I think squaring either of these cruddy stories is pointless in my view. The later is more of an outlier to me and seems more of a shock moment to start a run than anything else.

It made no sense at all given past indications either as Odin in the past and Galactus alaways regarded one another as threats and dangerous.

To me it seems more like a bad example than THE example to indicate much of anything.

For that matter, there are other examples of this Thor having less luck against what should be weaker foes to this point.
