“Marvel’s Agents of SHIELD” is colliding with another geek fandom.

“Xena: Warrior Princess” star Lucy Lawless is joining the ABC comicbook-inspired show for season two. A rep for the show confirmed that she will guest star in an upcoming episode, though they do not have her character name or description at this time.

The lack of info is no surprise, as Marvel often keeps such information under wraps for some time.

Along with playing the titular character in ’90s fantasy series “Xena,” Lawless also had roles on “Spartacus,” “Battlestar Galactica” and “Parks and Recreation.”

“Agent of SHIELD” returns to ABC on Tuesday, Sept. 23. TVGuide.com first broke the news of Lawless joining the show.
