The idea of a vampire's origin story within the Fallout 4 setting is quite common. It could be related to some new experiment gone wrong in a Vault, or perhaps a result of exposure to some ancient and mysterious force that was unleashed during the nuclear war. And then there's the trope of the vampire's love interest. It could be a human survivor that the vampire is drawn to, creating a complex relationship full of moral and survival - based dilemmas in the harsh world of Fallout 4.
A really popular trope is the vampire as an outcast, even more so than in regular vampire stories because of the already distrustful nature of Fallout 4's society. They might be hunted by some groups who see them as a new kind of abomination in the wasteland. Also, there's the trope of the vampire having special powers or abilities that are a combination of traditional vampire powers and something unique to the Fallout 4 universe, like being able to sense radiation in a different way or having an immunity to certain types of mutated creatures.
One common trope is Roy Harper being a reluctant vampire. Maybe he was turned against his will and has to struggle with his new nature. Another could be his relationship with other vampire characters. He might form an alliance or have a rivalry. For example, he could team up with an older vampire who teaches him the ropes of the vampire world.
Well, a typical trope could be the redemption arc. Maybe the character was a villain in their past life and now, being reborn, they strive to be good. There's also the whole 'fitting into the supernatural society' thing. Since the Vampire Diaries world has its own rules and hierarchies, the reborn character has to learn and adapt. Plus, the mystery of their rebirth is often explored. What caused it? Is there a greater purpose? These are all common elements.
Another common trope is the transformation. A character in the Fire Emblem universe might get turned into a vampire, either by accident or as part of a dark plot. This then leads to their internal struggle with their new identity, as they have to balance their old loyalties and values with their new vampiric instincts.
One common trope is the 'forbidden love' aspect. Since vampires are often seen as dangerous or different, their love for a human is usually against the norms. Another is the 'vampire with a heart of gold'. Despite being a vampire, they have deep emotions and a capacity for love.
One common trope is the mysterious stranger. He shows up in Mystic Falls out of nowhere and has a dark secret. Another is the heroic protector. He sees himself as the one to save the town from all the vampire and supernatural threats. There's also the love - struck fool trope where he falls head over heels for one of the female characters, like Elena, and will do anything to win her over.
One common trope is the 'forbidden love' aspect. Since Atem is a vampire, their relationship might be seen as taboo in the story's world. Another trope could be the 'damsel in distress' where Yugi is constantly in need of Atem's protection due to his vampire - related enemies. However, this can be subverted where Yugi is actually strong in his own right.
There are several common tropes in this type of fanfiction. The 'seductive vampire lord' trope is quite prevalent. He uses his charm and allure to draw the self - insert into his world. Another is the 'outcast self - insert' who doesn't fit in the normal human world and finds a sense of belonging in the vampire world. Additionally, the 'vampire lord's dark secret' trope is often used. The self - insert may uncover something about the vampire lord that could change their relationship or the fate of the entire vampire community. This adds an element of mystery and suspense to the story.
One interesting Fallout vampire fanfiction could be about a vampire survivor in the post - apocalyptic world of Fallout trying to find a cure for their vampirism while facing the usual threats like raiders and mutants. They might have unique abilities due to their vampiric nature that help them in combat or survival.
One common trope is the 'hurt/comfort' where a character gets injured or is in emotional pain and another character helps them heal.
One common trope is the eternal love aspect. Since vampires are immortal, their love can span centuries. For example, in many stories, a vampire falls in love with a human or another vampire and they face challenges together but their love endures.
