Trivia

 * Suicune is partially inspired by Fujin (the Japanese God of the Wind, complimenting Suicune's nickname as the "North Wind") who wore a leopard skin. So, Suicune's appearance is also partially based on that of a leopard. However, its also got some wolf-like traits as well, with a longer muzzle and lither body than its more feline brethren. The "horn" on its head and power to purify water also gives the impression it could have some Kirin influence. http://i49.tinypic.com/28bxngn.jpg
 * It is believed that Suicune, before it perished in the Burnt Tower, was a Vaporeon. This is supported by the fact that the Burnt Tower is in Ecruteak City, a city where Eevee and it's evolution forms are very popular. It's behavior is also identical to that of a typical Vaporeon, being generally portrayed as a calm and level-headed Pokemon.
 * Many people believe that Suicune are female.(This can be proved if you look at Suicune's trophy in Super Smash Bros. Brawl. If you look closely, Suicune's waist looks curved.) Suicune's cry, type (Water) and powers also contribute to this speculation. The name " Aurora Pokemon " also hints that Suicune are in fact female. Auroras are commonly associated with feminine figures.
 * Suicune is the only one of the Legendary Beast trio to be a version mascot.
 * Ash saw a Suicune at the beginning of his Johto journey making this the second time Ash has seen a legendary Johto Pokemon at the beginning of his journey.
