The main characters in 'bitten and broken hellsing fanfic' are likely to be a mix of the original Hellsing characters and new ones created for the fanfic. If it follows the typical pattern, Alucard and Seras Victoria will probably play important roles. Alucard's power and his complex personality make him a prime candidate for exploring the 'bitten and broken' concept. Seras, with her own struggle between her human and vampire nature, could be further developed in this context. Additionally, there could be new characters that are specifically designed to be the focus of the 'bitten and broken' aspect, perhaps a human who was recently bitten and is now on the verge of losing their humanity.
I'm not sure specifically as it depends on the fanfic. But it could potentially still have Alucard as a main character. Since he is a central figure in the Hellsing series, the fanfic might focus on his reaction to a 'bitten and broken' situation, maybe one of his subordinates or an enemy. Another possibility could be Seras Victoria, who has her own journey of transformation in the original series and could be further explored in this 'bitten and broken' context.
Well, without actually reading the 'bitten and broken hellsing fanfic', it's hard to say for certain. However, considering the nature of the title, it might introduce new characters that are in a 'bitten and broken' state. But the original main characters from Hellsing like Integra Hellsing could also be main characters in this fanfic. Integra has a strong leadership role in the series, and in this fanfic, she could be dealing with the chaos caused by characters who are bitten and broken. Alucard, as always, might be there to either cause or solve these issues.
