Princess Nami
Princess Nami in He-Man and the Masters of the Universe (1983), played by Erika Scheimer.
He-Man and Man-At-Arms swam into the cave where she was being kept and He-Man defeated the Coral Creature by causing a cave-in.

He-Man manages to spin a guard rail on the edges of the city fast enough that it destroyed the whirlpool, saving Aquatica.
