>>84450695Thor starts with Donald Blake, a doctor with a messed up leg, finding a stick that when hit against the ground, turns him into Thor and lets him fight rock aliens.
Then he gets an ongoing where it's eventually revealed that Donald Blake was created by Odin to teach him humility. The Donald Blake identity continues until Simonson;s run starts in the 80s, where, after Beta Ray Bill manages to steal Mjolnir, Odin unmakes Donald Blake because Mjolnir used to turn Thor back into Blake if he stopped holding it for a minute.
Thor starts using Sigurd Jarllson as an alias, until architect Eric Masterson merges with Thor when Thor's soul gets separated from his body for magic reasons.
Thor eventually comes back, Masterson becomes Thunderstrike and dies a heroic death, Thor dies in Onlsaught.
After Onslaught, Thor gets killed by the Destroyer, and gets merged with Jake Olsen for the entire run of Thor v2. Then Loki destroys Asgard, Thor REALLY destroys Asgard, and Thor eventually comes back when Donald Blake starts existing again.
Also, at some point Thor was Siegmund AND Siegfried in the Middle Ages.
