Portgas D. Rouge

Portgas D. Rouge was Ace's mother, Gol D. Roger's 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 initial D in her name.
 * So far, she is the only D to both cry and smile at their death.
 * She also is the only D to never have displayed super-human strength (although she was able to hold Ace in her womb for 20 months, which Sengoku believed to have been sheer will power).
