Now moving on to his chronology
Journey into Mystery # 118: Loki manipulates a hunter into finding the Destroyer Armor. Thor follow and a fight ensures. Thor seem unable to harm the destroyer, and the Destroyer is capable of wielding Thor's hammer. Destroyer energy attack is capable of slicing through Thor's hammer. Destroyer then using magnetic force to pull Thor down on the ground. Destroyer then uses force beam to liquidify the floor and turn it into Asgardian diamond trapping Thor.
Destroyer then unleashes a bolt of elemental power, which Thor himself acknowledges will turn Thor into another element the moment it touches him.
Journey into Mystery # 119: Destroyer elemental power is about to turn Thor into a different element but Loki using his magic manages to turn him intangible, weird part is destroyer believe he can change the frequency of his attack to harm the intangible Thor. We don't get to see this part because Thor becomes solid again. Destroyer unleashes bolt of molten force to turn the ground of temple into river of lava. Thor drops a million tons arc of solid rock upon Destroyer which doesn't even slow him down. Thor gets hold of the hunter whose essence revived the Destroyer, Destroyer warns him that he is forced to destroy so he is going to use his most destructive power, the disintegration beam, but Destroyer chooses not to harm his own body and the soul flows from Destroyer armor into his human form stopping the Destroyer armor in track.
Marvel Handbook 1984 collaborates the whole incident
Thor Annual # 2: Loki who has been banished and imprisoned in "non-space" sends his mental bolt to earth to awaken the Destroyer. Destroyer awakes , unleashing an unimaginable force gushing upwards from the rubble, hurling giant boulders into the air with the fury of an exploding nova. Destroyer is giving out massive energy, enough raw, living power to shatter a planet. Destroyer casually defeats Hiemdall and is going to for the kill, against none other than Odin himself. He stomps Volstagg on his way. He is opposed by an army of Asgardians but he with one single sweep of his fist shatters every sword within reach though they were not but twigs. He goes on pwning Asgardians as if they were nothing. Odin himself is pretty concerned that Destroyer has come to kill him. Thor the goes all out on Destroyer, manages to drop him on the ground but cant defeat him. Destroyer than start generating heat bolt described as being more potent then a dozen flaming suns. He is face to face with Odin about to try and kill him with his disintegration beam, but Odin with help of Balder locates Loki, stops time, and manages to sever Loki's connection to the Destroyer stopping it in its tracks.
Marvel Handbook 1984 backs the whole incident
The Mighty Thor # 150: Loki and Hela manipulate Sif into merging with the Destroyer and send to earth to help, now de-powered Thor, against the Wrecker. Destroyer stomps the wrecker, whose enchanted crowbar breaks upon hitting the Destroyer.
The Mighty Thor # 151: The story starts with a de-powered Thor fighting against the Destroyer, whom Sif is holding back as much as she can. In the middle Odin gives back Thor his full power, but he is still struggling. Destroyer opens his visor unleashing his disintegration beam but Thor manages to avoid it.
The Mighty Thor # 152: With all his godly powers returned Thor is still helpless against the Destroyer armor, but the armor is defeated once Norm Queen, in order to save her life against Ulik, withdraws Sif spirit from the Destroyer upon Balders request.
The Mighty Thor # 224: Professor Clement Holmes who has found the destroyer after his last fight tries to awaken the destroyer and the destroyer does awaken using his very soul. Every time destroyer awakens it becomes more and more difficult to defeat him because destroyer learns from each activation and becomes stronger.
Looking for Thor destroyer finds Hercules and find ensures. As expected Hercules find himself unable to defeat Destroyer who starts throwing him around like a baby. Thor intervenes but physically Thor himself is outmatched so he uses his hammer to BFR Destroyer into a river, but Destroyer comes back.
The Mighty Thor # 225: Thor isnt fairing any better against the Destroyer but when Hercules finds professor body the soul of the professor leaves the destroyer living him un-animate again.
The Mighty Thor # 228: Firelord no longer wants to be Galactus herald, but Galactus will only let Firelord go if he finds a replacement. The replacement is given in the form of Destroyer Armor that Galactus makes his herald and leaves.
Marvel Handbook 1986 backs the whole incident
Fantastic Four # 172: So Destroyer, who is now the herald of Galactus has found Counter Earth. High Evolulationary, on the artificial moon is trying to hold Destroyer at bay with his Null Force but Destroyer is coming closer and closer and finally lands on the artificial moon. Ben Grim is send to stop the Destroyer but Destroyer knows its just a means to delay him rather than a true contest of strength. Sue comments on how Destroyer is not interested in the fight "The Destroyer's down almost as if he is letting Ben beat him. As if even he is beginning to realize that there can be no end to this fight". Destroyer Armour goes limp as if he his knocked out upon Galactus's arrival.
Fantastic Four # 173: That last issue we saw Destroyer Armor defeated by Thing, which is weird given Destroyer Armor has had Thor and Hercules stark helpless against him. This is explains why that happened. To directly quote Galactus
"You think you have won a significant victory defeating the one called Destroyer"
"Yet you cannot know that since becoming by herald he has been powered by the most minuscule portion of my own nigh inexhaustible life force"
"And rather than waste even that tiny spark in useless battle with such a mindless brute as yourself i preferred to mentally withdraw it from him. So that what you call "defeated" was a mere lifeless metallic shell"
The Mighty Thor # 265: So when Galactus was busy fighting, and as seen in the actual event stomping High Evolutionary, Loki who is currently in Odin thorn managed to teleport Destroyer Armor home (oddly enough Galactus never notice Destroyer missing nor did he attempt to retrieve him from Loki O_o..). Destroyer possessed by the power of Balder is unleashed upon Thor.
Thor as always goes all out against Destroyer but is almost defeated before the warrior 3 intervene. Destroyer then with a single gesture swats them away like flies. Thor however manages to get up, blind destroyer with a throw of a giant pillar and seemingly escape. Destroyer starts looking for Thor but Thor attacks him from behind and the battle renews Thor is still unable to do anything to put Destroyer down (so yeah nothing has changed :p)
