Tetsujin is a secret
character in Tekken Tag Tournament who appears to be a metal version of Mokujin.
Literally translated, Tesujin means "iron man". When Tetsujin is hit, metallic noises can be
heard if the player holds "down" before the battle. Tetsujin's Tekken Tag
Tournament ending shows him training a legion of
Mokujins. If the player wins 10 consecutive matches with any character,
Tetsujin will take on a golden appearance.
