Percy Jackson and the Olympians: Legends

Damasen is twenty feet tall, somewhat short for a giant, albeit slightly taller than the Titan Bob. From the waist up, he is humanoid, with cherry-red skin, a beard and hair the color of rusted iron, bushy eyebrows, and multiple scars on his face (from battling the Maeonian Drakon endless times). His dreadlocks are decorated with tufts of grass, leaves, and swamp flowers. From the waist down, his dragon legs are red and he has claws on his feet. Being a peaceful giant, Damasen does not wear bronze armor, but rather, a shirt stitched together from sheep hides and green-spotted leather. He initially unsettled Annabeth, as he radiated "sorrow and bitterness".

Gaea had wanted Damasen to oppose Ares, meaning he was the anti-Ares, but this backfired because, unlike his brethren, Damasen was born with a very peaceful and gentle personality, as opposed to Ares's warlike, bloodthirsty nature. Shunning Gaea's orders, Damasen chose to live a quiet life in Asia Minor, tending sheep and befriending mortals. Damasen can, however, be very violent, though not without a valid reason. He avenged the death of one of his friends by slaying the Maeonian Drakon, forcing a tree down its neck. After being imprisoned in Tartarus for several centuries, Damasen was overcome with hopelessness, believing that his curse had overtaken him. This did not affect his original personality and hospitality, as shown when he welcomes Percy, Annabeth, and Bob (Iapetus) to his hut. Later, Damasen arrives at the Doors of Death, and is willing to sacrifice his life to help Percy and Annabeth escape from Tartarus.

Damasen was born to oppose Ares/Mars, the God of War. Being Ares' nemesis, Damasen was peaceful and helpful, and spent his life in the mortal world living as a farmer. One day, a drakon appeared in the mortal world and killed one of Damasen's farmer friends. In a rage, Damasen tracked down the drakon and killed it. He was condemned to Tartarus for slaying the drakon, which was ravaging the mortal world. Damasen was introduced to Percy Jackson and Annabeth Chase by Bob after the Titan led them to his home in a swamp in Tartarus. He healed their wounds and provided them with food and other various supplies to continue their quest. Later, when the trio reached the Doors of Death, Tartarus himself appeared, and nearly destroyed them when Damasen arrived, riding his archenemy, the drakon. Damasen battled his father along with the drakon, Bob, and Small Bob, giving Annabeth and Percy their chance to escape.
