Suggested by Anonymous Jaco is a decent police officer and can actually put up a decent fight once he gets serious. That being said, he isn’t quite good enough to fend off Yami Yugi’s entire army. That will be way too much for him and I wonder if his gun could even injure the strongest monsters like Obelisk. I personally doubt it and that’s a big blow to Jaco’s chances. Yami Yugi wins.
