"You made me wait quite a while. You seek power, correct? Then let us form a pact. Since your name has been disgraced already, why not hoist the flag and wreak havoc...? The "other you" who exists within desires it thus...I am thou, thou art I...There is no turning back...The skull of rebellion is your flag henceforth!"

—Persona 5 compendium
William Kidd was a Scottish pirate and privateer in the 17th century. His early career was spent in the Carribean, where he aided the besieged English colony of Nevis by ransacking the attacking French. In recognition of his actions, the King of England awarded him a letter of marque, granting him legal protection so long as he remained loyal. However, during a voyage to the Indian Ocean, his crew plundered a neutral ship without his knowledge, branding him an outlaw once more. Eventually, he was captured and sent to London, where he was tried and executed.
As time went on, Kidd's reputation as a pirate became the stuff of legends and folklore, with many tall tales being told about his adventures, most famously involving him burying plundered treasure to protect it from his greedy associates.
Captain Kidd is the Initial Persona of Ryuji Sakamoto. Shujin Academy Library has a book based on him called "Pirate Legend" that boosts guts. Captain Kidd specialiazes in Physical and Electricity Attacks, allowing him to follow up strikes at an enemy's weakness with punishing Physical attacks, especially if Charge is used prior.
In an early concept of Captain Kidd, he appeared somewhat restrained in what appears to be a gibbet cage, which is a reference to William Kidd's body being gibbeted for three years after being hanged for piracy.
