In a parallel universe, the DC cinematic franchise rules while Marvel struggles to catch up. A fan-made YouTube trailer offers a glimpse of that universe, with a surprisingly well-made edit of the Justice League trailer in the style of Avengers: Infinity War that not only unites the DC cinematic universe with the Arrowverse (and 2011’s Green Lantern), but also pits the DC heroes against the Mad Titan, Thanos.

On Monday, a YouTube channel named Live Breathe Media, run by an individual who identifies as “Aaron,” uploaded a video simply titled Justice League: Avengers Infinity War Style. It’s a straightforward title, because the video is literally the Avengers: Infinity War trailer edited with clips of Justice League, Batman v Superman, Green Lantern, and episodes of Arrow and The Flash.

The most interesting thing is that the video doesn’t dance around the fact that it’s Josh Brolin’s Thanos, a Marvel character, who does most of the disembodied voice over. Nor does Aaron try to photoshop Thanos to make him resemble Darkseid. It’s just Thanos, crossing over to DC to fight the Justice League. Cool.

Another fun thing the trailer does is assemble a unique live-action iteration of the Justice League: It’s basically all of the cinematic Justice League — Ben Affleck as Batman, Henry Cavill as Superman, Gal Gadot as Wonder Woman, etc. — with Ezra Miller’s Flash swapped for TV’s Grant Gustin. Joining the team are two emerald heroes, the Green Arrow (Stephen Amell, from Arrow) and Green Lantern, of course played by Ryan Reynolds. Sadly the heroes from Supergirl, Legends of Tomorrow, Black Lightning, and Constantine are left out, but this Justice League is pretty stacked anyway.

Justice League has come and gone, and it’s only a few months until Avengers: Infinity War blows everyone away. While DC fans may be in mourning for how Justice League turned out, this remixed trailer is enough to get excited for Infinity War all over again.

Avengers: Infinity War will be released on May 4.
