Originally designed to help Thor hold himself together after a curse placed on him by Hela made his bones as brittle as glass and unable to heal if damaged; and rendered him truly immortal and unable to die no matter how severe his injuries. Thor eventually broke his arm in battle with the Marauders because of the curse, and Tony Stark helped his old friend by designing a sort of "armored cast" for Thor's left arm
Thor was also forced to grow a beard to hide the scars on his face around this time, which Thor would keep for a long time (his beard is usually associated with Thor's armored look). Thor designed the rest of his armor around the "armored cast", forging it at Damascus Steel, where he had once reforged Mjolnir. Even after Thor's body is restored, he would occasionally don the armor for heavy battles, usually at points when he also had a beard
The first version of the armor Thor owned was eventually destroyed during an intense battle on Pangoria. It is presumed Thor soon after rebuilt the armor, possibly once again at Damascus Steel. Thor also donned the battle armor to fight an evil duplicate of himself after being weakened from another curse, this time placed on him by Loki. Thor eventually creates other armored looks over the years that look different from the original armor.
