Shūran

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

History
Many centuries ago, Tōga battled the Panther King and killed him. The four siblings of the Panther tribe fought alongside their master in this battle, losing to Tōga and his soldiers, Sesshōmaru being among them. After the humiliating defeat, the Panther tribe swore revenge against the dog yōkai, 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 tribe returned, attempting to regain control of the western lands. However, 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 his father for defeating the cats the first time.

During the story
When the Panther King is resurrected by the power of the Shikon Jewel 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, 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.

Physical description
Shūran is a panther yōkai with tanned skin, and black hair and catlike eyes. Like the other Panther Devas, he has pointed ears, fangs, and claws. He is the largest of the Panther Devas, and also has a thick brown catlike tail. His outfit consists of a green vest with metallic shoulder plated with three bangles on each one. He wears dark navy pants and shoes with a pelt and fur leggings. He wears a pair of dark navy armbands. He wears a kind of gold panther head-shaped tiara.

Powers & Abilities
Like all four of the Panther Devas, 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), as well as creating flashes of light to blind his opponents.

Along with his lightning powers, Shūran possesses great brute strength, with one of his punches being able match a kick from Kōga.
