Overall, Hellsing Ultimate is reasonably close to the manga. Some minor details might be different, but the main story and the core characters remain consistent. The animation style also does justice to the manga's dark and intense atmosphere.
In Hellsing Ultimate Abridged Fanfiction, it's a fan - created work that builds on the Hellsing Ultimate world. It could involve the same characters like Alucard, Seras Victoria, and Integra Hellsing. The abridged aspect means it may cut out some parts of the original story and add its own twists. Maybe it gives a different perspective on the battles between the vampires and the Hellsing organization. It could also introduce new dialogues that are full of inside jokes and references that fans of the original would appreciate.
Yes. The English dub for BlazBlue Central Fiction exists. It adds to the accessibility and appeal of the game for English-speaking players, allowing them to immerse themselves in the story and gameplay with familiar language.
You could also focus on an alternate universe where the events of Hellsing Ultimate took a different turn. Maybe Integra made different decisions early on, which led to a completely different power structure within the organization and different battles against the forces of evil.
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.
