In the original film, the captain's hooks are briefly seen after Mr. Smee informs Hook that Pan has banished Tinker Bell. This shocking news gives Hook an idea, so he orders Smee to retrieve his case of hooks (which Smee calls his "Sunday set") before he sends him to capture Tinker Bell. The Captain was still seen wearing his golden hook, as he uses Tinker Bell's jealousy of Wendy to learn the whereabouts of Peter's hideout.
The captain's hooks play a larger role in the Disney Junior spin-off no longer just limited to a mere case, but an entire cabinet of various hooks at the captain's disposal to help him collect as much treasure as possible and even plunder treasure from Jake and his crew. Some of the hooks include a Whirly-Hook to give the captain flight, a plunger hook to grasp treasure, and even a butterfly net hook.
In the episode "Captain Hook's Hooks" Captain Hook notices that his prized collection of hooks are filthy. He orders Sharky and Bones to clean them but while they were cleaning, the Octopus creeps aboard the Jolly Roger and steals eight of Captain Hook's hooks from Sharky and Bones before fleeing back into the Never Sea. Knowing they'll have to walk the plank if the captain finds out Sharky and Bones to pursue the sneaky cephalopod to Neverland with the help of Jake and his crew to retrieve the eight stolen hooks. They are retrieved and the hooks are resorted. However, in the mix of getting them back, the hooks are even more filthy.
In the episode "Hook's Hookity-Hook!" the Captain get fed up with switching between his hooks so he invents an all in one Swiss army hook called the "Hookity-Hook" so he'll always have every hook in his collection on hand. But it becomes too hard for Hook to control, forcing him to revert to many individual hooks once more.
When Beatrice Le Beak and her pet falcon Fast Claw are held captive by Captain Hook and his crew at the end of the episode "Jake and Sneaky Le Beak!" and forced to walk the plank, but Beatrice and Fast Claw evade capture and a watery fate with Captain Hook's Whirly-Hook.
In the episode "Pirate Pals!" Beatrice is captured yet again by the combined forces of Captain Hook and Jake's crew. Hook plans on leaving Beatrice Le Beak stranded on a deserted island, but before Hook could put his plan into motion Beatrice Le Beak makes her escape yet again from Hook's Whirly-Hook.
The Hook of Killian Jones is a replacement of the character's left hand when Rumplestiltskin chops off Jones' hand. Killian Jones' notoriety of having a hooked hand earns him the nickname "Hook." He finds a way to travel to Storybrooke and get revenge on Rumplestiltskin, now known as Mr. Gold. After Hook is being hospitalized for severely fractured ribs, his hook is taken away and kept in the sheriff's office, but he eventually steals it back. Using a type of poison, he coats his hook and tracks down Mr. Gold in New York where he stabs him. When Killian blackmailed Mr. Gold into reattaching his lost hand, Emma jokingly asked if she was supposed to call him "Captain Hand". However, the hand belonged to his old self, and was causing Killian to relapse back into that person; in exchange for a favor to Mr. Gold, Killian had his hook once more take the place of his hand.
Emma once pointed out that Killian looks for any opportunity to use his hook. If he needs to appear harmless in the Land Without Magic, Killain swaps the hook for a fake hand.
