Boss Description
Troy Calypso is a ‘Boss’ in Borderlands 3. He is also one of the two main antagonists in the game. Troy is the only male Siren to date. He and his sister, Tyreen, were conjoined twins at birth. That’s probably why he has 1 mechanical arm. This is also reflected in his right Siren wing being smaller.
Troy Calypso is located in The Great Vault on the planet Pandora. The fast travel station will drop you on the dig site in front of the battle arena next to 2 vending machines. 
You can farm Troy Calypso for these legendary weapons as it is the dedicated loot source for these items. Troy Calypso has a 30% legendary drop chance.
