Enrico Maxwell

Maxwell is the fanatical leader of the Vatican's Special Section XIII, the Iscariot Organization. Enrico controls his organization with an iron fist. However, his seemingly blind devotion to his mission often makes his underling Alexander Anderson question his motivations. During the standoff between Alucard and the Millennium led police force in Rio de Janero, Anderson watches the scene unfold on the news with a sense of indignation and fury, while Enrico seems to revel in the ensuing violence. Enrico also has a bitter rivalry with Integra Hellsing, Bureau Director of the Hellsing Organization, due to their similar occupations and differing ideologies.

Enrico seems to suffer from a facial tic characterized by repeated wincing of his left eye, much to the amusement of fans. He also appears to drool whilst he sleeps.

In the manga, Enrico is promoted to the rank of bishop, and then very quickly to archbishop in the space of two volumes by the Pope. He is given command of the remnants of the Christian armies from the Holy Crusades, which consists of over 3,000 knights clad in medieval armor and wielding an assortment of heavy weapons with which to attack Millennium. However, he became so drunk with power that he decided London's Protestant survivors also deserved to die, and commanded his men to kill them as well. Eventually, Alucard's undead army overran his own. Enrico's helicopter was shot down by Rip Van Winkle (who at this point was a familiar under the command of Alucard), but it was Anderson who broke the armored glass protecting him, leaving Enrico to be impaled by Alucard's men. Anderson commented that Enrico had become drunk with power and rather fought for his own goals and pleasure rather than for the sake of the Vatican. With this act, Anderson felt that Enrico had become an enemy of the Vatican and needed to be killed.

After Enrico's death, Anderson has a flashback. As a small child, Enrico lived at Ferdinand Luke's, an orphanage outside Rome where Anderson lived and worked. His parents had abandoned him, likely because he was the 'son of a mistress'. Though Anderson tried to raise him as well as he could, Enrico remained angry and spiteful. He grew determined to become someone that people couldn't look down on. Enrico's determination proved to be his hamartia, as he ended up dying the same way that he had lived; alone.

In the manga, Maxwell has blonde hair and blue eyes, while both animated versions give him silver hair. He has green eyes in the TV series and violet eyes in the OVA series.
