Diego is the leading character of the trio. Initially, the saber-tooth belonged to Soto’s pack, and had to retrieve a live baby from his leader to quench Soto’s thirst for revenge to avenge his family. Unfortunately for our favourite smilodon, the woman holding the baby did the ultimate sacrifice by jumping from the top of the waterfall to let precious offspring. The baby was then recovered by a Manfred and Sid, which they both decided to adopt. Not having much choice, joined Diego the group to guide them through the mountain.

Still, Diego was fixed on his ideas, going on Manny and Sid’s journey to return the baby to his tribe while still plotting on completing the mission he was assigned by Soto. However, throughout the journey, the sabre-toothed tiger starts reviewing reviewing his position and begins to feel guilty, focusing more on his new companions. Thus Diego finally decided to turn against his original clan to join this new pack.

This choice was a good choice because the tiger was able to learn to control his fear of the water with the help of Sid in the second movie. However, to give up hunting is dangerous for a smilodon, and Diego started worrying on what to do when Manny started a new family with Ellie. Not only that, but he had been losing his touch, because his breathing was diminished during his hunts. Leaving the group, Diego did not consider returning to these former prey he had spent so much time with. But when Sid turns out to be in danger, the tiger does not hesitate and reunites with the gang to rescue Sid! Initially very musty, Diego opens gradually as the films progress, so it will eventually fall in love in the fourth film…

Diego is known to be cynical and scathing in his lines with a deep voice, he knows how to keep calm in all circumstances, and can make the right decisions.
