How did the prince of Persia get the badge?

The game arrangement is needed, because the second generation does not have the dagger of the sand of time, so it must be changed to someone else. The breastplate is such a function, and the other is the function of adding blood. Because of the return of the third generation dagger, the breastplate is certainly unnecessary. In fact, in the opening animation of 2, when the enemy of Sha Dao approached on the ship at that time, the breastplate had an induction glow, suggesting that the breastplate was related to Sha Dao at that time.
