Pericles is an anthropomorphic dog.
A Greek fisherman and diver named after the historical figure, Pericles found the immobile Colossus of Rhodes at the bottom of the sea while diving one day. He took away one of the buttons on its armor-plate as proof of his discovery, not knowing that he'd removed the one piece of the giant automaton's mechanism that had been jamming him for so many years. The Colossus, freed, resumed wandering the bottom of the sea aimlessly, having reverted to its mission of "protecting Rhodes". Pericles later tried to sell the button to archeologist Eurasia Toft, putting her on the trail of the lost Colossus.
Behind the scenes
Pericles was featured in the 2005 story Shadow of the Colossus.
