Chevalle is a vain pirate wearing elegant clothing.
Hailing from Marseilles, the trade capital of France, Chevalle was the pirate Lord of the Mediterranean Sea. He used a golden stick and also wore a silver ring on his left hand. He also wore a purple coat and a blue waistcoat, alongside a tricorn hat he wears on his head.
In a plan to consult the pirate lords of the Brethren Court at Shipwreck Cove to fight against Davy Jones working for Lord Cutler Beckett, Chevalle and the rest of the pirate lords are present with Jack Sparrow and his crew attending under command by Hector Barbossa where all the pirate lords hand their pieces of eight to bind Calypso in a plan to fight Davy Jones under command of Lord Cutler Beckett. During a plan to fight against Davy Jones and free Calypso, Chevalle and the other pirate lords refuse to listen and fight each other in a brawl, believing Calypso is a threat to the Brethren Court. Barbossa, however, stops the fight, clarifying that it was the First Court who imprisoned Calypso, planning to release her. Jack Sparrow takes part in a speech devising a plan to fight against the EITC's forces while Barbossa summons Captain Teague who later arrives to deal with the plan.
As Captain Teague arrives, he shows Jack's crew and the Brethren Court the Codex to which all the pirate lords vote for themselves and as Elizabeth plans to fight against the EITC, Chevalle and the other pirate lords accept Elizabeth's request in a plan to fight against the EITC. Later when Elizabeth commands all the pirates to raise their flags to prepare for battle, Chevalle is present with the pirate lords who also raise their flags to prepare to fight against Davy Jones and the EITC under Elizabeth's command. After Davy Jones falls to his death during battle at the maelstrom and Lord Cutler Beckett is defeated for good, Chevalle and the other pirate lords celebrate their freedom from the EITC, alongside Tai Huang and his men and the crew of the Black Pearl in victory.
In the opening cavern sequence of this ride, the skeletal corpses of the Brethren Court members can be seen sitting at a table, Chevalle being one of them. It is unknown how they died or what they were doing on Treasure Cove which lead to their apparent deaths.
- Chevalle has a striking resemblance to Captain Hook, a villain from the Disney film, Peter Pan. He also resembles René Rottingham, a minor character from the novel, The Curse of Monkey Island.
- Chevalle's name is derived from "Cheval", the French word for "horse".
