My personal favorite Namor villain is introduced…Tiger Shark!
Todd Arliss is a swimmer with a spinal cord injury who seeks healing assistance from Dr. Dorcas, who also happens to be a mad scientist who has kidnapped Sub-Mariner. Dorcas injects Arliss with tiger shark DNA, which somehow heals his broken back and gives him super strength. Tiger kicks Sub-Mariner’s ass.
And then he kidnaps Lady Dorma, who seems to only serve as a hostage in all these Roy Thomas Namor stories, and then takes over Atlantis. I have to say, Atlantis is a pretty lame city. They seem to be kicked around by…Everyone.
In the end, Namor beats up Tiger Shark and reclaims his throne as Prince of Atlantis.
The cover to #6 is a classic.
Grade: B-. Way above average for a Namor comic, but only somewhat above average compared to other books you could have read in 1968.
This is among the top 10 John Buscema comics of all time.
