I might be stating the obvious here, but using devil Slicer (or even Eager Cleaver) will slay your first Tigrex easily. If you're on Freedom 2 you can create Devil Slicer before Tigrex. If you're on Unite, you can't due to the required Kirin Tails. Strike his head and learn the signs for when he attacks, such as the stamp before the spin or the roar and recoil before the charge. Tigrex hits like a truck, and moves faster.
