In a brand new trailer for Marvel's "Agents of S.H.I.E.L.D.," the Inhumans arrive in full force with some explosive new clips.

"Our whole lives have been leading to this moment," Raina says over the start of the trailer in a meta moment that could also describe the lifespan of the show so far.

This new trailer -- which reuses a few scenes from an earlier TV spot -- also highlights never-before-seen scenes with a few characters using their super abilities, including one with an oddly shaped head that shows off a shocking power set.

Among other things, the trailer reveals that Mac -- presumed dead by many characters in the mid-season finale -- is alive. Likewise, Jemma Simmons aims a gun, Bobbi issues a smackdown on a character that looks a lot like Reader and Agents Coulson and May duck an explosion.

Check out the IGN exclusive trailer below.

"Agents of S.H.I.E.L.D." returns to ABC on March 3 at 9 p.m. EST.
