Trivia

 * Ushar's name is a shortened form of Tushar, meaning "cold, frost, snow" in Sanskrit. This reflects him being a rare white lion.
 * Ushar being a white lion could account for Nyota's fur being a lighter cream color than other known lionesses. His white allele combined with the tawny-peach of his mate could account for the lightness of his first-born offspring.
