Kokatorimon

Digimon Adventure
Kokatorimon was one of Etemon's underlings. He had numerous Numemon for henchmen, that he used to run his desert cruise ship. When the DigiDestined came onto his ship, he made an effort to capture them and steal their tags and crests. He turned Agumon, Gomamon, Gabumon, Tentomon and Tokomon into stone in the process, but he was taken out by Birdramon and Togemon, turning them back to normal. Kokatorimon attempted to ram the kids with his ship, but he drove it into a gigantic cactus that flipped it into the air, causing it to be destroyed - and him along with it. Another Kokatorimon was a customer at Vegiemon and Digitamamon's diner.
