Water Empowerment: When his body is hydrated enough, Deep Sea King changes to his "natural form". In this form, he is much larger and more monstrous. However, certain attacks (like those delivered by Genos) or long periods of dryness cause him to exit this form.
Augmented Strength: In this form he boasts greater strength, being able to smash through buildings with more ease than before.
Augmented Speed: In this form his speed increases greatly, as he is able to keep up with Sonic for a considerable amount of time, forcing him to retreat.
Immense Strength: The Deep Sea King boasts an extreme amount of strength seen as how he was able to dispatch two A-Class heroes with minimum effort. In his weakened state, he was able to greatly damage and send Puri-Puri Prisoner, an S-Class hero, flying towards a building a great distance away. He was even able to tear apart Genos's cybernetic body. However, in his dry form, he was unable to land any decisive blows on Genos, despite the hero only having one arm, until he used his acid spit.
Body Moray: He can release a long eel-like creature from his mouth that he can use to bite and tear into opponents with. According to the Deep Sea King, the creature will not go away once it latches onto his enemies. Its full capabilities are unknown, and its maximum length is also unknown.
Immense Durability: The Deep Sea King has incredible physical might, being able to easily withstand the attacks of several heroes ranging from C-Class to S-Class with little damage, despite them occurring one after another with little rest in between. In his dry state, he could take powerful punches of the S-Class hero, Pri-Pri-Prisoner, head-on without much visible damage, alongside the attacks of Speed-o'-Sound Sonic (an S-Class villain), and the S-Class hero, Genos.
Immense Speed and Reflexes: The Deep Sea King boasts an exceptional amount of raw speed, as seen when he was able to appear behind Lightning Max instantaneously, catching the A-Class hero off-guard and struck Stinger (another A-Class Hero) before the latter could react. However, he was shown to be outmatched against Sonic in terms of speed and could not land a proper hit on the ninja until he entered his true form. Along with this, his dry form was shown to be about on par, if not slightly below, the level of Genos.
Regeneration: While shown to be highly resistant to attacks, the Deep Sea King is capable of recovering from his injuries at an extreme rate, as seen when an injury he received from Genos, an S-Class hero, healed while they were still fighting. However, this ability does have limits, as a powerful blow can kill him before he has the chance to regenerate.
Acid Spit: The Deep Sea King could shoot acidic spit from his mouth. It was able to melt Genos's metallic body almost completely. The spit is a lysis solution that also breaks down the membrane of cells.
Enhanced Senses: Deep Sea King appeared to be able to sense people's presence in every direction, even if distant.
Expert Hand-to-Hand Combatant: The Deep Sea King was shown to be a very skilled combatant capable of defeating two S-Class heroes, and seemed to have lots of combat experience, as seen when he lectured Puri-Puri Prisoner on how to fight properly, by putting much more effort into attacking an opponent with more intent to kill. He also seemed to have a preference for combo attacks, attacking his opponents mostly with a barrage of punches.
Barrage: Deep Sea King unleashes multiple underhand punches into his opponent. Each punch is powerful enough to leave marks in Puri-Puri Prisoner's body. It was used against Puri-Puri Prisoner.
