Hayden Panettiere and Milo Ventimiglia are going to make Comic-Con just a little more special. The NBC stars have just joined the upcoming “Heroes” panel, which will take place in San Diego on Saturday, July 25.

They’ll join the already announced stars Jack Coleman, Masi Oka, Adrian Pasdar and Zachary Quinto, along with guest stars Robert Knepper, Dawn Olivieri, Ray Park and Madeline Zima. Oh, and naturally creator Tim Kring will also weigh in.

A never-before-seen trailer for the fourth season, titled “Volume Five: Redemption” will first be shown to Comic-Con fans, followed by a Q & A session.

“Heroes” Season 4 debuts with a two-hour premiere on Monday, Sept. 21.
