Like Alucard, Incognito is an original and ancient vampire. He is a master of dark magic and a cunning opponent. His dark magic, represented 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 out 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 becoming temporarily invulnerable. His magic also allows him to turn an opponents attack back on themselves such as when he telekinetically 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 40mm grenade launcher. The grenade launcher's cartridges are filled with powerful dark magic spines. When the launcher is fired, the cartridge shatters, launching the spines. What effect these have on a human target is never shown in the anime, though they appear to be very powerful, as Alucard has noted. When reloading is required, Incognito vomits 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. Aside from the grenade launcher, in Hellsing Episode 10 :"Master of Monster", Incognito is shown wielding a minigun and what seems to be a M2 Browning heavy machine gun.

During the final arc of the anime, Incognito summons an entity named Sett, and absorbs the demon 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 soldiers at Alucard, and encouraging Alucard to attack him, Incognito tricked Alucard into expending his own 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 severely wound, and temporarily kill Alucard.
