Rhino fights Killua in a one on one match after being called up by a lottery ticket. During the fight, Rhino consistently gets hit by Killua's Lightning Palm, until his skin is vulnerable for Killua to pierce him with his hand.
As a Chimera Ant, Rhino is already stronger than the average human, and he claims to be 10 times stronger than Baro. Due to his rhinoceros genes, he has very hard skin that cannot be penetrated by normal means. He also used his horns on one occasion to try and impale Killua.
