Antichrist (League of Extraordinary Gentlemen)

In 2009, the final volume of The League of Extraordinary Gentlemen: Century, the Antichrist of Oliver Haddo is brought into creation. It serves as the series' (thus far) final antagonist, acting onto its destructive whims.

Origin and Role
During the conclusion of 1969, Mina has an encounter with the grotesque spectral form of Haddo that attempts to possess her body in the meantime. Due to a talisman, he is unable, so he moves to possess her associate, a dark arts instructor named "Tom". In Tom's body, Haddo disappears into King's Cross and emerges in Platform 9 3/4.

In the flashbacks of 2009, a horrific massacre occurs at a school for magical students, shown from the first-hand perspective of a student. Said student is shown murdering several with his wand in the same manner as a school shooter. Eventually, the student crosses paths with Haddo, who is, by the present, reduced to a living head within a cage. It is shown that Haddo, while in the form of "Tom", created his Antichrist by marking a "boy who lived". (If it has not become evident just yet, the Antichrist of the League universe is, tragically, none other than Harry Potter.)

Following the incident, the Antichrist retreats to his home of Privet Drive where he awaits further instructions from Haddo. Eventually, Allan, Mina, and (female) Orlando catch up to his location and do battle. Crudely, the Antichrist disposes of Allan using lightning emitted from his crotch. However, the Antichrist is cut short by the appearance of Mary Poppins (who appears to serve as God within the League universe). Poppins ultimately defeats the Antichrist by reducing him to nothing more than an illustration, washed away to nothing by the coming rain.

Personality
Quite unfortunately (but fittingly), the Antichrist has the mannerisms of an aggressive teenager. This is mostly evident in his conversation with Mary Poppins where he brags of his greater importance and then pleads uselessly when she disposes of him. He is also shown to be quite crude, as seen by the aforementioned "lighting from his nethers" attack.
