This remaster of C-chan's chibi fanwork of Mac OSX Leopard-tan (originally created by Aurora) is so radically different from the original, it might as well be a new drawing. Aside from modernizing her appearance entirely (being more faithful to the Aurora's original and updated renditions, and incorporating elements from Bella's later designs), her face and pose have been enhanced to make her appearance more dynamic than the relatively stale original. A random background has also been added, although it's not intended to be a true light source.

At the time of its creation, this was the first depiction of a Leopard-tan C-chan had known at the time, so he drew the original as a gift to Aurora (and for the purpose of supplying a Wiki icon for the now-defunct List of OS-tan Characters article on Wikipedia). Later, a pink-haired version was created elsewhere by Esu, followed by a younger magical girl Leopard-tan created by an anonymous Japanese artist.

Given our custom canon depicts her as a time-traveling genius, all three versions are valid in our canon as differently-aged versions of the same character, who often converge during the same time period to interact with one another (in defiance of any potential universe-destroying time paradox).
