Uvogin is the eleventh member of the Genei Ryodan. Nobunaga has compared his personality to Gon's, seeing how not only do they have the same Nen type, but their behavior is similar as well, being impulsive and short tempered. Uvogin is one of the Genei Ryodan that originated from Ryūseigai. However, like all of the Genei Ryodan, Uvogin doesn't hesitate to kill anyone. Out of all of the Genei Ryodan, Uvogin is the strongest in terms of physical power. Although he prefers to fight alone, Uvogin works best when fighting with a partner (specifically, Nobunaga) as he fights better when he has someone else to protect, though he would never admit it.
Uvogin and Kurapika fought alone in the outskirt deserts of York Shin where Kurapica eventually pierced him with his Chain of Judgement. During the final moments of the conflict Kurapica told Uvogin that if he spoke again dishonestly then he would die, but if he spoke true he would let him live just a little longer. He lastly orders Uvogin to reveal the location of his comrades to which Uvogin tells him to go to hell and subsequently dies as of the Judgement Chain. Uvogin's death is of significant importance to the Genei Ryodan arc.
Big Bang Impact: Uvogin has seasoned his nen to the point where he has 100% power in the reinforcement type. He can strengthen his muscles to the point where neither bullets nor missiles will have much of an effect on him, and can strengthen even his vocal cords in order to kill someone internally. His favorite ability is his "Big Bang Impact", where Uvogin focuses all of the aura to his fist with kou and lets loose, creating an impact as powerful as a bomb.
