Shark

Shark (シャーク, Shāku) was a thug hired by a certain village to be the guardian of their water reservoir. The village was located 3km to the east to where Toyo and her orphans lived. One night, while Kenshirō, Bat and Lin were staying at Toyo's home, Taki (one of Toyo's orphans) sneaked into the village to get water for Toyo. However, Shark caught Taki as he was getting away and shot Taki with his bowgun, mortally wounding. Kenshirō arrived too late to rescue Taki and in retaliation he chopped Shark's head in half with his hand.

In the TV series, Shark is unable to catch Taki, who is accompanied by Bat on his buggy when they steal the water, nor does he get killed by Kenshirō. The name "Shark" was not used in the original manga nor in the TV series and only appeared in the Hokuto no Ken Online computer game. Despite his animal-themed name, Shark was not a member of Jackal's gang.
