This hybrid dragon was created as a mating of a red and black dragon. Typically, these dragon types don't make, but in this rare case, a male red dragon was able to dominate a female black dragon long enough to produce these unique offspring.
In my campaign, the high-level players found several of these "tiger" dragons in a lair where they were expecting to find a very old black dragon. The black dragon had been killed years ago, but its offspring continued to grow in an uninhabited swamp until they were discovered by adventurers looking for a dragon's horde.
