Even if they set only one round in the game options, they still get one round with True Ogre. After winning the first round against Ogre, he transforms into True Ogre. Very much like Tekken 2, but there are some differences. The player faces random opponents on the first 8 stages, then Heihachi Mishima on stage 9 (with the exception of Heihachi, who faces Jin Kazama instead of himself), and Ogre on stage 10.

Devil and Angel face Jun Kazama on stage 9 and each other on stage 10.

Kazuya faces Heihachi Mishima on stage 9, instead of himself.

Roger and Alex will face Kuma on stage 4 if the player wins the final round of stage 3 with less than 5% health remaining (as above) and will face each other as sub-bosses on stage 8.

To unlock Roger (and Alex, his palette swap), the player must win Stage 3 with less than 5% of the health bar left, i.e. Roger, Kazuya's sub-boss, will not be unlocked when Arcade mode is defeated with Kazuya (since this unlocks Devil/Angel).There are some exceptions to the statements mentioned above: Kazuya can be unlocked by clearing Arcade with one of the sub-bosses after all of them have become playable, and Devil/ Angel by clearing Arcade mode with Kazuya. After clearing this mode, the ending is shown and the player's fighter's sub-boss is unlocked. Stage 8 is against the character's sub-boss, stage 9 is against Kazuya Mishima, and stage 10 is against Devil after Kazuya transforms into him. The first seven stages are randomly selected fights against seven of the other initially available characters, while the last three stages are set. The player fights ten stages, as opposed to nine in the first Tekken game. Only the eight default characters have ending videos completing the game with a sub-boss or Heihachi will go straight to the game's staff roll.

When playing the game as Heihachi, the player will face all the sub-bosses, followed by Kazuya Mishima in his Devil outfit as the boss. Clearing the game without using continues unlocks Heihachi.

After defeating Heihachi, the character's ending plays and their sub-boss is unlocked for play. The first seven are against random characters, the eighth is against the character's sub-boss, and the ninth is against Heihachi Mishima, the 'boss' of the game. In the first installment of the series, the player fights through nine stages.
