Portgas D. Rouge

Portgas D. Rouge was Ace's mother, Gol D. Roger's wife (or at least lover) and the first female to have the initial D to appear.

History
She was pregnant with Ace before Roger died, and fled to Baterilla in South Blue. There she held her pregnancy for 20 months through some unknown method (speculated by Marine Fleet Admiral Sengoku to be sheer willpower) in order to deceive the world of Ace's connection to the Pirate King. The result of holding Ace for so long however led to her death from exhaustion after giving birth.

As a result of this sacrifice to save his life from the World Government, Ace claimed that he owed her a favor, and used Portgas as his own surname.

Trivia

 * She is the only known female with the Will of D.
 * So far she is the only D to both cry and smile at their death.
