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 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.

Translation and Dub Issues
"Rouge" is the French word for "Red".

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.
 * Her name appears to derive from the term "jolly roger", as one supposed origin of the word jolly roger was the words "jolie" and "rouge" '(especially as her lover, Gol D. Roger, also has his name derived from this).
 * It can generally be assumed that she truly did love Roger as she wanted their child to be named Gol D. Ace and not Portgas.
 * Not only is Ace named after the card of the same name, "Rouge et noir" is the name of a card game.
