Warning: contains spoilers for Heroes Reborn #1!
The Avengers: Endgame depiction of Thor is of a man who has lost everything, including his hammer, his friends, family, and even his physique - and yet the version of the God of Thunder recently appearing in the comics is in a far, far worse state. The new Heroes Reborn event has changed many things and certainly promises a darker Son of Odin. Written by Jason Aaron with art by Ed McGuinness and Mark Morales and colors by Matthew Wilson, Heroes Reborn #1 depicts a world drastically different than the Marvel universe fans know and love, one in which Thor is not the hero he once was - or, rather, ever was.
Two weeks prior to the events of Heroes Reborn #1, Blade, the vampire-hunting Daywalker, woke up in an unfamiliar reality. Doctor Doom has become the Juggernaut, Venom has bonded with the Red Skull, and while heroes still appear, they're not the familiar Avengers. Blade discovers that Tony Stark, Carol Danvers and Jennifer Walters never became Iron Man, Captain Marvel, and She-Hulk, respectively. The presence of the Squadron Supreme of America meant that the Avengers never formed. Blade all but confirms this when, seeking answers and allies, he comes across Thor at a bar - disheveled, disillusioned, and in despair.
The would-be Gof of Thunder sits at a bar and listens to Blade recall Thor's story in the original timeline: Thor was cast down to Midgard by Odin sans powers to teach his son humility, at which point Thor found Mjolnir and soon after became an Avenger. But in this timeline, Thor never found his hammer - or his fellow Avengers - and after years of searching, has all but given up. What's more, Thor claims his father is dead. He wants no part of the Avengers or any other advice from Blade. He just wants to be left alone. The many cups littered around Thor, his large beard and unkempt appearance all tell a story of a man who cannot move forward in life and is content to remain exactly where he is.
What makes this version of Thor so much more tragic than his MCU counterpart is not so much what happened to him as what didn't happen. The MCU Thor fought with alongside fellow Avengers, gaining new experiences, changing as a person, and eventually saving the world many times over. But this Thor not only lost his hammer and his friends, he never found them in the first place. He never became an Avenger, and all the moments he shared with his friends and comrades-in-arms never happened. Thor, quite literally, does not know what he is missing.
With Blade determined to set the world on the correct path, it remains to be seen if Thor will ever become as legendary and as loved as his mythical namesake, to say nothing of his Earth-616 counterpart. While the hammer does appear before him at the end of the issue (unwittingly summoned in a drunken fit of anger), years of depression and loneliness can change a person, even an Asgardian. Yet if the Thor from Avengers: Endgame can find peace and happiness, so, too, can this Thor from Heroes Reborn.
