Uncanny X-Men #21

Against a blood-red sky, a pale, otherworldly figure hovers with arms outstretched above the shattered, smoking wreckage of what appears to be a massive Sentinel — its fractured mechanical bulk dominating the foreground as debris scatters through the air around it. The image, rendered by cover artist Alexander Lozano, carries an eerie, painterly dread that makes this 2014 All-New Marvel NOW! chapter feel genuinely consequential. Brian Michael Bendis and Chris Bachalo's run on Uncanny X-Men is in full stride here, and this cover promises something appropriately unsettling inside.
