@ArtsyGal: Being a huge wad. lol
But hes a sharkman who doesn't have anything comparable to Superboy.
Arlong is one of the fishmen, massive humanoids that are taller and stronger than any normal human. Arlong, however, is a giant even among fishmen. His power was remarked to be greater than Don Krieg, the strongest (military) force in the East Blue, with only Krieg's military might and massive armada forcing the Marines to deem him the bigger threat.
As a fishman, he is ten times stronger than a common human, and even more underwater. However, he seems to possess amazing physical strength even for fishmen standards: he was seen lifting a house with his bare hands in pursuit of Usopp, and his powerful shark-like jaws are capable of bending metal, crushing stone, and ripping through flesh alike. Arlong's fortitude was also displayed when he was able to withstand most of Luffy's attacks. Although Luffy unleashed most of his techniques and forced Arlong back, he was mostly unfazed after each attempt.
He also has incredible endurance to pain: during his fight with Luffy, he ripped off many sets of his rapidly re-growing teeth, and he rearranged his broken nose without a grimace. Arlong is also capable of entering a kind of berserkermode upon angered. When this happens, his eyes take on an appearance similar to those of sea kings. While in this state, both his strength and his speed grow exponentially, making him far more dangerous than previously stated.
Arlong was not bothered by Luffy having a Devil Fruit power and took advantage of his weakness to the effects of the sea. With the Marines focusing their attention on the Grand Line and the incapacitation of all other major East Blue pirate bands by the Straw Hats, there would have been nothing to stop them from taking over East Blue if the Straw Hat Pirates had not intervened.
Arlong's weapons are mostly natural features of his sawshark fishman body. With his expertise in fishman karate, something as harmless as a handful of water can strike as hard as a bullet. He was seen killing Bell-mère with aflintlock
Even his nose is a weapon. It is over a foot long and lined with razor-sharp points, and more than sturdy enough to use as a melee weapon. Swinging his head back and forth, Arlong defeated Zoro (who was weakened by the massive wound given to him by Mihawk previously and his fight with Hatchan) in a swordfight with this natural blade. He is very proud of his nose and claims his nose is unbreakable. However, Luffy managed to twist his nose in another direction during the fight.
He can remove his massive teeth and snap them at opponents like castanets, almost like hand-held foothold traps. The teeth are replaced by a new set in mere moments, each regrown mouthful stronger than the one before. Luffy demonstrated, however, that these teeth can also be used against Arlong, either by holding them in his hands or as he chose, fitting them in his mouth and biting his opponent with them. However, Arlong states that only a fishman can fully utilize the strength of the teeth as he possesses greater strength than a human.
- Shark on Darts (鮫・ON DARTS（シャーク・オン・ダーツ） Shāku On Dātsu): Arlong shoots at his opponent like a torpedo with his apparently unbreakable nose. This attack is simply called Shark Darts in the Viz Manga and FUNimation dub and Shark and Awe in the 4Kids dub.
- Tooth Gum (歯ガム（トゥースガム） Tūsu Gamu): Arlong pulls out his own teeth and puts them in his hand to use them as a weapon, immediately growing another pair in his mouth. He usually uses one set of teeth in each hand. In the Viz Manga and FUNimation dub, this is called Tooth Attack.
- Shark on Tooth (鮫・ON 歯車（シャーク・オン・トゥース） Shāku On Tūsu): Arlong opens his mouth and starts spinning towards the opponent and bites down on them. The kanji used for Tooth is that of Haguruma which means "gear" in Japanese in the manga. This is called Shark Tooth Drill in the Viz Manga and FUNimation dub and Shark and Destroy in the 4Kids dub.
