Back in the early G.I. Joe days, when Snake Eyes was still a commando and not a ninja, my go to guy for martial arts adventures was Torpedo.
After all, it's right there in his filecard: "Attained black belts in three martial arts by age 19 (Wu-Shu, Kenpo, and Go-Ju-Ryu)."
No real modifications necessary for this one. Just straight paint job on the Reaper Mini Navy Seal Diver (50058).
Now, I just need to find a good mini for a Cobra Eel.
