The Hollywood Reporter reports that the already large cast of Heroes is balooning ballooning toward ginormous -- which is now officially a word, FYI. NBC confirmed that Jessica Collins, formerly of ABC's The Nine, will be playing Sophie, a new super-powered female.

The article describes her as a mysterious woman who works at the organization tracking all the heroes, which I assume is Primatech Paper Company -- unless there is a new organization to be introduced.

In addition to Collins, Dania Ramirez, Dana Davis, David Anders, and Lyndsy Fonseca are all expected to join the cast in the second season.
