Mama Hook

Mama Hook is a character from the Peter Pan saga. She is the mother of the villainous Captain Hook and was presumed deceased until her appearance in Jake and the Never Land Pirates.

Return to Never Land
In the film, Captain Hook's treasure was taken by Peter Pan as a prank. To get is back, Hook needed a way to ally himself with the film's protagonist Jane who would be able to get it for him. In order to do so, he claimed he wanted the treasure so that he can return home to his mother. He pulls out a locket with a portrait of her.

Jake and the Never Land Pirates
In "Jake's Starfish Search" Hook and Smee were putting up a portrait of Mama Hook and, judging by the conversation, she has passed away. This was the thought, until she was confirmed to appear in an upcoming episode of Season 2: Mama Hook Knows Best. Here, it is revealed that Mama Hook was once queen of the NeverSea and a magnificent pirate. She was able to find all and any treasure she dared to. She acted as a mentor to her son, Hook, who was rather bumbling during his years as a young seapup.

Trivia

 * In Return to Never Land, Mama Hook was seen with a hook on each arm but in Jake and the Never Land Pirates she doesn't have hooks at all, instead she has hands.
