"Heroes" alum Milo Ventimiglia has joined the cast of Fox's "Gotham." As announced by Warner Bros. TV on Wednesday, he'll appear in a multi-episode arc as a serial killer named Jason Lennon, dubbed "the Ogre" -- unrelated, WBTV makes clear, to the DC Comics character of that name. He's slated to appear in the 19th episode of the show's currently ongoing first season, which will likely air in March.

Here's the official description: "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."

Ventimiglia addressed the casting on Twitter:

Heading to @Gotham to see my friend @ben_mckenzie. Add a little madness to an already great & intense show. Very excited. @warnerbrostv. MV- Milo Ventimiglia (@MiloVentimiglia) February 4, 2015

Ventimiglia was one of the main players on NBC's "Heroes," playing Peter Petrelli, though he is not slated to return in follow-up miniseries "Heroes Reborn." In more specifically comic book-based previous roles, he's voiced Spider-Man Noir in Disney's XD animated series "Ultimate Spider-Man," and Wolverine in the English dub of "Marvel Anime: Wolverine."

"Gotham," a Batman prequel detailing the early days of Jim Gordon, Bruce Wayne and many familiar villains, airs 8 p.m. Mondays on Fox.
