Jacques Cousteau was presumably a human man, and the 2017 Continuum's counterpart to the original Jacques Cousteau.
Description[]
An undersea explorer, Jacques Cousteau was known to Dewey Duck as “a deep sea guy”, leading to Dewey comparing his adventures with Fethry Duck and Mitzy to being “like Jacques Dew-steau” (a pun he insisted was clever).
Behind the scenes[]
The DuckTales 2017 universe's version of Cousteau is mentioned in the online short Dewey's Favorite Quests.
