With the premiere of Zack Snyder's Justice League only days away, it's hard to envision how fans could be even more excited, but HBO Max has dropped yet another new trailer for the upcoming four-hour movie which gives us a bigger indication of the plans Darkseid has for Earth — and they're definitely not good.

The trailer certainly starts off on a bleak note, with Darkseid (Ray Porter) detailing his mission to take over a divided planet, especially now that there is no Kryptonian flying around to protect it. It's basically the confirmation we need that without Superman (Henry Cavill), the Earth may not be able to stand against its greatest threat. Then again, as Bruce Wayne (Ben Affleck) reminds us in voiceover, he did make a promise on the late Man of Steel's grave to assemble a team — and the Justice League, once united, will be more powerful than anything Darkseid or his loyal followers have ever faced. The trailer also gives us another good look at Superman's memorable black suit, previously teased at IGN's Fan Fest.
