Creators
Mike Nelson was portrayed by Lloyd Bridges in the early (1958 -1961) syndicated television series Sea Hunt, which was one of the first media ventures to bring up the theme of ecology.
The comic book version of his adventures were mainly drawn by Russ Manning, Gold Key’s artist for Magnus: Robot Fighter.
