Killian Jones

Killian Jones, better known as Captain Hook or simply Hook (portrayed by Colin O'Donoghue) is one of the main characters of Once Upon a Time. He is a determined pirate captain who was unfortunate to humiliate and anger the feared Rumplestiltskin, who ripped out of his beloved Milah and cut off Killian's hand. This led to Killian seeking revenge on Rumplestiltskin, who currently resides in Storybrooke. However, he forms an alliance of sorts with Emma Swan.
