- A large man materializes in town, and starts to tear the place up. The Mighty Thor tries to stop him, but the seemingly mindless berserker is just as strong as he is, and proceeds to kick the crap out out of him. Thor, in desperation to protect the innocent bystanders, powers up and hits him so hard it kills him. Before he has a chance to celebrate, Balder and Loki run up, too late to inform him that his opponent was Bor, Odin's father and Thor's own grandfather.
- Loki, like everyone else, cannot remember Thor following his death in battle against the Serpent. However, unlike everyone else, he knows Tanarus is not the god of thunder, or his brother... and he's upset because he can't remember who is.Loki: You are not my brother. My brother was—was—
Tanarus: Was who... little brother?
Loki: Kill you. I will when I— when I figure all of this out.
- Thankfully an attack from Kelda (accidentally?) jogged his memory. But then in the next issue, it's clearly getting more and more painful for him to hear people call Tanarus his brother. By the end of the issue, he gets the Silver Surfer to remember, and also manages to find Mjölnir.
- Technically this was in The Avengers: Earth's Mightiest Heroes! cartoon and not from a Thor comic, but it still counts.Wasp: Should we move his hammer? Hulk maybe...
Hulk: Can't move it. Can't even lift it.
Wasp: Why not?
Hulk: Because I'm not Thor...
- During Walter Simonson's run, Beta Ray Bill showed up. In his backstory, he revealed that his race fled their home galaxy when a wave of demons began to threaten their entire species's survival, with Bill becoming their protector. Thor agrees to help him destroy the demons, in order to save the rest of Bill's race, and they track the demons to their source... Bill's home planet, converted into a Hell Gate. Bill's reaction is as you expect:Beta Ray Bill: My home! My home! What have they done to you?
- Again with the Simonson run, at one point Thor gathers the warriors of Asgard for a raid into Hela's realm to reclaim falsely-taken mortal souls. This mission includes his old enemy, Skurge the Executioner. In the successful raid Thor is mutilated and the Executioner, who used to be an honorable and worthy opponent but has since become a joke discovers to his horror that on Ragnarok he will lead the evil dead of Hel to destroy Asgard. He destroys the almost-complete Naglfar, the warship of the dead, by throwing his dimension-warping axe at it, rendering all the work invested on it worthless and delaying Ragnarok until it can be rebuilt. Hela, in a fury, sends all the hosts of Hel after them. Thor is willing to stay behind and sacrifice himself to defeat them. But then the Executioner knocks him out and explains to Balder the Brave:Executioner: They made a fool of me, Balder. They laughed at me. Everybody laughs at Skurge. Hela, Mordonna, even the Enchantress I love, they all laugh at me. Except you. Balder is too kind to laugh at Skurge. But whenever they laugh, I hurt inside. Maybe I die a little. Now I think I am dead already, and my axe was destroyed with Naglfar. So I will stay behind and the last laugh will be mine.
- And so Skurge makes an epic, badass Last Stand against Hela's hordes, killing them by the hundreds until finally, as we are told:"They sing no songs in Hel, nor do they celebrate heroes, for silent is that dismal realm and cheerless. But the story of the Gjallerbru and the god who defended it is whispered across the nine worlds. And when a new arrival asks about the one to whom even Hela bows her head, the answer is always the same: He stood alone at Gjallerbru... and that answer is enough."
- The exchange leading up to his last stand is particularly powerful, too. The realization that his 'lover' and 'allies' truly do nothing but manipulate and mistreat him was devastating. On top of that, he saw that Baldur, one of Thor's closest allies and thus one of Skurge's enemies, was the closest thing he had to a friend. His final action was to cover the retreat of the only man to show him kindness, and in doing so have the last laugh after a lifetime of being mocked. His grin says it all: after all he'd been through, standing alone, guns blazing, against the numberless hordes of Hel is exactly where he wants to meet his end.
- Also the narration all but states that Skurge's final thoughts were about his love Amora.
- Amora herself was genuinely heartbroken when she learned of Skurge's death, making her realization that she really did love him or least cared about him on some level even sadder. She even tried to resurrect him at least once, to no avail (she actually had to be stopped since her efforts were messing up the space time continuum).
- The tragic, heroic death of Bill, born of Bills. He was a mortal fry cook who fell in love with Kelda, a goddess of light. Against all odds, he successfully wooed her, but when he learned that Doctor Doom and Loki were concocting a plan to dissect Asgardians, he tried to stop them with a sword despite having no experience wielding one. Bill was mortally wounded and died, but passed on the message that saved the people of Asgard. For his courage and nobility, he was granted a Viking funeral and later taken to Valhalla — and when Kelda herself died later on, they reunited there.
