The short answer
Five rival gangs — Doctor Octopus's Sinister Six, the Vulture's Savage Six, Beetle's Sinister Syndicate, the Foreigner's men and Boomerang's squad — tear each other apart over the right to bring down Peter Parker across a single night. Their backer, Kindred, is not after his death but his moral collapse, dragging his past sins back into the light. The stakes are set out below.

Sinister War: when Spider-Man's enemies fight each other… and crush him along the way
Just when Spider-Man thought he had hit rock bottom with Kindred, a far bigger war broke out: the 'Sinister War'. Published in 2021, this saga written by Nick Spencer stages a titanic bloodbath in which the Sinister Six are no longer alone… but multiplied, manipulated and completely off the leash.
The idea behind this sinister war? Pit several teams of supervillains against one another — all of them obsessed with Spider-Man — manipulated by one single mastermind: Kindred. In this organised chaos, Spider-Man is caught in the crossfire: his enemies tear each other apart for the right to finish him off… while he is simply trying to survive this hellish night.
The reader is thrown into an almost apocalyptic battle. Not only is Parker the target, but every villain team has its own stakes, its own grudges and its own internal dynamics. Vulture, the Goblin, Kraven, the Lizard, Mysterio, Octopus, Electro… every big name turns up, in a crossover that piles on references to the web-slinger's history while serving as a final test of his moral and physical limits.
Spider-Man is broken, physically and emotionally. He has no time left to question anything. The war forces him to act… and to pay for his choices, his silences and his murky past. Mary Jane's shadow hangs over it all, the ghosts of his failings resurface. This is the chapter where every knot pulls tight.
Visually, the artwork by Ed McGuinness and Mark Bagley is explosive. Saturated colours, jittery framing, blasts, tornadoes of energy and simultaneous fights in the back alleys, on the rooftops, inside secret laboratories. A genuine war film set in the Spider-Man universe.

A war orchestrated by Kindred
Published in 2021 by Nick Spencer, the saga pits several teams of supervillains obsessed with Spider-Man against one another, all of them manipulated by Kindred.
Kindred pulls the strings: psychological revenge at its peak
Behind this carefully orchestrated chaos, one single conductor: Kindred. Obsessed with Peter Parker, he pushes every one of the web-slinger's enemies to bring him down… not to kill him, but to make him suffer. His plan is not to win a war: it is to drive Spider-Man to self-destruction.
Kindred embodies a personal vendetta, fed by lies, by bargains struck long ago, by mistakes made. Peter Parker is not just targeted as a superhero: it is the man behind the mask who is under attack, his relationships, his values, his faith in his own principles.
In 'Sinister War', every enemy faction acts under someone else's influence. Between demonic manipulation and psychological trauma, Kindred turns these supervillains into emotional weapons. This is no longer a war of muscle… but a war of mental attrition. And Peter collapses.
The story shines through its complexity. It weaves a web of guilt, secrets and buried memories. Spencer revisits the great moments of the past: the Clone Saga, the tragedies around Gwen Stacy, the dubious bargains such as One More Day… It all comes back to hit the web-slinger at the very moment he is most vulnerable.
Kindred does not want to kill Peter Parker. He wants to break him.
The reader is pulled into a dense narrative, between shock revelations and painful flashbacks. The action is brutal, but it is the emotional impact that lands hardest. Peter, resilient as he is, no longer knows who to trust. Even his allies become potential enemies. Doubt takes him over.

All-out war between supervillains: Spider-Man at the heart of the chaos
What makes Sinister War so singular is its titanic scale. Five teams of supervillains — the Sinister Six, the Savage Six, the Sinister Syndicate, the men of the Foreigner and Boomerang's squad — clash in a downpour of crossfire, each of them wanting to capture or eliminate Spider-Man to break free of Kindred's influence.
The result? An insane manhunt in which Peter Parker gets no respite. He goes from fight to fight against enemies he has known forever: Doctor Octopus, Vulture, the Lizard, Kraven, Rhino, Mysterio, Morbius... They are all there, in a kind of grand finale where every blow landed is as symbolic as it is physical.
But where Peter shines is in his endurance. Despite the exhaustion, the pain and the fear, he keeps moving forward. He refuses to give in, even when everything seems lost. That resilience sits at the heart of his identity, far beyond the mask and the powers.
Mark Bagley's artwork adds a raw tension: explosions, clenched faces, gutted cities… every panel sweats urgency and brutality. The reader is plunged into a race against the clock where hope thins out page after page.
But this war is not just a show of force. It is a reflection on the loneliness of the hero. Even with allies like Black Cat or Mary Jane, Peter stands alone against the weight of his choices, alone in carrying the guilt, alone in protecting the people he loves… even from themselves.
In this maelstrom of action, the plot weaves direct callbacks to other traumatic events in the Spider-Man universe. Long-time fans will recognise echoes of sagas such as The Clone Conspiracy or Last Remains, where Peter's mental balance was already pushed to breaking point.
As the vice tightens, the question burns hotter and hotter: will Spider-Man give in… or transcend the suffering?

A gruelling conclusion, a hero strengthened by the chaos
In the final stretch of Sinister War, Peter Parker reaches breaking point. Cornered, physically broken and mentally haunted, he finally faces Kindred head-on. And this is no ordinary fight: it is a confrontation of truths, of wounds that never closed and of regrets never admitted.
What strikes you about this conclusion is that Spider-Man does not 'win' in the classic sense. He does not floor his opponent with brute force, but with his faith in who he is. With his humanity. Peter forgives. He accepts the pain. And he moves on. A rare stance in superhero comics, but one that underlines the depth of his character.
Kindred, whose identity is finally revealed as tied to the ghosts of the past, becomes a metaphor for the guilt Peter has always carried — the guilt of Uncle Ben's death, of Gwen Stacy, of all the collateral damage. But this time, he chooses to stop running from that guilt. He looks it straight in the face.
Sinister War therefore marks the end of a long descent into hell that began with Sins Rising, carried on through Last Remains and peaks here. A brilliant narrative trilogy orchestrated by Nick Spencer that will have redefined the link between Peter Parker and his most intimate traumas.
And once the carnage is over, Spider-Man is no longer the same. More mature, more resilient, more vulnerable too. But above all, more human.
