This is a pretty close fight between two enforcers of the law. Judge Dredd has his cool hoverbike, which is a powerful weapon for justice and he can use it to fire away at Robocop from a distance. To counter this, Robocop has an energy weapon of his own and he does have better physical stats than Dredd. In the end, his array of weapons ranging from an arm cannon to his missiles should grant Robocop victory. Robocop wins.
