I was reading the comic Emperor Joker

[AdamGomez1987]

And I was wondering, in the very last comic if anyone has read it, how did all of the super heroes die?

They show Flash's suit getting caught in barb wire, Aquaman having half of his body off, they show Green Lantern getting chomped, and the most confusing is Wonder Woman turning to clay with all sorts of little thorns around her clay body and then there's Plastic man getting owned by stretchness.

I'm more curious how each of the 3 Robins died, unfortunately they didn't give any detail on that.

I know they're opinion of the imagination but I like to get a POV for anybody that's seen the comic.
