Incognito

Incognito is a sadomasochistic vampire from "the dark continent," a reference to Africa. Though physically androgynous, he is generally thought to be male. He only appeared in the anime and serve as its main antagonist. Though physically similar to Jan Valentine, the two do not appear to have any connection other than Incognito's role in creating the FREAKS.

History
Incognito first appeared when Alucard sensed his presence when he arrived in England, he eventually occupied a castle and performed a ritual on an unidentified man. Incognito began operations out of the Baobhan Castle. Hellsing later entered the castle to investigate. Under orders to aprehend supposed IRA terrorists, the SAS 22nd Regiment ordered Hellsing to stand asside. It is uncertain, but possible, that Incognito deliberatly leaked information to the SAS about the possible terrorists both to delay Hellsing and to provide Incognito with troops as the entire SAS unit was later turned into FREAKS.

Despite Hellsings withdrawl, Alucard continued to investigate and came face to face with Incognito for the first time. The two exchanged greetings of a sort, establishing that they were both original vampired armed with human weapons and were prepared to engage one another when Incognito told Alucard of the danger to Integra. Intending to eliminate Integra, Incognito had ordered the Baobhan Sith, Bubbancy to turn her into a ghoul. Alucard was quick to return to Integra's side and eliminated Bubbancy. With Alucard otherwise occupied, Incognito completed his efforts to transform the 22nd Regiment of the SAS into FREAKs and orders them to attack Cambridge and Trafalgar Square.

Aware of the potential threat that Helena could poss to his plans, Incognito attacked and devoured her. Despite Incognito's power, Helena was able to force her way partly free of Incognito's body and provide information to Seras Victoria before being beheaded and killed by Incognito. With him being aware of the trap at the Tower of London, he then decide to turn the tables on the Hellsing forces by causing a fierce battle against each other which has drawn the attention of the British army and framing the Hellsing Organization as terrorists. After the SAS vampires were destroyed, Alucard and Seras then confronted him but they were overwhelmed by his dark magic which resulted in injuring Seras and seemingly killed Alucard (by shooting him with his favourite gun, 'The Jackal').

He then kidnaps Integra and prepares for a ritual to summon Sett but was interrupted when Alucard comes back to life and deactivates his level one restriction by Integra's command. They then had a rematch but the outcome resulted in weakening Incognito, he then asks for Alucard's true identity and Alucard shows his true face briefly to him (as Vlad III Dracula) and Alucard impales him afterwards, killing him.

Abilities and Weapons
Like Alucard, Incognito is an original and ancient vampire. He is a master of Dark magic and a cunning opponent. His dark magic, representend by the glowing sigils covering his body, allows him to withstand what would otherwise be a killing shot from the Casull or Jackal. His powers enable him to phase part of his body in response to an attack. When Alucard fired a bullet at point blank range at Incognito's eye, Incognito simply phased his head litereally negating the ability for the bullet to hit it. His magic also allows him to turn an opponents attack back on themselves such as when he hurled the Jackal's bullets back at Alucard, giving him a "taste of his own blessed silver".

Again in comparison to Alucard, Incognito wields an enhanced weapon. In Incognito's case it is an ArmsCor 40 mm Grenade launcher. The Grenade Launcher's cartridges are filled with powerful dark magic spines. When the launcher is fired, the catridge shatters launching the spines. What effect these have on a human target is never shown in the Anime, though they appear to be powerful to be of note to Alucard. When reloading is required, Incognito vommits a set of dark magic spines into the cartridge assembly of the gun. Incognito also possesses regenerative abilities that may actually exceed those of Alucard, as Incognito was able to shrug off the effects of both the Jackal and the Casull.

During the final arc of the anime, Incognito summon a hell Demon indentified as Sett (presumably the Egyptian god of chaos) and takes the demon into his body with the intent to bring ruin and destruction to everything.

In addition to his dark magic and weapon, Incognito is a cunning tactician as evidenced by his earlier match against Alucard. By throwing his FREAK vampire solders at Alucard, and encoraging Alucard to attack him, Incognito tricked Alucard into expending his amunition and then walking into the trap he had set. By trapping Alucard with his dark Magic, and depriving him of his ammunition, Incognito was able to severaly wound, and temporarily kill, Alucard.

Trivia

 * It has also been argued that, while Alucard may be inspired by, or is, Count Dracula, Incognito may have been inspired by, or be, the vampire Count Orlok, from the 1922 silent movie Nosferatu.
 * Incognito does not appear in the manga (although he has a small cameo in OVA 2) and his name comes from the literal definition of the word, "incognito". In episode nine, Alucard responds to Incognito's introduction by saying his name's "quite an enigma as well."
 * It can be argued that Incognito is an indirect reference to The Major and serves as a stand in for him in the Anime Series. Incognito claims to have been born for no purpose save to bring ruin and destruction to all while the Major says his only goal is to ignite a grand war.
