Guardians of the Galaxy #17

Part of the "Grounded" arc, this 2017 issue puts Gamora front and center — green-skinned, purple-clad, and charging forward with a clenched fist and fierce intensity that commands the whole cover. Behind her, a remarkable assembly of Earth's heroes surges into action: Black Panther, a roaring lion-like beast, a figure in white, Ms. Marvel sprinting through a burst of light, a hovering Captain Marvel in the upper corner, and more, all rendered with Arthur Adams's characteristically detailed and dynamic linework. With Brian Michael Bendis writing and Valerio Schiti on interior art, this is cosmic Marvel storytelling at a compelling intersection of street-level and galaxy-spanning action.
