Marvels made its debut at San Diego Comic-Con in a new IMAX trailer for attendees.

The two-minute sneak peek features our first glimpse at Medusa’s hair-raising abilities, as King Black Bolt’s resilient warrior wife goes after power-hungry brother-in-law Maximus. In the footage, Maximus also warns Black Bolt of what the humans might do if they were to discover their superhuman species.

Marvel’s Inhumans makes its ABC debut on Friday, Sept. 29, with a two-hour premiere starting at 8/7c. Those same two (of Season 1’s eight) episodes will be exclusively screened in IMAX theaters four weeks earlier, starting Friday, Sept. 1.
