The relationship between Anderson and other characters in Hellsing is also a popular theme. This could include his complex interactions with Alucard, Integra, or Seras. Some fanfics might focus on how they might form alliances or have conflicts in different scenarios.
One common theme is the exploration of Anderson's past. Many fanfics try to dig deeper into his backstory, like his upbringing and how he became a member of the Iscariot Organization.
One common theme is the clash of different power systems. Naruto has chakra - based powers and the Hellsing world has vampire powers and weaponry like the Helsing Organization's anti - vampire guns.
A common theme is the clash of cultures. Naruto's world is full of ninja clans and honor, while Hellsing has a very different set of values centered around vampires and the fight against the undead. So, the fanfics often explore how these two different cultures interact.
The theme of self - worth also comes up a lot. Anderson's actions towards Sherlock can be seen as his way of trying to boost his own self - worth. He feels overshadowed by Sherlock and so he resorts to actions that might bring Sherlock down, as seen in 'The Search for Significance' where Anderson's every move against Sherlock is related to his own internal battle with his self - image.
Often, there are themes of self - discovery. In the fanfics, Anderson and Heinkel might learn more about themselves through their interactions with each other. And of course, there could be a theme of loyalty. They might show loyalty to each other in different situations, like when facing challenges or enemies.
Friendship is a common theme. Alexander and Anderson Blacklaggon are often depicted as having a strong bond. They support each other, have each other's backs, and their friendship might be tested but always endures.
One common theme is power struggle. Kai is a character associated with power, and when an oc is introduced, there's often a battle for dominance or influence. Another theme is the exploration of abnormal psychology. Kai has a very distinct and often disturbing psychological makeup, and the oc can serve as a contrast or a catalyst for further exploration of his mind.
There are also fics that focus on the idea of redemption. Given Anderson's religious beliefs, he might see it as his mission to redeem Seras from her vampiric state. This theme allows for deep exploration of moral and ethical questions within the context of their relationship. It can also lead to some very emotional and thought - provoking storylines as the two characters navigate these complex issues together.
In 'Satan x Seras Hellsing fanfic', transformation is a common theme. Seras is constantly evolving as a vampire, and Satan's influence might accelerate or change that process. Additionally, the theme of loyalty is often examined. Seras has loyalty to the Hellsing family, and when she gets involved with Satan, that loyalty is put to the test. This creates a lot of tension and interesting plot developments in the fanfics.
One common theme is loyalty. Pip is always loyal to Seras, and this is often explored in the fanfics. For example, in many stories, he will go to great lengths to protect her.
Survival is also a major theme. The characters in both Resident Evil and Hellsing are constantly in life - threatening situations. In fanfics, this often leads to some intense and harrowing scenes. They might be trapped in a zombie - infested area from Resident Evil while also dealing with the dangerous vampires from Hellsing, and the characters have to use all their skills and resources to stay alive.
