[3] In the United States, Flint the Time Detective aired from 5 March to 5 November 2000 on the Fox Family Channel as part of the "Made in Japan Sundays" block.

Flint, however, pulled his weight in battle when he would fight with the aid of his father Rocky Hammerhead whose partial resurrection left him a sentient talking rock with a face.

Usually, he fought against Petra Fina and her cronies Dino and Mite (very reminiscent of Marjo, Grocky, and Walther from Time Bokan), servants of the Dark Lord.

The Dark Lord himself sought to use the Time-Shifters' powers to invade the Land of Time, the creatures' home realm from whence he had scattered them.

Similar to Pokémon or Digimon, Time-Shifters originate as small, cute creatures who can "shape-shift" into much stronger forms for a time before reverting.

The series was Americanized, with characters names and some places being altered, Flint explains in episode 6 that they come from the USA instead of Japan.
