I have been making a flash animation that compiles information on all known Lion King characters. Here's what I wrote for Uru's page in my flash animation:
[quote]Not much is known at all about Uru, mother of Mufasa and Scar. Not even what she looks like. She is never featured, only mentioned. Fans suggest she would have a coat similar to Scar, as to allow that darker coat gene to pass from Uru to Scar. Also suggested is that she would have had green and yellow eyes.
In A Tale Of Two Brothers, it is mentioned that Uru went to search for water, because the Pride Lands were suffering a terrible drought. Other than that, not much is known about Uru.
To the right is a beautiful drawing by Balaa. It is titled, "I Remember". Balaa describes the piece: "you will always be king of my heart."- There was a time when even the darkest of souls had light and laughter, when time hardly mattered and the future was still so far away. Monsters are not always born, they are not motherless bastard sons of the devil. No the most hideous of beasts are made by the moments in their lives when time stood still. These are the beasts that are prisoners of their own misfortune.. What is it in their last moments that they remember when time stands still once more.

And attached is the image by Balaa. As for the flash animation: I should have it finished by the end of 2008.
