How the Hellsing characters are presented in the fandom:
Alucard: Will fuck anything that moves. Angsty VampireTM. Not even a monster, just an asshole with guns. No emotions except for sexual lust and blood lust. Nobody can control him, and if they can, they’re presented as assholes for getting in his way. He is also abusive.
Integra: Cold, emotionless bitch. Treats everyone like shit. More often than not, she’s the one standing in everyone’s happy ending. Gives 0 fucks about the people closest to her.
Seras: Basically walking boobs. “Ahhh oh nooo I’m a vampire???! Blood is super icky!!! Save me, Alucard!!”
How the characters actually are:
Alucard: A complex character who has accepted his life after death. He has the maturity of someone who is centuries old; he doesn’t angst over what could have been with his life because he knows that he has to deal with the consequences of his actions. He is a sadistic, ruthless monster, and he knows it. But, he holds those he cares about with respect and would never cross their boundaries (though he will tease them). HE HAS NEVER AND WOULD NEVER ASSAULT INTEGRA OR SERAS.
Integra: She is a calculating, intelligent human being. She has emotions, but she usually has to suppress them for her line of duty and it causes her pain. She cares deeply about the people who live in her manor- deeply enough that they are capable of breaking her heart. She is a strong, commanding leader who doesn’t take shit from anyone, but she will do everything in her power to save innocent people and the people she cares about. She would not needlessly risk lives.
Seras: Strong, kind, and amazing. She struggles to retain her humanity and manages to smile while she does it. She doesn’t take shit either, even though she has a bit of a softer personality compared to Integra. Never assume she is weak. She is also a monster, just like Alucard, and she eventually comes to terms with it. She is a badass who kicks ass and takes names, and is not a damsel in distress or a walking set of tits. Seras is someone who has looked Hell in the face and still manages to brighten everyone’s lives with her amazing attitude. She was once a police officer, and is a vampire, so SPOILER ALERT: smack her ass and she will fucking rip your arms off, not blush and giggle.
Walter: He presents a cool and collected façade. He can pass for the average butler, but don’t think for one second that a butler is all he is. He is a hard-ass killing machine who wanted to prove himself worthy of being remembered. He didn’t want to evade the history books; he wanted to be known as the man who defeated the monster, and so he became a traitor. He is a wolf in sheepskin, and he is almost as sadistic as Alucard himself. Despite this, however, he DOES care about Integra and Seras; just not as much as he cares about himself, his ego, and his petty and childish “rivalry” he has going on with Alucard.
