Storm Shadow is a fictional character from the G.I. Joe comics series and television shows. The character is best known for his history with fellow ninja Snake-Eyes. Throughout their history, the duo have been everything to one another from the bitterest of enemies, to the most loyal of friends (and blood brothers) who would fight and die for one another.
Storm Shadow's real name is Thomas S. Arashikage () (Arashi = "Storm" and kage = "shadow" in Japanese). Best known as the Cobra Commander's ninja bodyguard and assassin at times, he is the only member of the team to change sides several times, conflicted in loyalties between Cobra, G.I. Joe, and his long relationship with his sword-brother Snake-Eyes.
He usually wears a white uniform and mask. When out of his uniform, he is shown to be Japanese-American, with black hair and dark eyes. In 2007, the character's creator Larry Hama revealed an alternate name for the character, Tomisaburo Arashikage, in the solo series Storm Shadow.
Storm Shadow is one of the few characters from the G.I. Joe: A Real American Hero line that has been released as both a member of Cobra and a member of G.I. Joe. He first appeared in 1984 as a member of Cobra, but his second figure, released in 1988, was changed to a member of G.I. Joe. His loyalties remained with G.I. Joe until his 2000 figure was released again as a Cobra agent.
Since then, he has remained a member of Cobra. He is most often paired with his Sword Brother, Snake-Eyes in multi or comic packs. He has had 26 different 3 and 3/4 inch figures released before the beginning of the 25th Anniversary line.
He has been released two times (once as a mail away figure and once in a comic pack) unmasked and revealed to be Tommy Arashikage.
