This is how Grant Morrison and Frank Quitely let us know that one of the planes of existence in the Flex Mentallo miniseries is eeevil: the kid sidekicks have gone feral. Once that happens, there’s “No future. No hope.”
For anyone reading Flex Mentallo, I recommend also sampling Jason Craft’s online annotations, David Allison’s appreciation and lament for the recoloring, Sean Rogers’s critique for The Comics Journal and the many comments it produced, and Rich Johnston’s response to that critique. I’m not taking sides.
