History
Kaymar was an anthropomorphic dog who worked as a travelling salesman on the sea-floor after his former subjects of Atlantis throw him out for being too materialistic. He set up shop and waited for customers alongside him companion Markup, however nobody showed up until a transformed J. Hamilton Hampster mindlessly wandered through. This forced Kaymar to move his wares out of his path. Not long after this a frog appeared and Kaymar attempted to sell him a suit.[1]
Trivia
This character is the Larval Earth counterpart of the Sub-Mariner of the Silver Age. He is not to be confused with the Sub-Marsupial, the Larval Earth version of the Sub-Mariner of the Golden Age—even if in the Marvel Universe both of them are the same character.
