This is Sideshow's G.I Joe Storm Shadow based on the comic book series and not the big screen version. I do like the Hot Toys's movie version but the thought of it becoming yellow stopped me from buying. However, for this, everything about it made me purchase this.
Storm Shadow can trace his family history through thirty generations of assassins. He is an 8th degree black belt in several martial arts, and can endure unimaginable amounts of hardship and pain. Storm Shadow moves with blinding speed, can scale sheer walls with bare hands and feet, and is an expert with a long bow, katana, throwing stars and nunchaku sticks. He usually wears a white uniform and mask. When out of his uniform, he is shown to be Japanese, with black hair and dark eyes.
In 2007, the character's creator, Larry Hama, revealed an alternate name for the character, Tomisaburo Arashikage (嵐影富三郎), in the solo series Storm Shadow. His tattoo is a hexagram of the I Ching named 既濟 (jì jì), or "Already Fording".
