During her time with Orochimaru, Anko learned several of his techniques, such as the ability to summon snakes. She was also taught how to use the Twin Snakes Mutual Death Technique (双蛇相殺の術, Sōjasōsai no Jutsu?, Viz "Twin Snakes Kill Each Other", English TV "Twin Snake Sacrifice Jutsu"), which calls forth two snakes from her sleeves to bite the wrists of her and her opponent, killing both via the venom that enters their bloodstream. She attempts to use this ability on Orochimaru when they meet during the Chunin exams, though he is easily able to avoid it and escape.
