Unidentified mad scientist

The Tankenstein was created by an unidentified mad scientist.

Imprisonment
Sometime after the apocalypse, the mad scientist was imprisoned for conducting dangerous experiments after being shunned by the scientific community for his work in creating "living" tanks.

Creating the Tankenstein
The mad scientist eventually escaped or was released from prison and resumed work on his "living" tank. This tank, named Tankenstein, was built from parts of what he considered the greatest tanks. Villagers of the wasteland eventually learned of his work and raided the mad scientist's garage, but they were too late. The villagers helplessly watched as the mad scientist flipped the last switch and brought the Tankenstein to life.

Personality and traits
The mad scientist was a brilliant engineer who defied the accepted views of other scientists. He had a great distain for the scientists who shunned him, blaming them for the apocalypse. He was not one to give up easily, as he continued working on Tankenstein even after being imprisoned for it.
