I know, except the part about back to Detroit. I recently dug up my old G.I. Joe Marvel issue with the trio origin and also had it in the cheap iTunes collection. What I found out from the collection was one of the Crimson Guards was in that Vietnam ambush battle and left for dead, but after crossing paths with Snake Eyes, etc. years later, became a good guy family man with his assigned family where he was assigned to replace the dad of the family.Storm Shadow is Japanese. He, Snake Eyes, and Stalker were in the same unit during Vietnam. After the war Stalker went back to Detroit(?) to help out in his old 'hood and Tommy Arishikage (Storm Shadow) invited Snake Eyes back to his family's dojo back in Japan to help him train/heal.
That's why the have the same family clan tattoo on their right forearms.
I think...
Also Arashikage literally means storm shadow in Japanese. Curious if you learned any Japanese during your time there. I'm always impressed when I see foreign sumo wrestlers fluent in Japanese.
