"Galactus could probably be reanimated. Or turned into something else, or his DNA exploited etc. Or maybe even used as a trophy. Thor did not want to allow for any of that."
I am assuming you are being funny here as that is exactly what Thor did -make Glactus helmet a Trophy/Beware of Dog sign.
Although you could be right about the re-animation aspect. We all know Galactus will be back. I suspect his "death" was all part of a plan either he or he and/or Galactus planned.
I am not sure what Thor would fear or be concerned in seeing his end as since he was a youth he knew via the prophecies of Ragnarock how he would die...not to mention facing death on a fairly regular basis. I assume we are completely out of the Ragnarock cycle at this point.
Anyone else want Heimdall back in his role - exerting the same powers as Sif though. MUST Thor writers have a woman do the role of a man "better" than he did instead of just doing hers superbly?
Ha...what IS it with Thanos and gloves?!
Did not Galactus always have a back up plan to come to exist as bomral, as when High Evolutionary "killed him off"
