Duck family (Disney)
Della made her first animated appearance in "DuckTales" (2017), with her son Dewey discovering she was previously a companion of Scrooge and Donald's in their adventures and starts investigating the cause of her disappearance along with Webby Vanderquack and later Huey and Louie. They subsequently discover that Scrooge has gone to great lengths to conceal information about her. It is eventually revealed shortly before the triplets hatched, Della stole "The Spear of Selene", a spacecraft constructed by Scrooge as a gift, to give it an early test run. However, she got caught in a cosmic storm and was lost in space. Scrooge spent a large portion of his fortune looking for her, but was ultimately unsuccessful. Blaming Scrooge for her disappearance, Donald cut all ties with him and raised Della's children on his own. Della is later shown to be alive, living on the moon in the remains of her crashed spacecraft and unable to contact Earth.
