NiseAgumon Hakase is a Dinosaur Digimon whose name and design are derived from "Imitation Agumon, PhD" (「偽 アグモン 博士」 "Nise Agumon Hakase"?). It is a genius Agumon that has a doctorate in Digital Monster studies from Digital World University. It is said that its title is plagiarized from Agumon Hakase. It is not as knowledgeable about Digimon types and territories as Agumon Hakase, and instead it rather unscrupulously spreads lies, so caution is necessary. However, as only its feelings of rivalry for Agumon Hakase are genuine, it is diligent in not leaving Agumon Hakase any research ideas, in order to inconvenience it. From top to toe it is "Nise".
