WonderCon is continuing throughout the weekend in Anaheim, but unlike San Diego Comic-Con, we haven't seen too much come out of the convention center. TNT has used the event to launch the first trailer for The Last Ship Season 2. It teases that a new enemy is coming!

The first season of The Last Ship topped the basic cable charts as the #1 show of 2014. Not only did TNT release this exciting new trailer, but they also released the first teaser poster. Both debuted during a special WonderCon 2015 panel that featured a discussion about upcoming episodes with stars Rhona Mitra, Adam Baldwin, Charles Parnell, Travis Van Winkle, Christina Elmore, Jocko Sims and John Pyper-Ferguson.

The Last Ship is based on William Brinkley's popular novel of the same name, and chronicles a global catastrophe that nearly decimates the world's population. Because of its positioning, the Navy destroyer U.S.S. Nathan James avoided falling victim to the devastating tragedy. But now, Captain Tom Chandler (series star Eric Dane) and his crew must confront the reality of their new existence in a world where they may be among the few remaining survivors. The Last Ship Season 2 will debut Sunday, June 21, with a two-hour premiere at 9 p.m. (ET/PT).
