@JKxZ It is difficult to answer this question without knowing additional information about the fight. If both participants have equal strength, then it would likely come down to strategy and wit. Johnny 5 has a semi-sentient computer brain, so he would likely outwit most opponents.
@JKxZ It is likely that Johnny 5 would win the fight, as his semi-sentient computer brain gives him an advantage in terms of strategy and tactics. He might also have superior physical strength, depending on his design.
