Sam Winchester

Sam has shaggy brown hair that grows longer and smoother in later seasons; he had a fringe as a child as well as in the first two seasons. Over the course of the show, he grew the fringe out. His eye color seems to change; sometimes they appear light green, sometimes they appear brown, etc. He is noted by other characters to be handsome. Sam is tall, standing at 6’5” —— making him taller than his older brother. Sam has a muscular build with broad shoulders and a muscular chest. This is especially ironic considering that he used to be teased for being short and wiry as a teenager. Like Dean, Sam often wears multiple layers of clothing (namely plaid shirts) as well as jeans and boots. In Season 8 of the series, Sam, who is known for always having a clean shaved face, has been sporting some facial stubble similar to Dean. In season 14, Sam grew a beard in the three weeks that Dean was possessed by Michael, mainly due to running himself ragged while hunting for leads. He later shaves it off in Mint Condition, after Dean made fun of him.

Sometime before Jus In Bello, Sam got a tattoo on his chest of the anti-possession symbol to protect himself from demons. He kept it until Road Trip when Castiel removed it so Crowley could go inside Sam and help him expel Gadreel. He got it restored at some point off-screen as it is seen again in later seasons.Sam possesses a dual nature. He can be unusually kind, empathetic, intelligent and independent. But he can also be coldly pragmatic, cruel, vengeful, arrogant, and proud. Sam tends to be driven by feelings of anger and vengeance. It is only through constant, deliberate choice that Sam develops his better qualities and rejects his darker side.
