Milo Ventimiglia (Heroes, upcoming The Whisperers) has been set to guest star in a major, multiple-episode recurring arc in Season 1 of Gotham. Appearing first in episode 19, Ventimiglia will play Jason Lennon, aka the Ogre. While this Ogre shares a nickname with a character from the DC Comics, it is a different character, not from the DC canon.

Handsome, wealthy and seductive, the Ogre is a serial killer who has been preying on the young women of Gotham for nearly a decade, luring them into his web and confronting them with a series of "tests" as he searches for his perfect mate. When the women fail to live up to his impossible standard, Lennon disposes of them quickly and viciously. His obsessions, combined with Gordon's determination to bring him down, send both Gordon and Lennon - and those around them - on a course toward tragedy.

Since Milo Ventimiglia's Ogre appears so late in the season, it seems likely that fans will see him every week from episode 19 until Gotham closes out its Season 1 run. It's possible that the character could also come back next season, since Fox announced last month that the series was renewed for Season 2. Gotham airs Monday nights at 8 PM ET, with the first season continuing on Monday, February 9 with the new episode "The Scarecrow".
