Having already witnessed the shocking scene where the mighty Thor committed the unpardonable sin of slaying his evil half-brother, Loki--an act which caused Thor to be summarily banished for all time--it's time to follow up on that story and not only discover the fate of Thor but also the many hidden truths which writer Tom DeFalco would reveal, one by one, which allowed the mortal Eric Masterson to assume the identity (and comic book) of the Thunder God for the next 25 issues. As we can see, artist Ron Frenz has given a sense of symmetry to the cycle, commemorating the points at which the "new" Thor made the scene and when the original Thor would reclaim the book.
It was a generous two-year period which allowed a brand-new and more mortal point of view of the God of Thunder to play out, though there were likely more than a few readers who may have been drumming their fingers on a hard surface while waiting for this storyline to run its course. And run on it did, stringing along fans of the original Thor with one red herring after another that might reveal Thor's true fate and thus would give the impression of the book circling back to restore the character. In the meantime, DeFalco was pursuing an intriguing (if at times interminable) story where an ordinary human suddenly found himself to be, for all intents and purposes, Thor--someone whom the average reader could hopefully identify with and get behind. The flip side of that coin was that the character no longer carried the sense of grandeur and nobility of the original--no longer set apart from the likes of Spider-Man or the Avengers or Daredevil or other human super-heroes on the comics shelves, regardless of how many Asgardians DeFalco would pack his stories with to compensate.
If you'd prefer to take each of these issues in turn and follow DeFalco's intentions for portraying Masterson as well as the many diversions that teased the possible return of the true Thunder God, that's certainly a valid and perhaps even rewarding option available to you; and of course now you wouldn't have to spend nearly as much time doing so or waiting a month between issues. But for those of you who want the answer without reading through twenty-five issues of preamble, or for those who have already read the entire story when it was published but just want to refresh your memories, the PPoC promised earlier to cut to the chase and put it all together for you, and we aim to please.
Speak for yourself, Odin! Some of us non-immortals aged two years to finally get this info!
