Marvel Comics has released a new trailer for its latest event series, Infinity Wars. The video stars Infinity Wars writer Gerry Duggan, editor Jordan D. White and Marvel Editor-in-Chief C.B. Cebulski discussing the shocking death of Thanos at the hands of the mysterious Requiem in Infinity Wars Prime #1, along with how the series sets up the character mash-ups in the spinoff series, Infinity Warps.

White kicks off the trailer with three words most fans never thought they’d hear: “Thanos is dead.” From there, the trailer begins shows the final pages of Infinity Wars Prime #1 as Requiem cuts off Thanos’ head, as well as the hacking of the Mad Titan’s body into tiny pieces. “We’ve told fans this is the summer of secrets,” Cebulski said. “And if you didn’t believe us before, after Infinity Wars Prime, you definitely have to.”

“I didn’t pitch [Thanos]’s death lightly,” Duggan added. “It’s integral to the story of Infinity Wars. You’ve all seen Thanos with the [Infinity] Gauntlet, and this is a new story.”

Duggan would also compare Act I of Infinity Wars to The Warriors, with each gang possessing one of the six Infinity Stones: Adam Warlock has the Soul Gem; Captain Marvel is the owner of the Reality Stone; the street-level criminal Turk Barrett has the Mind Stone; Drax is the keeper of the Power Stone; Doctor Strange has the Time Stone; and Black Widow was given the Space Stone from a resurrected Wolverine.

We also learn additional details regarding Infinity Warps, which takes different heroes from across the Marvel Universe and combines them into one new character. According to White, every character in the Marvel Universe will take part in the Infinity Warps. “In Infinity Wars #3, we create something called the Infinity Warps. All the characters in the Marvel Universe get smashed together into these new characters,” White said. “Iron Man and Thor get smashed together into Iron Hammer. Spider-Man and Moon Knight get smashed together to become Arachknight.”

Finally, the bigger question for Infinity Wars is the identity of Thanos’ killer, Requiem. What is Requiem going to do with the Infinity Stones? Of course, a couple of different theories have surfaced regarding who is behind the Requiem armor. The list of suspects ranges from Thanos’ adopted daughters, Gamora and Nebula, to Terraxia (Thanos’ dead lover) and Phyla-Vell (a former Captain Marvel and Quasar). As it stands, Requiem has delivered the opening salvo for Infinity Wars by killing Thanos.
