New Challengers (2018) #4

Plot

The Challengers tackle undead barbarians and a zombie-dinosaur stampede way down under in otherworldly Skartaris. Good thing they find that flock of pterodactyls, too—turns out to be handy against rogue agents setting up a super-weapon! Unfortunately, the Challengers also find their HQ destroyed and their predecessors missing. Plus, their borrowed time might be up, because the hourglass tattoos are on the fritz. All in a day’s work for the Challengers! (Face palm!)
