The comicbook superhero is pretty much always on an interrupted version of the Hero's Journey Mono-myth as related by Joseph Campbell.
It's universally held that the Origin Story is the most boring part of any superhero movie and it's true. It is. It absolutely is but no audience would stand for it, if that part of the story wasn't told.
You can look at just about any superhero origin story and every part can be interrupted as landing somewhere on the the superhero ring cycle.
Call To Adventure; Check
Journey to the Underworld; Check
Mentor/Supernatural Aid; Check
Road of Trials; Check
Death and Rebirth; Check
And the big one...Transformation; Double Check
But then the comic book superhero's story goes into a loop once he hits Atonement. A superhero never returns from the Underworld.
Now Marvel's heroes usually got as far as atonement but they never really completed the Hero's Journey either.
I'll need to ponder on this some more.
