Do you realize that all of them would die from a single touch by Hela except:
Thor, Hercules and possibly Valkyrie and Sersi
All of the others die with one touch.
Actually she doesn't even have to touch them, she can fire bolts of aging energy, even while she's in her astral form and can't be harmed.
Example: Group 3
Superman, Batman, Wonder Woman, Flash (Barry), Green Arrow (Ollie)
All of them age a few hundred years (and die) with a wave of her hand.
It's almost as if they were trying to fight Odin, they have no chance.
She once cursed Thor with fragile bones and an inablility to die. Could she make everyone's bones fragile?
