Walter C. Dornez

Walter C. Dornez is a hellsing member and serves as it's butler since he was young.

History
Walter has lived with the Hellsing family for perhaps his entire life. Walter was educated at Balliol College, Oxford (where Arthur Hellsing and Sir Hugh Irons were educated) after World War II, and studied philosophy and politics.

Hellsing: The Dawn records Walter and Alucard (in female form) storming Millennium's base during World War II in Warsaw, Poland,and putting an end to their first attempt at creating an army of artificial vampires.

Powers and Abilities
Despite being a human, Walter possesses exceptional combat skill on par with or exceeding many supernatural beings. During the initial Millennium assault on Hellsing, he dispatched a large force of ghouls with almost inoculate ease and confidently engaged an artificial vampire. He also appears to be very physically durable, as can be seen when he engages the Captain in The Dawn. Specifically, he was able to withstand multiple punches from the Captain, even though such blows are shown to have a fairly detrimental effect on even fully vampiric Seras. As such, it is possibly that Walter had some artificial physical enhancement as a human; a single punch from the Captain would kill any normal human easily. It is possible that the Captain was more powerful during the London incident due to having aged, but as human Walter's wires had the same effect on him in 1944 as in 1999, this appears unlikely.

His speed and agility are of particular note, and even in his old age he was able to dodge bullets from assault rifles. In his youth, Walter displayed great acrobatic skill and even as a senior citizen he still can perform exceptional feats of balance and coordination. His strength is also considerable, when the transformed Walter first appears in the manga, his micro-filaments wrap around several buildings and slice them in half, with no evidence of any physical strain on Walter's part though this can be partly attributed to his new Vampire form which would likely boost all his physical abilites. Walters primary weapons are a set of very long monomolecular razor wires, which he controls as if they where extensions of his own body. The wires are sharp enough to slice through steel and concrete with no trouble though he can use them to bind and restrain targets without damaging them. When turned into an artificial vampire by Millennium, all of his abilities where restored to their full extent. In his final battle with Alucard, he demonstrated previously unseen abilities with his wires, including stopping a high fall (slicing several buildings in half in the process), forming mesh shields to block bullets, and binding targets and controlling them as puppets.

As A Hellsing operative
In modern times, Walter serves primarily as Integra's butler and also makes special weapons for use by Hellsing's vampires, Alucard and Seras Victoria. However, he is still one of the organization's most capable operatives, wielding high-velocity monomolecular wires with incredible skill and precision. Walter's efficiency and power was so great that he earned the nickname the "Angel of Death," and even at the age of 69, Walter can still rip his way through hordes of the undead. In the manga, he also helps Integra make numerous difficult choices that Alucard occasionally poses, such as whether or not to kill innocent humans in order to achieve mission objectives.

In his youth he appeared to be belligerent, short tempered, foul mouthed, arrogant, and almost sadistic in his love of battle, as seen when insulting and mocking the Major and gleefully slicing up the Millennium soldiers. He actually appears to enjoy his brief bout with the Captain despite being outmatched, though he is not happy about Alucard not arriving earlier to help him out. He even refers to the artificial vampires as babies when they threaten Integra. As an old man, he appears to be the perfect model of an English butler; he is polite, dilligent, dutiful, and intelligent with a dry, ironic sense of humor and a merciless disposition toward the enemies of his master. He appears to have mellowed out a great deal externally, cutting apart his enemies with a cold precision rather then the glee of his younger self, and delivering only ironic and dignified insults instead of simply swearing up a storm. He appears to take great pride in being human, going so far as to say in response to Alucard's depreciation of old age that "If we cannot have our prosperity with pride, we should reject such prosperity." How much stock he actually puts into this is debatable, as his transformation would appear to contradict this comment.
