Porcupine

Porcupine (豪猪 Yama Arashi) was a member of the Shadow Beasts, the elite guard of the Ten Dons.

Appearance
He is a man of small stature, who does not seem to have a nose and always dresses in overalls and flip-flops. His appearance does not rouse much fear; indeed, he almost seems nice if he always did not have a pretty sullen expression. The only hair you can see on his body are the three tiny hairs that form a small tuft on his forehead.

Yorknew City Arc
Porcupine along with Leech, Rabid Dog and Worm are send to kill the phantom troupe members that attacked the auction in Yorknew City held by the mafia, they engage Uvo in battle. Porcupine is the last Shadow Beast to be killed by Uvo when Uvo uses his Enchanced Shout to kill him

Nen Ability
Porcupine is a Transmuter. His ability revolves around manipulating his body hairs as weapons. Just like his code name, he manages to eject (or grow, this is not clear) his hair out of his way that they assume the consistency and size he wishes. Once the barrier is built, nothing will be able to penetrate it. In fact, this ability seems to have been created for defense measures instead of offense.
