Percy Jackson and the Olympians: Legends

Tyson is two meters tall (though he can grow up to 30 feet tall at will), and very broad-shouldered. He has very messy brown hair and one large brown eye, but he appears to have two because of the Mist in the mortal world and in Poseidon's forges. He is known for not brushing his teeth.

In spite of his naiveté and seeming density, Tyson is smarter than he seems and very determined. Tyson cares a great deal about his friends and is willing to risk his life for them if necessary. He shows a strong love for pegasi and hippocampi (which he calls "chicken ponies" and "fish ponies" respectively), though the former are nervous around him. However, Tyson is terrified of Grover because the "itchy goat fur" makes him sneeze, but as he got over it to maintain their friendship it is possible that he has gotten over his fear of Satyrs completely. When he rescues Reyna, Nico and Coach Hedge, he comments on Coach Hedge's "itchy goat fur" but displays no fear of him and even helps him back to camp, indicating that he has overcome his fear of satyrs completely. Furthermore, Tyson is very much terrified of everything related to death, such as the skeleton warriors aboard Clarisse's ship and initially Nico.

After the great battles and adventures, Tyson dedicated himself to honing his skills as a blacksmith. His incredible craftsmanship became renowned, with weapons and armor forged by him being sought after by demigods and gods alike. Tyson also took on the role of protector for younger demigods, guiding them through their early years at camp with a gentle yet powerful hand. However, nowadays, Tyson runs the Cyclops Book store alongside his girlfriend, Ella.
