Well, one way it could unfold is that Dracula sees the Avengers as a new source of power or a threat to his own existence. Maybe he tries to manipulate some of the Avengers, like Loki, who has his own devious nature. He could offer Loki power in exchange for helping him take over the world or at least gain a stronghold. Dracula's powers of mind control and immortality would be a huge asset in such a plot.
One common trope is the 'forbidden love' between the OC and Dracula. The OC, whether human or vampire, finds themselves drawn to Dracula's dark allure despite the danger. Another is the 'newbie in the vampire world' trope, where the OC is a newly turned vampire trying to navigate the rules and power dynamics in Dracula's domain.
Tony Stark would likely be cocky and taunt Dracula, which might make the vampire more aggressive. Steve Rogers would be more diplomatic, trying to reason with Dracula at first before engaging in combat. Thor would see Dracula as a worthy adversary and would approach the fight with honor.
In this Avengers assemble dracula fanfic scenario, the Hulk might be a wild card. He could just smash Dracula without much thought. But Dracula is not an easy foe. He has centuries of combat experience. Black Widow and Hawkeye would also play important roles. Black Widow could use her combat skills and intelligence to find Dracula's lair and Hawkeye could shoot his arrows, perhaps ones with silver tips which are effective against vampires.
First, you need to establish their initial meeting. It should be intense and full of conflict, like the OC being captured by Dracula's minions and brought before him. Then, through a series of conversations, they start to see each other's perspectives. For example, the OC might question Dracula's methods of ruling the night, and Dracula could be intrigued by the OC's courage.
I think the Hulk could be a major rival too. The Hulk's brute strength is almost limitless. If Dracula were to face the Hulk, he would have a hard time. The Hulk doesn't really fear much, and his simple yet effective way of fighting would be a challenge for Dracula. Even if Dracula tried to use his mind - control powers, the Hulk's rage might make him resistant to such attempts.
To create an engaging Dracula OC fanfiction, research is key. Learn about the original Dracula story, its themes, and the setting. When creating your OC, think about how they fit into this world. Are they a new vampire in Dracula's lair? Or perhaps a human trying to resist his charm? Build tension in the story by creating conflicts between your OC and the existing Dracula lore characters.
One common theme is the struggle against Dracula. The OC often finds themselves in a battle against the powerful Dracula. Another theme is the exploration of the dark and spooky world of Castlevania. The OC discovers the secrets and dangers of this world. Also, self - discovery for the OC is common as they face new challenges and powers.
First, give him a clear backstory. For example, if he has superpowers, explain how he got them. Was it an accident, genetic, or something else? Second, give him flaws. He can't be perfect. Maybe he's too impulsive or has a fear of heights which can create interesting situations in battles. Third, give him relationships. He could have a family member he's trying to protect or an old friend who has turned bad.
The OC should have a unique backstory that ties into the existing Avengers lore. For example, if the OC has powers, their origin could be related to an event in the Marvel universe. Also, their personality should complement the Avengers. If they're too similar to Steve Rogers, it might be boring. So, they could be more carefree while Steve is more serious. And they should have a clear motivation, like wanting to protect the world or seeking revenge for a past wrong, that aligns with the Avengers' overall goals.
