Jinx studied and competed in three forms of martial arts from the time she was seven until she graduated from Bryn Mawr. Upon arriving in Japan for a vacation, she discovered that her family had been ninjas for generations and she was officially initiated into the clan. Jinx was recruited for the Joe team by Snake-Eyes. "Don't underestimate Jinx. She has been to the Secret Mountain and studied the Seven Silent Forms with the Blind Master. She has the Eye That Pierces, the Iron Hand and the Heart That Waits. She can see through your deception, batter aside your defenses and dazzle you with the strength of her will."
Jinx is a G.I. Joe team operative in the A Real American Hero line. First released as a Hasbro carded action figure in 1987, with 1 distinct figure version produced across the 1982 to 1994 vintage run.
Jinx did not appear by name in the Sunbow or DiC cartoon series synopses. Original Hasbro file-card lore and Marvel ARAH comics appearances are the primary characterization sources.
