Percy Jackson and the Olympians: Legends

Pollux is seen very briefly with his brother and they are both described as "a couple of plump blond boys who looked just like Mr. D." As a result, it can be said that he is not athletically built, much like his brother Castor. In addition, Pollux is not described as being very good-looking, with slightly curly blond hair, violet-colored eyes.

Pollux is level-headed and a good warrior. He is not very close to Percy Jackson, Annabeth, or Grover, but is very brave and protective of his brother, who is his best friend. When he breaks his arm, he was willing to fight with his left hand, though he only practiced with his right, which would have likely been suicide had he gone back in battle.

Pollux is a Greek demigod, a son of Dionysus, and the twin brother of the deceased Castor. Pollux is the only member of his cabin. He fights bravely in battle and calms the other demigods down when they are worried and anxious about the spy among them. He is shown to be a good warrior, even though he doesn't look physically fit. He is also known to have common sense. During the Battle of Manhattan, Pollux broke his arm in battle, and Percy insists he not get back into battle, but doesn't tell him why. He tells Pollux it's a "personal favor." Dionysus specifically requested that Percy keep his son safe, in a vision Percy had, but Percy didn't want to embarrass him by revealing it. This possibly implicates that Dionysus had been watching over his son after the death of Castor, and perhaps Pollux hadn't dealt with Castor's death well.
