Most Chinese readers know
艾斯 as Portgas D. Ace (
波特卡斯·D·
艾斯) from Eiichiro Oda's One Piece (《
海贼王》/《
航海王》) — Monkey D. Luffy's adoptive older brother and a fan-favorite whose death at Marineford is one of the manga's most discussed moments. The character's name is the English word "ace" (as in playing cards), and
艾斯 is the standard Mandarin rendering of that one-syllable English name.
