A hybrid is part Dragonoid and part Tigeroid. In order to keep peace and balance in Suhn, the Dragonoids and the Tigeroids were supposed to be kept seperate. Anyone who broke this law was severely punished. The only known hybrid currently in the show is Rai, due to the fact that he could use Dragonoid cards. Hybrids are likely to be more powerful than the purebloods due to this.
