Loki: Agent of Asgard #6

Part of Marvel's "March to AXIS" lead-in, this 2014 installment of Loki: Agent of Asgard presents a striking power dynamic right on the cover by Lee Garbett: a commanding Doctor Doom strides forward, raising a heavy golden chain in his gauntleted fist, while a bound, helmeted Loki kneels in chains behind him — a trickster god reduced to captive. Writer Al Ewing and artist Jorge Coelho, with colors by Lee Loughridge, bring "Degree Absolute" to life, and the title alone hints at stakes with no room for compromise. If you've been following Loki's complicated journey as an agent caught between worlds, this issue's cover image makes a compelling case that his situation is about to get considerably more complicated.
