Shūran

is the lightning user of the Panther Devas. The panthers are the sworn enemies of the dog demons, which brought them into conflict with Inuyasha's father.

History
Many Centuries Ago, Inuyasha's father battled the Panther King and killed him. The 4 Siblings of the Panther Demon Tribe fought along side their master in this battle, losing to Inu No Taishō and his soldiers, Lord Sesshōmaru being among them. After the humiliating defeat, The Panther Demon Tribe swore revenge against the Dog Demons, promising that one day they would repay them for the death of their master. Many years later, about 50 Years before the start of the story when Inuyasha was still bound to the Sacred Tree, The Panther Demon Tribe returned, attempting to regain control of the western lands. However, Lord Sesshōmaru stepped in and defeated them, sending them back to the east with the assistance of some other demons (notably Rōyakan) who felt grateful to Sesshōmaru's father for defeating the cats the first time.

Powers
Like all four of the Panther Demon leaders, Shūran's name is a reference to one of the Four Seasons. Shūran is associated with Autumn, and his powers reflect that. He has the ability to manipulate lightning, blasting bolts of electricity from his hands, (very similarly to Hiten). Along with his lightning powers, Shūran possesses great brute strength, being the largest of the four Panther siblings.

Revived by Tenseiga
When the Panther King is resurrected by the power of the Shikon shards, he requires flesh and a soul to completely reanimate his body. The Panther tribe had gathered several humans for this purpose, planning to sacrifice them in order to revive their master. However, the Panther King proves to be impatient, and steals the souls of Karan, Shūran, and Shunran in order to regain his own power. However, Lord Sesshōmaru uses his Tenseiga to take their souls back, thus reducing the king to his former mummified self, allowing Inuyasha to deliver the final blow with Tessaiga and kill the Panther King once and for all.
