Quadro was built by the European Union as a machine to act against the various evils of the world. Unfortunately the project got into the wrong hands and only Quadro and one of the scientists involved was able to escape before corruption. Now these two are tasked to fight against evil for the sake of justice!
Quadro lives in a very secret and isolated base, in order to stop outside influences (since the betrayal he experienced in his passed). His locations is kept really secret. But, he never really stays at his base all the time. He travels the world, and is ready to fight at any moment he is needed.
He will always be there when you need it the most. His four arms offer twice the strength as two arms. He has the knowlege base and thinking skills of the worlds smartest people. He knows how to do the job the fastest in order to move on to other peoples needs. All of this while also being able to improve everytime.
