Thor the Mighty Avenger #7

Thor the Mighty Avenger #7 pits the God of Thunder against overwhelming odds, as Chris Samnee's cover shows a small but determined Thor — hammer in hand — being buried beneath a crushing pile-on of massive, goggle-eyed robots. The sheer visual contrast between Thor's compact figure and the towering mechanical swarm closing in around him makes this one of the more inventive covers of 2011. Comics Bulletin's quote right on the cover says it all: this series started great and only kept getting better.
