SPOILER WARNING: The following article contains major spoilers for Spider-Man: Into the Spider-Verse, which hits theaters on December 21.

As the various web slingers of the multiverse prepare to unite in Spider-Man: Into the Spider-Verse, the film's panel at New York Comic Con may have spoiled the death of a major character.

Fans at New York Comic Con were shown the first thirty minutes of the film. During that showing, a version of Peter Parker -- likely from Sam Raimi's trilogy of films -- fought a character who appears to be Kingpin and his henchman, Green Goblin. Kingpin then punches Parker in the chest as they battle in the collider, killing the wall-crawler. The collider is the piece of technology that somehow breaks down the barriers between the universe, allowing the different versions of Spider-Man to meet, while also threatening to destroy them all.

The footage also features Prowler chasing Miles Morales, and ends with actor Jake Johnson introducing himself a Peter B. Parker and getting pulled into Miles' universe.
