Spider-Man’s fate in Marvel Zombies is left deliberately ambiguous as the show strongly hints at his death but never confirms it outright. The finale of Marvel Zombies shows Spider-Man fighting alongside Kamala Khan, Valkyrie, and other survivors at Kamar-Taj. He is last seen getting lifted toward the mouth of a zombified wasp about to suffer his near end, while battling against Wanda's undead army.
The camera then cuts away, and we never get to see what happens to him, leaving his death or escape ambiguous. Therefore, Spider-Man's fate is technically unknown. There is a high probability he is dead, but the show never chooses to show it, opening up the possibility of some last-minute surreal intervention.
Does Spider-Man die in Marvel Zombies?

Marvel Zombies ends with Kamala waking up in a restored normal world, only to realise that it is all an illusion. Here, the show bends reality, and this adds to the unresolved fate of several characters involved. The deaths of other heroes are shown on screen, but not of Spidey, leaving his fate unclear. It can be speculated that the makers are up to something, definitely involving the character.
Even the summary of Marvel Zombies states the impending demise of all the heroes, while also mentioning that not every character falls into the same group. Spider-Man is last seen in mortal peril, and the scene heavily implies he dies with no other means to act upon or initiate an escape. Moreover, Marvel comes with an R-rating, and if they had wanted to show him dead, they likely would have shown it. But the fact that the show doesn't explicitly confirm the death leaves the ending surreal and open-ended.
Spider-Man’s status would be a major storyline in Marvel Zombies season 2, if it happens

Let us draw a parallel between Spidey and Riri Williams, who was just like Spidey was swarmed by zombies, yet later appeared in Kamala's perfect world sequence. Did she make it through? Or is it all an illusion? If Riri survived, Spidey being spared could follow the same logic. In horror or action storytelling, an off-screen "death" is often open to interpretation and can mean anything. The cutaway seems like more of a survival tease than a definitive death.
As mentioned, the official synopsis also highlights that, although the heroes suffer their end one by one while arriving to help defend Hulk, it teases an unknown ending for some characters, stating, "we don't see what becomes of them."
This is all done to establish an intriguing foundation for Season 2, following the premiere of Season 1 on September 24, 2025, with all four episodes released simultaneously for binge-watching. The finale teases that Kamala's dreamlike world has begun to glitch, suggesting it may be nothing but an illusion. This further keeps the fate of the characters unknown until the next season arrives.
Brad Winderbaum, the executive producer of Marvel TV, hinted that Season 2 depends on viewership. If it happens, Spider-Man’s status is one of the dangling threads fans most want resolved.
