Sub-Mariner #66

Prince Namor faces a massive, tooth-filled threat in this October 1973 issue — the cover, penciled by Gil Kane and John Romita and inked by Mike Esposito and John Romita, delivers a stunning undersea confrontation as a triumphant, armored Orka rides atop an enormous killer whale while a defiant Namor surges upward from below, ready to strike back. The cover copy announces both Orka's boast of victory and Namor's fierce rebuttal, promising a clash between the Savage Sub-Mariner and "The Human Killer Whale" that lives up to the story's title, "Rise, Thou Killer Whale." Inside, Steve Gerber scripts with art from Don Heck and Don Perlin, making this a solidly crafted 1973 Marvel adventure for any fan of Atlantis's most tempestuous king.
