The Tanden Engine is a powerful device developed by Shadaloo and S.I.N. to be used in the "puppets" that are spare bodies for Bison should anything happen to his body, including Seth. The device takes the form of a large sphere adorned with the yin-yang design. It is located in the abdomen of these "puppets", and grants them a remarkable amount of power. It appears to harness both positive and negative energy, as evidenced by the colored energy that emanates from Seth's hands when he uses it.
Special Attacks using the Tanden EngineEdit
A move with the same name, the Tanden Engine, is one of Seth's special attacks. Executed by performing a quarter-circle backward motion and pressing punch, Seth brings his hands together in front of his abdomen and generates a miniature black hole which sucks the opponent toward Seth. The attack does not deal damage and is intended to put the opponent off balance, creating an opening to initiate a damaging attack or combo. Its effective range (how close the opponent needs to be for the "gravity" to affect them) depends on the punch button used. Notably, the EX Special version requires two segments of the Super Gauge instead of the usual requirement of just one segment. The EX version is considered far more useful than the standard version.
The Tanden Storm is Seth's Super Combo. Executed by performing two quarter-cirlces forward and pressing punch, Seth says "Let's take this to the next level!" and swirls his hands around in front of himself, generating a miniature black hole which sucks the opponent toward Seth, similar to the Tanden Engine special attack, and finishes it off by blowing the opponent away if the move properly connects. Its effective range (how close the opponent needs to be for the "gravity" to affect them) depends on the punch button used. However, unlike the Tanden Engine, the black hole is larger and does deal damage to the opponent when they come into contact with it while not blocking. The attack lands a maximum of 21 hits (attainable by performing the move at point blank range).
The Tanden Stream is Seth's first Ultra Combo. At first, Seth says "See what I'm really made of!" and swirls his hands around, then releases an invisible projectile. If the projectile hits the opponent, they are pushed backward. If the opponent did not block, they are then sucked into a vortex emanating from the Tanden Engine in Seth's abdomen as Seth says "Become a part of me!". Once inside the Tanden Engine, the opponent is swirled around, suffering damage as Seth laughs. He then fires the opponent out and they hit the screen face-first while saying "It's over". Despite the attack taking a longer-than-average amount of time, it does surprisingly little damage, unless Seth is controlled by the CPU as a final boss in Arcade Mode.
The Tanden Typhoon is Seth's second Ultra Combo. Seth starts by saying "Behold the glory that is the Tanden Engine". He then bends backwards with his face towards the opponent and releases a gigantic tornado out of the Tanden Engine, which is aimed diagonally upwards across the screen. The attack itself is best used as an anti-air, as it can catch people trying to jump in. Just like his 1st Ultra, this move does not inflict much damage.
