How Tetsujin joined the Tourney
Given that Bowser, Ganondorf, and Mewtwo are not giving up, it is assumed that Tetsujin arose to stop them. Seeing as there are three evil forces to be stopped, this may explain why he was also "activated".

- Like in Tekken Revolution, Tetsujin is a rare opponent in the game's Classic Mode, appearing before the final stage randomly along with Mokujin and, if unlocked, Kinjin. To alert the player that one of those three guys are going to appear, the announcer will say "Warning! A Fierce Opponent has appeared before you!" after the Race to the Finish bonus stage. They'll be more likely to appear on the Hard, Very Hard, and Extremely Hard difficulty levels. If any of these guys are defeated, the player will receive a huge amount of Smash Coins to be used in the Smash Store to buy parts for various sections in the game, ranging from 100 coins for defeating Mokujin, 500 coins for defeating Tetsujin, and 1,000 coins for defeating Kinjin. You'll also get the Mokujin KO bonus if you defeat Mokujin, which yields 10,000 bonus points, the Tetsujin KO bonus if you defeat Tetsujin, which yields 100,000 bonus points, and the Kinjin KO bonus if you defeat Kinjin, which yields 1,000,000 bonus points. In Tourney 2, Female Mokujin is also included in these hidden opponents.
- Tetsujin is the only training dummy from the Tekken universe who doesn't get angry at Ulala when she fights any of them. Mokujin gets angry at her for calling him a tree, and Kinjin gets angry at her for calling him "King Gold".
- In Tourney 2, Tetsujin thinks the Female Mokujin (from his brother's Tekken 3 ending) is his sister.
- The rival of Tetsujin is Jennifer Bennett. Tetsujin gets a second rival in the sequel, and that character is also Jennifer.
