Lieutenant Lesaro (also known as Mr. Lesaro) is the secondary antagonist of the 2017 live action film Pirates of the Caribbean: Dead Men Tell No Tales. He is Capitán Armando Salazar's right-hand man and personal assistant, and his own most loyal crewman.
Lesaro was a lieutenant of the Spanish Royal Navy that served on the Silent Mary under the command of King Ferdinand VI. Fiercely loyal to his captain, Lesaro followed Salazar on his numerous pirate-hunting expeditions; even after a battle against ten pirate ships, he informed his captain of the surrender of the pirates, but Salazar ordered their deaths, which Lesaro reluctantly obliged to.
It wasn't until they went sailing after a young pirate named Jack Sparrow, as Salazar doesn't want to miss out a single pirate. Salazar and his crew followed Jack to the mysterious waters of the Devil's Triangle, where their ship was mangled by rocks within the Devil's Triangle. This causes the powder stored within the ship to ignite and consume the ship with an unrelenting fire, seemingly killing Salazar, Lesaro, and the entire crew.
However, it turns out that the crew's bodies begun to sink to the bottom of the sea and were suddenly struck by streaks of eerie red light, resurrecting them as the undead by the mysterious supernatural powers of the Triangle, where they were currently trapped. Unable to escape from the Triangle, Salazar, Lesaro, and his undead crew of spent over 20 years in a cave, plotting their revenge on Jack Sparrow.
Escape from the Devil's Triangle
25 years after their imprisonment in the Devil's Triangle, Salazar and his crew spotted the Monarch, a British Royal Navy warship, entering their cave. As the Monarch came to a halt, Salazar, Lesaro, and the crew ran across the water, boarded the ship and launched a surprise attack. Due to their ghostly powers, they easily slaughtered all the British soldiers onboard.
With the battle effectively over, Salazar walked below deck finding a single young sailor named Henry Turner locked in the brig. Salazar allows Henry to escape to find Sparrow and give him a message about death coming straight for him.
Return for Revenge
Salazar, Lesaro, and the crew managed to escape from the Devil's Triangle, steering the Silent Mary into the open sea for the first time in years. Though the ship was now nothing but a wreck, she was kept afloat due to the magic. As such Lesaro aids Salazar in his next plan to find the legendary Trident of Poseidon, the mythical artifact which would give them and their crew absolute control over the seas so they could continue their mission and kill all the pirates in the world, starting with Jack Sparrow.
Freed from the Devil's Triangle, Lesaro helps out in the crew's anti-piracy campaign by encountering a pirate fleet commanded by Hector Barbossa, the Pirate Lord of the Caspian Sea. Without hesitation, they quickly attacked and destroyed three of its ships, the Jonty Lark, the Golden Pheasant, and the Rising Phoenix.
Though the rest of the fleet managed to escape, the message the undead Spaniards sent was clear - the dead have taken command of the sea. Some time later, the Silent Mary encountered the Queen Anne's Revenge, Barbossa's flagship. As the Silent Mary approached the Revenge, Salazar and his crew used their magical powers to bend the bow of their ship backwards, opening the ship's hull like the jaws of a giant beast right in front of the pirate vessel, leaving the pirate crew stunned and unable to react. Salazar then leaped on board the Revenge, landing behind Barbossa and blackmailing the latter into helping him find the Trident and kill Jack at once.
Final Battle and Death
Later on, Salazar and his crew spot Jack on another ship called the Dying Gull and attempt to attack. However, Jack, along with Henry Turner and Carina Smyth (who is later revealed to be be Barbossa's daughter), escape on a lifeboat to a small island. Salazar, Lesaro, and the men follow the three to the island, but they soon realize that they can't enter on dry land, as evidenced when one of the crewmembers instantly turned into dust after setting foot on dry sand. Despite this, Barbossa manages to catch up to Jack and the others, but decides to help them as he wants to use the Trident to destroy Salazar and his men for good.
Using an old map (which Carina found) that marks the location of the Trident, Jack and his gang sail across into a small island with the Black Pearl, where they finally spot the Trident. However, this caused the ocean to create a huge rift while Salazar and his crew have already followed them to it, resulting a battle between Jack's crew and Salazar's crew. However, Henry destroys the Trident to end all curses that roam the seas, causing Salazar and his men (including Lesaro) to turn back into normal people. This also causes the ocean rift to finally close, as Barbossa reels in Jack, Henry, and Carina to safety by using the Black Pearl's anchor, Salazar and his crew make a run for it, but only Salazar and two other crewmen who followed him closely manage to cling to it, as the rest of the other crew, including Lesaro, beg for their captain's help, but blinded by vengeance, Salazar forgets them as the ocean closes, leaving Lesaro and the rest of the crew to drown to their deaths.
Lesaro is an extremely loyal and steadfast individual for Salazar, yet he knows that Salazar has become obsessed with the idea of revenge, and he knows that obsession may lead to their undoing. Despite the fact he is loyal to Salazar, he does not show the same cruel and ruthless personality as his Captain; in fact, Lesaro shows concern at certain times, especially when Salazar is about to possess Henry in order to step on land. Lesaro tells him he does not think it is a good idea because once he has possessed the living, his spirit will be trapped in that body forever. He is also slightly empathetic and vicarious for the pirates who are in the water, but after given the command by his Captain, Lesaro reluctantly followed his orders and proceeded with carrying out the order, causing the deaths of the pleading pirates.
Lesaro is the only member of the crew to have an eyepatch.
