Still, to me, the single greatest Thor storyline is the classic Lee/Kirby "Thunder in the Netherworld" story which contains Thor and Hercules' second meeting and battle, from Thor vol. 1 #125 - 130. It's captured in Thor Masterworks #4 which I'd previously reviewed by represent below:
Thor Marvel Masterworks Volume 4
Collecting: Journey Into Mystery #121-5, The Mighty Thor #s 126-130
Written by: Stan Lee
Drawn by: Jack Kirby
Why? Guys, it doesn’t get any better than this!
In the earliest years of Thor’s comics, you got the impression that Stan and Jack couldn’t really focus on our favorite thunder god. In fact, for quite a long time these two legendary creators weren’t even on goldilocks’ title, with the creative chores’ being passed off to Larry Leiber, Joe Sinnott and others. The stories, as a result, were fairly spotty and inconsistent in quality. All that started to change around the time of Thor Masterworks Volume 2 when Stan and Jack took the reigns back. However, despite some involvement with the hosts and hoards of Asgard, throughout Thor Masterworks volumes 2 and 3 Stan and Jack still relegated Thor mostly to Earth-bound superhero status, the notable exception to which being the glorious “Tales of Asgard” supplemental series that used to ride in the back of Journey Into Mystery. All that changes with this volume of 1966 reprints. Here Stan and Jack put the mythological cosmic spanning wonder, glory and action squarely in this comic. While this Masterwork volume opens with an knock-down battle with the Absorbing Man right in the hallowed halls of Asgard, Journey Into Mystery #125 takes Thor’s readers on an explosive whirlwind six issue story that must rank as one of the singe greatest continuing Thor adventure epics ever created. It’s due to this titanic tale that this Thor Masterworks volume is the one I’ve most wanted to hold in my hot little hands. Thank you, Marvel, for finally publishing it!
Check this out! Journey Into Mystery #125’s “When Meet The Immortals!” depicts Odin, Thor’s enraged father, commanding the forces of Asgard to attack his son for revealing his identity of Dr. Blake to the mortal Jane Foster. Hercules whom Thor first and last met in his Thor Annual #1, in the mean time, has made his way to New York and, having foiled a robbery by hurling lamp post through the getaway car, is seeking to woo the very same Jane. Having overcome all of Asgard’s forces in Odin’s furiously violent Ritual of Steel to reunite with Jane, Thor is incredulous that Hercules is rebutting him in defense of Jane who was hurt by Thor’s absence. The ensuing battle, in “Whom The Gods Would Destroy!” pits Thor vs. Hercules in an all-out no-holds-barred slugfest throughout Manhattan. Victory is stolen from Thor by his angered father who, out of his love for his son cannot punish him directly but, in a display of colossally poor judgment, gives the Odinpower to a courtier called Seidring the Merciless to strip Thor of half his strength. Of course, armed with the Odinpower, Seidring then turns on Odin and takes control of Asgard (there’s a reason he’s called “the Merciless”). With Thor’s strength halved, Hercules wipes the ground with him. Humiliated, dejected and utterly defeated, no longer certain he deserves the mantle of Thunder God, Thor leaves an anguished Jane Foster to face his father’s judgment. What ensues, in “The Hammer and the Holocaust!” is an already battered but desperate Thor’s impossible victory over the Odin-powerful Seidring, a victory that nearly kills Thor but restores the power to Odin who, then, regains the throne. At the end of this issue, in a wonderful scene, a remorseful Odin carries the limp body of his beloved son away. In “The Power of Pluto,” as Thor recovers, Hercules is duped into signing a contract to replace Pluto as Lord of the Netherworld. A revived and empowered Thor, looking for round two with Hercules, comes to his aide instead against the hordes of Hades, surprising Hercules with his renewed prodigious strength. But, “In The Verdict of Zeus!” Hercules pleads for mercy from his father and seeks the help of his Olympian brethren from his plight. Due to his centuries of arrogance, however, no one on Mt. Olympus is willing to lift a finger for the son of Zeus. A monumental coincidence (thanks, Stan!) sends Thor into limbo for the Day of the Three Worlds where Thor is commanded to stake all on behalf of another. Who needs him the most? Yup, Thor’s former foe, Hercules. Thor must battle for Hercules’ freedom and, if he loses, will be doomed to rule Hades in Hercules’ stead.
This story wraps up in “Thunder in the Netherworld!” in which Thor, after having previously been beaten, humiliated, stripped of his power, and nearly killed during the prior five issues, finally gets to cut lose at full strength. And, man, does he ever! Single-handedly and with his full power at his command, Thor takes on the entire populace of Pluto’s realm in defense of Hercules who, in an ironic turnaround, has now been stripped of his power by Zeus. Thor’s battle is cataclysmic and pure Kirby goodness, as are all the previous chapters. Victory is total and glorious for Thor, defeat comes at a great price for Pluto after Thor’s rampage, and Hercules vows Thor his lifelong friendship. What else can I say? Stan and Jack are at the absolute height of their powers with this story (despite Vince Colletta’s hack-job inks). Stan really cuts lose with dialogue like, “Anger??! By the bristling beard of Odin, thou knowest not the meaning of the word! Not all the fury in the heavens - - not all the savagery on Earth - - can equal the senses-shattering cyclone of rage with is Thor, when seized by a pounding paroxysm of wrath!” It’s corny but pure Stan! And how does Thor get all that dialogue in while delivering just a single blow to Herc’s jaw? Dunno, but it’s golden! This epic spans from New York to Asgard, back to New York, then to Olympus and, finally, to Hades. It deals with love, anger, loyalty, friendship and all-out pulse pounding battles. It beautifully combines the best of mythology, science fiction and pure superhero elements. Fantastic Four and Captain America may be the more famous Lee/Kirby collaborations but none of them surpass, and few even match, this epic for sheer Silver Age Marvel magic!
Aye, verily, 'Nuff Said!!
