Is the Indominus Rex stronger than the Spinosaurus? From what I figure from all the information when both are fully grown and rested it seems the Indominus Rex would win above 90% of the time unless the Spinosaurus fought the Indominus in water that was too deep to stand in (the Indominus being hyper intelligent would figure to stay out of very deep water).
