I Saw the Naumann Elephant is the tenth episode of Battle Fever J.
Synopsis
Egos is stealing fossils of the Nauman elephant (Mammoth), to enhance the power of their latest kaijin. When Egos attacks a paleontology class, Akebono Shiro (Battle Kenya), who had been homesick for the outdoors of Africa, arrives to protect them. Unfortunately when he encounters the Egos kaijin, he is outmatched. Meanwhile, the Nauman Association is holding a contest to archeologists who can discover the Nauman Grave. Figuring this as ploy to expedite their fossil gathering efforts, Shiro masquerades as a reporter to infiltrate the Nauman Association and expose Egos.
