanfiction' could be a specific type of fan - created story set in a particular fictional universe perhaps related to a high school or teenage setting but with a different or 'under' aspect. It could imply a story where this abused character meets the elements or characters within this underhigh fanfiction setting.
In these fanfictions, the theme of transformation is quite common. The abused reader transforms from a victim into a more confident and empowered individual with the Autobots' influence. The theme of family also pops up sometimes. The Autobots can act like a surrogate family for the reader, providing love and support that they might have lacked. Additionally, the theme of facing fears is there. The reader, with the Autobots by their side, is able to face their past traumas and move forward.
One common theme is redemption. The Underswap characters might try to help the abused reader find a way to heal and move forward. Another theme could be friendship. Despite the difficult situation, new bonds are formed between the reader and the Underswap characters.
I'm not sure specifically as I haven't read it. But it might be about the adventures of Pat and Jen, perhaps their friendship, or some challenges they face together in a fictional world.
