Sunagumo

An Asura warrior who had not yet earned himself a name. He fights using the Shura Nindō style and at the age of fifteen it was said he single-handedly routed a 100 of Akashachi's crew, as well as taking Akashachi's eye and leg, during the pirate's botched raid on the island.
When a weakened Falco visited the island in search of the abducted Lin, the Nameless Asura ambushed the outsider and removed his artificial leg. Kenshiro arrives to find the moribund Falco and engages in a brief clash with the Nameless Asura, who initially surprises Ken with his speed and agility. However, Falco cuts short the battle in his desire for a rematch and has Kenshiro strike his Sekkatsukō vital point to give him the strength needed for one last showdown.
The Nameless Asura is overpowered by the rejuvenated Falco and buries himself underneath the sand for a sneak attack. Falco freezes the ground to detect the Nameless Asura's position before heating it up to force him out of hiding. The Nameless Asura leaps out of the burning earth and descends on Falco with his Venomous Spider Hand Blade technique, but Falco blocks it with one hand and slices him clean in-half with the other. With his final words, the Nameless Asura warns them that even greater demons await them from here on in.
The term Nameless Asura can be used to apply to other shuras who haven't earned a name. Falco derisively calls him Sunagumo (砂蜘蛛, "Sand Spider"), which has become a popular nickname for the character.
