The first trailer for Marvel's Agents of S.H.I.E.L.D. season 7 is here. Fans have hardly had a moment to catch their breath after the season 6 finale, but Marvel didn't waste any time in giving us our first glimpse at the final season of the series.

The trailer was showcased at Disney's D23 Expo, where we learned a lot about the future of live-action Marvel TV, which will live on the Disney+ streaming service. But before that happens, Agent Coulsen and the gang will get the chance to ride off into the sunset.

Warning: this trailer contains massive spoilers. So those who aren't caught up on season 6 may want to check this out a little later. That said, the action kicks off by taking us way back to the past in 1931 New York City. Most of the trailer revolves around a single scene that sees several very dangerous aliens getting into a confrontation with a few unlucky police officers. One of the aliens has what can only be referred to as a face-off machine, and he's not afraid to use it. We then get a little sizzle reel of what's to come, which includes key moments throughout various points in history, as well as a Hydra reference. The trailer includes the following tagline.

"It's only a matter of time."

The implication here, as anyone who saw the season 6 finale is surely aware, is that the Agents of S.H.I.E.L.D. will be doing some time travel business in the final season. This first glimpse only offers a taste of what that's all going to involve, but it provides a whole lot of opportunities to send the show off in style. It also provides ample opportunity for other characters to return. It's been reported that we'll see Hayley Atwell show up as Agent Carter. It was also recently confirmed by Patrick Warburton that we'll see his character Rick Stoner returning as well.

Agents of S.H.I.E.L.D. will always hold a special place as the first live-action TV show of the MCU era. It also has the distinct honor of bringing Agent Coulson back from the dead. The show has, over the years, lost its major sense of connectivity to the larger Marvel Cinematic Universe. Though, it has maintained a loyal following, which has helped to carry it this far.

The core cast includes Clark Gregg, Ming-Na Wen, Chloe Bennet, Elizabeth Henstridge, Iain De Caestecker, Henry Simmons, Natalia Cordova-Buckley and Jeff Ward. The series was created by Joss Whedon, Jed Whedon and Maurissa Tancharoen. ABC has not yet revealed a release date for Agents of S.H.I.E.L.D. season 7, but it has already wrapped filming and is expected in early 2020. Be sure to check out the new trailer from the Marvel Entertainment YouTube channel for yourself.
