That's a great question! Tigers and komodo dragons are both fierce predators, but they don't naturally live in the same areas of the world. Although they are both found in the island chain nation of Sumatra, tigers and komodo dragons don't live on the same islands. Since they never meet in nature, they're not enemies of each other. If tigers and komodo dragons were forced to be together (say, in the same cage in the zoo) they might fight or simply ignore each other, as species that are naturally unfamiliar with each other sometimes do (even if they could be at risk from each other).
