Combot is a super combatic android created by Lee Chaolan in Tekken 4. And recently made his return in Tekken Tag Tournament 2.
Combot is a multi general purpose robot created by Lee Chaolan (under the guise of Violet) to enter in the King of Iron Fist Tournament 4. Combot is programmed to do a wide variety of things, from household chores to military action. This design was made to be the ultimate fighting machine and was programmed to learn every fighter's style as it progressed through the tournament. It was also used to increase the chance of Lee gaining the Mishima Zaibatsu if Heihachi were to be defeated by Combot. Unfortunately, the prototype was rushed due to time constraints and a few bugs were left in Combot's data. Because of this, whenever Combot is powered up, he can only utilize one opponent's fighting style at a time.
Combot returns in Tekken Tag Tournament 2 as a console exclusive. He is also the focus of the Fight Lab mode.
In the ending, Combot was slowly walking around the city, once he sees a machine crusher, he is stunned. He watches the machine crush several cars. The Combot's body falls apart, and his eyes flicker and dim. Violet finds him broken and lying on the ground, and holds the remaining head and torso in his arms, looking at him sadly.
