The original version of Killer Shark was a modern-day pirate. Killer Shark was later portrayed as a Nazi agent. It may be that these two versions really constitute two distinct characters. Further research is needed about this.
Killer Shark's real surname is "Haifisch," which happens to be the German word for "shark."
