Suggested by iKnowledge Shun falls into a similar boat as Dan. His Bakugan pack a punch and will certainly put up a fight, but they’re just outgunned here. Yami Yugi is also able to contribute to the battle quite a bit thanks to his super form from Capsule Monsters while Shun will mainly have to be satisfied with supporting his Bakugan emotionally. It’s certainly an important role nonetheless, but it won’t be enough to change the outcome of the battle. Yami Yugi wins.