- The last words of Bill, Born of Bills. He doesn't care that he's going to be honored like a god after death. All he wants is for Balder to make sure to tell Kelda that even after the arguments they'd had recently over the fact that she's an Aesir and he's mortal, he still loves her.
- The original Loki's death during Siege. Thor can only stare in horror as the Void consumes him and flies into a sobbing rage. Even after all the terrible acts Loki had done in the story and those leading up to it, Thor still loved him.Thor: LOKI!
Loki: I'm sorry, brother...
- In The Mighty Thor #4 (Matt Fraction's run), Odin and Galactus and their respective forces are fighting over who will gain control of the Life Seed. Instead of fighting head-on, Odin and Galactus engage in a psychic battle where they show each other their worst memories. Towards the end of the issue, we see Galan, a younger Galactus, investigating the impending doom of his universe. The kicker comes when it is revealed to the reader and to Galan that his wife/lover is pregnant. For a brief panel, the reader sees Galan overjoyed at the prospect of being a father, only to have his universe, his lover, and his unborn child die a few seconds later. This one memory overwhelms the mighty Galactus. I'm not one for recons, but this one was rather touching, if only for the reason that it showed that Galactus, The Devourer of Worlds, was once a normal person who had everything taken away from in a brief instance; it really hits home when you realize that he has to kill trillions every year just to keep the current universe from being completely destroyed.
- Volstagg, as a representative of the Council of Worlds, goes to visit a light elf refugee camp. He befriends a small group of light elf children, even giving them the massive amount of food he'd brought for himself. The encounter swiftly turns tragic, as an attack on the camp separates Volstagg and the children from the others. He desperately tries to keep the children safe, only for them to die a fiery, painful death in his arms. Volstagg flies into a rage and annihilates the attackers, but he is left firmly planted on the far side of the Despair Event Horizon. He starves himself, broken and unresponsive, friends and family unable to bring him out of this state until the hammer of Ultimate Thor calls to him. And so the War Thor is born, a god of thunder powered by rage and vengeance. A god who used to be one of the friendliest, most jovial gods of all.
- THOR #372 saw the debut of a new incarnation of a supernatural serial killer called The Zaniac. Realizing that The Zaniac's next victim would probably be his one time great love Jane Foster, Thor immediately flies to Jane's home, only to find that he is too late. The next six panels depict the Thunder God screaming "NO!" at the top of his prodigious lungs whilst flying through a powerful thunderstorm created by his internal anguish. The seventh panel shows a huge crater created by Thor crashing to the ground, punctuated by the immortal Son of Odin squeaking out one last whispered "no". Jane of course gets better, but that inevitable fact doesn't take an iota of poignancy from this powerful scene.
- THOR #432 featured a most pivotal clash between the God of Thunder and Loki, which ultimately ended with Thor losing it and pummeling his evil stepbrother into submission, nearly throttling him to death in the process, but in the end decides to remand his evil brother to Odin's justice, like always. It is only when the God of Mischief, in an act borne of pure spite, attempts to kill the ex-wife and son of Thor's mortal alter-ego Eric Masterson, that the Odinson finally decides that Loki is just too evil to be allowed to live. Thor, using Mjolnir, seizes upon Loki's very lifeforce and draws it out of Loki's body, effectively ending his physical existence. In the midst of doing so, an anguished and tearful Thor says goodbye to his nevertheless beloved brother, stating that he will forever remember Loki as his faithful youthful companion, with the Laufeyson cursing him with his last breath.
- The very first issue of THOR vol.2 showcased a mega-destructive battle between the Odinson and the Avengers against The Destroyer, culminating in Thor, the last Avenger standing, in the grip of the Asgardian war machine as it charges up its ultimate weapon, the Disintegration Beam. As the blast is unleashed, Captain America pontificates on his first impressions of Thor and what he means to the Avengers: "From the moment I met Thor, I knew he was something special. I realized that be he man or god, his heart was formed of an iron will and courage no other could match. His was a spirit unequalled, a nobility surpassing that of any king. Because of those factors, I never thought this day possible. And Avenger... the King- has fallen." And the penultimate panel depicting the reactions of the assembled Avengers as they gaze upon the Thunder God's dead body (Cap in wide-eyed, open-mouthed horror, the Scarlet Witch weeping into her hands, the usually indomitable Iron Man frozen in shock, and unflappable cynic Hawkeye turning his head, is heartrending.
- Jane choosing to pick up Mjolinir one last time to save Asgardia, even though it will kill her.Thori: Murder? Why you... murder self?
