The Avengers look shook.

Avengers assemble — to watch the Justice League in action.

Despite the, uh, mixed response to last year’s Batman v Superman: Dawn of Justice and Suicide Squad, the reaction to the new trailer for Justice League, the next film in the DC Extended Universe, has been overwhelmingly positive.

So positive, in fact, that Marvel’s more established team of cinematic superheroes, the Avengers, look a little bit threatened in a fun new mash-up video by YouTuber DrMachakil.

“I love both Marvel and DC,” the video’s creator says, “so this is some really exciting period we live in right now.”

DrMachakil’s video has already racked up close to 2,000,000 views, while the actual Justice League trailer has almost 14,000,000.

Maybe the Avengers have a good reason to be worried…
