Scrooge McDuck and his nephews are sent by a giant twister to the time of Odysseus where they meet King Homer on his ship, and after many dangers in the sea, Scrooge and Homer face Circe but are turned in pigs with her Magic Medallion. Some time later, the nephews arrived in Circe's lair to take her Medallion and destroy it in.

The giant twister appears again and sends Scrooge and his nephews back in their time.

DuckTales (2017)
Ithaquack is an island off the coast of Greece, and was believed to be only a myth. It was the vacation spot for the Greek gods and their Grecian followers until Scrooge McDuck, Donald Duck, and Della Duck arrived. The gods took an interest in the McDucks, with Storkules and Selene befriending Donald and Della, respectively. Scrooge was livening up the place, but he bested Zeus in everything, which led to the god banishing him and driving away any mortal or god that was upset with Scrooge leaving. There appeared to be few gods remaining by the time Scrooge returned, which included Zeus, Storkules, and Selene. Zeus challenged Scrooge to one more competition, which Scrooge intentionally lost so that Zeus would end his vendetta against him and his family.
