Aquaman #43

In "To Win Is to Lose!", Aqualad wakes from injury with fragmented memories, convinced he must rescue Mera from the Sea Sorcerers—unaware Aquaman is already searching for her elsewhere. As he’s captured by a warrior race and forced into an undersea arena battle, Aquaman encounters towering sea giants and a surface scientist studying them, while Atlantis trembles under a sudden sea quake. Written by Steve Skeates and illustrated with dynamic precision by Jim Aparo, with a striking cover by Nick Cardy, this 1969 DC classic blends suspense and underwater intrigue.
