Percy Jackson and the Olympians: Legends

Calypso was described to have cinnamon-smelling caramel hair that was braided over one shoulder, dark almond-shaped eyes, and a face that appeared to be timeless. According to Percy, it was difficult to tell whether she was 15 or 16 due to her timeless features, but he found her to be "twice as brilliant" as the stars, and far more beautiful than even Aphrodite herself, for she seemed more natural. In The Odyssey, Calypso was described to be a "goddess of strange beauty". Aphrodite's husband, Hephaestus, acknowledged Calypso's beauty, as shown by his compliment of her. Calypso made a pair of jeans and a white t-shirt for herself, as it is better suited for manual labor.

Calypso is kindhearted, and caring. She has a warm heart, revealing that even if her father was ruthless to his enemies, she still loves him and has no anger toward the gods despite their actions. Calypso is very down to earth, understanding why the gods decided to trapping her on her island. She shows a level of curiosity, asking Percy about how the world has changed in the time she has been trapped and feels bad that there is a place where flowers cannot grow, like New York City. However, Calypso can be feisty and rebellious. She didn't like the fact that she had to fall in love because the gods wanted to punish her. She was very shy around visitors to her island as anyone that arrives there is someone she would fall in love with, causing her to hide her feelings.

Calypso was a third generation Titaness, a daughter of Atlas. As punishment for her support in the First Titanomachy, she was banished to Ogygia, a remote island where different heroes whom she couldn't help but fall in love with would end up. None of those heroes whom she falls for would ever be able to stay with her. Calypso was rescued by Leo Valdez after the Second Giant War ended. Once she left her island, she gave up Titan-hood and is currently a mortal, but eventually regained her magical powers. Calypso is the girlfriend of Leo Valdez.
