Marvel has announced the addition of three new cast members to Marvel Studios' upcoming Netflix series "A.K.A. Jessica Jones." The new characters represent potential allies and enemies for the ex-superhero series lead, played by Krysten Riter.

"The Originals" and "Power Rangers RPM" alum Eka Darville will play Malcolm, a character described as Jessica Jones' neighbor "whose own journey will intertwine with her quest in a surprising way." Erin Moriarty, who previously played Audrey Hart on "True Detective," has been cast as Hope, "a young girl who becomes a client of Alias Investigations." Lastly, Wil Traval ("Red Widow," "All Saints") will take on the role of an an NYPD cop (no character name yet revealed) who "takes 'protect and serve' very seriously."

While Hope and the NYPD officer don't appear to have counterparts in the Marvel Comics universe, it's possible that Darville's Malcolm will be based on Malcolm Powder, a supporting character from Brian Michael Bendis and Michael Gaydos' original "Alias" comic book series that provides the basis for "A.K.A. Jessica Jones." In the comics, Malcolm was a high school student that used his encyclopedic knowledge of superheroes to help Jones out with her cases -- even if Jess constantly tried to dissuade him from helping. Malcolm Powder appeared throughout the initial "Alias" series, but has not been seen in the comics since that book's conclusion a decade ago.

These actors join a cast that has filled out considerably over the past few months. In addition to Krysten Ritter as Jones, the series will also feature Rachael Taylor as Trish Walker, David Tennant as Kilgrave, Mike Colter as Luke Cage and Carrie-Anne Moss as an "powerful ally." Production has already begun on the series, as indicated by the first photos of Ritter on the show's Bronx set. The 13-episode series, written and produced by Melissa Rosenberg, will premiere sometime this year on Netflix, following the debut of "Daredevil" in April.
