Asura (Samurai Showdown)

Asura is the main protagonist of Samurai Showdown 64: Warriors Rage alongside Shiki, he's occasionally depicted having eight black wings in various appearances (though they are never shown in actual gameplay).

Story
He is a being who has a long-standing conflict with Yuga the Destroyer, who wreaks havoc in order to bring about "the unification of this world and the Netherworld". Yuga imprisoned Asura in the Netherworld and he subsequently escapes when it is defeated during the events of Samurai Shodown 64. When he confronts Yuga, his clone, Shadow Asura, assists him in slaying the fiend. They fuse themselves together so that his clone could survive.

Later, in Samurai Shodown: Warriors Rage, Asura is revealed to be a shade of the real Asura. His clone was the one who retained the original's memories; this Asura only kept the original's abilities and his animosity for Yuga.
