One of the main themes is rivalry. Their long - standing competition in the field of science is often a central focus. It can be about who is the better scientist or who can come up with the more amazing invention.
One popular dexter x mandark fanfiction is 'The Rivalry Transformed'. It explores a different side of their relationship where they have to team up for a common scientific goal and in the process, start to see each other in a new light.
Dexter and Dee Dee's relationship might become more cooperative. Since they are going to be siblings to the new baby, they might start to work together more often. For example, they could team up to decorate the baby's room. Instead of Dee Dee constantly barging into Dexter's lab, she might start to ask permission more politely because she realizes that Dexter is also stressed about the new baby coming.
A plot could involve the family preparing for the new arrival. Dexter and Dee Dee could be sent on errands to buy baby supplies. Along the way, they get into all sorts of wacky adventures. Maybe they accidentally mix up the baby stuff with some of Dexter's lab equipment at the store. And as the mom's due date approaches, there could be some chaos in the house as everyone tries to get everything ready, with Dexter constantly getting distracted by his lab work but still wanting to be helpful for his mom during this special time.
Well, Dexter's origin story begins with his traumatic childhood experience. He witnessed his mother's brutal murder in a shipping container filled with blood. This event, along with his own psychological makeup, led to his fascination with blood. Harry, his father, noticing Dexter's abnormal behavior, trained him in the ways of the code. So, Dexter became a killer who hunted down bad guys, hiding in plain sight as a normal, albeit a bit odd, forensic expert.
In this story, Dexter might be a character who is on an 'ego trip'. He could be someone who is ambitious, perhaps overly so. He might be constantly seeking validation, power, or recognition. His actions throughout the story could be a reflection of his egotistical nature. For instance, he may strive for success in his career or personal life not for the intrinsic value but to boost his own self - image and satisfy his ego. His character development could also be centered around learning to control or reevaluate his ego as the story progresses.
Definitely fiction. Dexter is a fictional character and the storylines are made up to engage and thrill the audience. The events and scenarios presented are not based on real-life occurrences.
Probably 'Dexter by Design' is also among the popular ones. It has a great plot that involves Dexter's interactions with other complex characters and some really exciting and unexpected events.
Since I don't know the actual story, it's hard to say if there's a moral. However, if it's a humorous story, the moral might be not to take small, embarrassing things too seriously.
