Pura is a tiger, who Coco found as a cub years ago along the Great Wall of China, during an adventure with Crash and Aku-aku, on a quest to defeat Uka-uka, Neo Cortex and N.Tropy.
How I made him-
Well he's not my character. However, I developed him a lot into what he is in the OB series. In the games, he (and Polar) both remain as cubs, forever. But in OB, I made them grow into adults, and then later on... get evolved as they wanted to go into the future with their 'foster parents', Crash and Coco.
Pura is (c) to Activision but this version of him, was made by me.
