Aquaman #63

Aquaman #63 (September 1978) promises high-stakes underwater drama as the cover — penciled and inked by Jim Aparo — pits the orange-and-green-clad Sea King against his purple-costumed nemesis, Ocean Master, who looms over him surrounded by a swarm of strange sea creatures while declaring a challenge for control of the seas. The bold cover blurb proclaims "The Return of the One Foe Aquaman Can't Defeat," setting up a brotherly rivalry that interior writer Paul Kupperberg and artist Don Newton are clearly ready to push to its limits. If you're a fan of classic DC underwater adventure, this one earns its 35-cent price tag.
