Based on stupid current continuity, we are in the 8th iteration of the universe. Every Ragnarok that we reference happened in the 7th. In this stupid version, Odin and Mjolnir were around a million years ago as the "prehistoric Avengers". And possibly Thor's mother is a mutant human cavewoman Phoenix host.
Missing the character we all appreciate is like missing pre-crisis Superman before DC threw continuity to the wind and started hurling stories against the wall.
So I really dont think the breaking of the Ragnarok cycle is still true, as that happened in the 7th iteration.
I'm not sure where that leaves us or where I am going with this, I guess I am basically just complaining now about the state of Marvel writing.......
So Mother earth no longer real mother of Thor?
