Imagine if Po never did became the dragon warrior, which one of the furious five would become the dragon warrior instead? I would have to go with Tigress cause if you notice, Master Shifu did say that Oogway was about to point at her until Po got in her way and it's not so hard to miss that she was secretly jealous of Po being named the dragon warrior instead of her. So who would you pick that would make a good dragon warrior?
