Simea is a supporting character who appears in Disney's 2024 animated feature film, Moana 2. She is the youngest daughter of Chief Tui and Sina and the younger sister of Moana.[2][1]
She is 3 years old by the events of the second film.[2]
Since the sequel takes place three years after the events of the previous film, Sina (Moana and Simea's mom) must've become pregnant sometime during the events of the original film (or at least shortly thereafter) while Moana was out voyaging throughout the ocean.
The name Simea means "listen" or "God has heard" in Hebrew.
The concept of Moana having siblings was touched upon during the story development of the first film, as Moana was originally going to be the youngest/only daughter of ten children -- her nine older brothers would've sailed off the island, leaving their sister behind, but Moana would've eventually gone off to rescue them.
