STONE (MARVEL COMICS)

'Stone' was the favoured pupil of Stick, the blind former mentor of costumed crime-fighter Daredevil and Elektra Natchios. He is a member of the Chaste and is a highly trained martial artist and assists his sensei against the Hand. Like the other members of the Chaste, Stone is deeply advanced in the art of chi-manipulation. An offshoot of this is his ability to render himself invulnerable to physical harm - but only if he sees it coming.
He has appeared in ''Daredevil'' (vol 1) on various occasions; once where he is told to take Daredevil and Black Widow to safety whilst his comrades Shaft and Stick sacrificed themselves. Later he famously assisted Daredevil as the Hand attempted to resurrect Elektra as their agent. He managed to restore Elektra and cleanse her soul using Matt's love for her and a portion of his own life force. This weakened him and he was believed dead. Later, Daredevil found him still battling the Hand, in the miniseries "Daredevil: Ninja".
In the Elektra movie, Stone is a member of the Hand, played by Bob Sapp. Elektra kills Stone by having him break down a large tree and making sure it falls on him, crushing him.
In the Ultimate Marvel Universe, Stone is the female sensei of Elektra Natchios, having taught Elektra since she (Natchios) was a young girl.
