Arnie "Crocodile" Gregory (アーニー · "クロコダイル" ·グレゴリー, lit. ānī kurokudairu guregorī) is a featherweight boxer from Australia and the former OPBF Featherweight Champion who appeared in Hajime No Ippo: New Challenger.
Arnie Gregory is the former OPBF Featherweight Champion. He is Australian and nicknamed "The Crocodile" because of how very powerful his punches are, especially hooks. His most well-known technique is called Bloody Cross, which he uses against counter-punchers. Although he used this technique as against Miyata Ichirou during their OPBF Featherweight Match, he was ultimately knocked out by Miyata's Jolt Counter. During this match, he fired his manager, Mr Sakaguchi, because of the latter's money-grubbing attitude towards boxing and indifference to the feelings of the fighters.
Outside of the ring, Gregory appears to be a decent man. He is kind towards the Japanese and respects their fighting ideal of "warrior spirit", which he witnesses during his match against Miyata. He is also a bit showy; during his match against Miyata, he entered the ring by jumping over the ropes and throwing his cowboy hat to the cheering crowd.
Following his loss against Miyata, Gregory returned to his homeland, but not before giving his cowboy hat to Miyata as a gift and parting with the words, "Goodbye, Champ."
