The Destroyer had remained inert until Loki tricks Frost Giant Siggoth into stepping on the slag, reforming and reanimating the armor. And, as always, the armor goes looking for Thor.
Thor himself had undergone some massive changes, being cursed to be unable to die, yet not as invincible as he once was, and was held together only by his magical armor at this point.
The Destroyer, realizing that Thor would be an ideal host, kills Siggoth and tries to absorb Thor’s spirit.
The Destroyer does such damage to Hel, that Hela heals Thor’s body, and he leaves the armor to back to his own body (Thor, faking the idea of “you really got me”, had been in control of the armor the whole time to get Hela to heal his body!).
The Destroyer Returns
Hela then stopped the Destroyer with the help of Balder and Sif, casting the Destroyer (with Lorelei’s spirit) into the realm of the Great Beasts.
(This all occurs in a “Tales of Asgard” backup feature, from Thor #437-441, written by Tom DeFalco and penciled by Pat Olliffe in 1991.)
Later, Hela casts Lorelei out of the Destroyer armor and uses her guard dog, Garm, to animate the armor to attack Thor.
The Destroyer took on two Thors to get pretty sore this time...
This all happens in Incredible Hulk #461, written by Peter David penciled by Adam Kubert in February, 1998.
(Though the Destroyer didn't make the cover....usually the Hulk is a better host than that...and you'd think he'd show a little sympathy to someone grey...)
Back to Basics
Time Out for the Destroyer
Odin releases Tarene from the Destroyer armor. And, the Destroyer animates again in a story from Thor #78-79, also written by Dan Jurgens, with art by Scot Eaton, that ended up not happening due to Thor eliminating the cause of the events from the timeline.
New Thor and Destroyer
Thor drove Balder out of the armor and saved the Asgardians (and all this let to Thor #600, reinstating Thor's original numbering for a time).
Most recently, in the Iron Man/Thor four issue mini-series written by Dan Abnett and Andy Lanning, with art by Scot Eaton, the High Evolutionary, with the help of Diablo (an alchemical foe of the Fantastic Four), used the Destroyer armor to try to gain the power of the various pantheons who helped create the armor.
Interesting that the comics brought Thor and Iron Man together at this time, when Iron Man has his successful movie franchise, and Thor is starting his. Makes you think…could they be planning on putting these celluloid heroes together on screen? (Yes, true believers…the Thor movie was followed by Avengers movie, that also featured a not so little green man and a few others).
Now we just have to wait a few months, until a certain shield wielder can claim this is Captain America calling!
