Here's why:
* Comic Book Deaths are Fickle: In comics, death isn't always permanent. Characters are resurrected, brought back from alternate realities, or their deaths are retconned (rewritten).
* Different Continuity: The Fantastic Four has had various runs with different writers, artists, and storylines, leading to different canons and timelines.
Some Notable Deaths
However, here are some significant deaths in the Fantastic Four that are generally considered impactful:
* The Thing (Ben Grimm): Though he's not truly dead in the main continuity, Ben Grimm has died several times in alternate timelines or storylines. One notable death is in the "The Thing is Dead" storyline where he sacrifices himself to save his teammates.
* The Human Torch (Johnny Storm): Johnny Storm has also died several times. One notable death is in the "Fantastic Four: The End" storyline where he's killed by the Mad Titan Thanos.
* Sue Storm (Invisible Woman): Sue Storm has died in a few storylines as well, often being revived later. For example, in the "Fantastic Four: The End" storyline, she's killed by Doctor Doom.
Other Characters:
Other notable deaths include:
* Reed Richards (Mr. Fantastic): Reed Richards has died in alternate timelines, but his death in the main continuity is a topic of ongoing debate and speculation.
* The Puppet Master: A recurring villain, the Puppet Master, was killed by the Thing in a storyline.
* Various supporting characters: Many supporting characters have met their end in the Fantastic Four universe, such as Alicia Masters, the Thing's love interest, and several members of the Future Foundation, a group of young heroes mentored by the Fantastic Four.
