Momonga

Momonga has incredible strength as he was able to easily kill a Sea King which is tough enough to resist gunfire and cannonballs without taking any damage. Momonga is also extremely agile, as shortly after he dived inside the Sea King’s stomach through the mouth, he swiftly killed it. He has a strong tolerance to pain as he readily stabbed his own hand to resist the effects of Hancock’s petrification powers.

Rokushiki

Momonga can use at least two of the Rokushiki techniques. During the Summit War of Marineford, he is seen using Soru and Geppo against Monkey D. Luffy.

Swordsmanship

Momonga is a highly proficient and powerful swordsman, as seen when he could kill a Sea King with his sword from the inside of its belly. He is seen employing swordsmanship with his Rokushiki techniques. In the anime, he could cleanly slice Panz Fry’s gigantic soup ladle made of metal and also take down the giant in a single slash.

Weapons

Momonga carries around a katana with a flower-shaped octofoil tsuba and a brown hilt-wrapping, attached to his right hip, which may suggest that he’s either left-handed or ambidextrous. He also has a tanto, which he used to inflict pain on himself to prevent himself from getting petrified by Hancock’s Mero Mero no Mi.

Haki

Like all vice admirals, Momonga is capable of using Haki. He possesses the ability to use Armament and Observation Haki.

After a Buster Call attack has been ordered on Enies Lobby, Momonga and fellow vice admirals Onigumo, Doberman, Strawberry, and Yamakaji are suddenly summoned by John Giant to lead the attack as they were the closest to the location during that time, not knowing that the order was an accident caused by CP9 Director Spandam, who accidentally pressed the golden Den Den Mushi, “given” to him by Aokiji, while retreating from the Straw Hat Pirates and their allies. Thus, Momonga and his fellow Marines set the entire judiciary island on fire with their cannons. Though the Buster Call attack is able to practically destroy almost everything on the island, Momonga and his fellow Marines aren’t able to annihilate a single one of the Straw Hats and their allies. Having destroyed an important World Government base and not dealt any significant damage to the invaders that were causing the disturbance there, Momonga and his fellow Marines are faced with a devastating defeat.

Summit War Saga

Amazon Lily Arc

Momonga was ordered to retrieve the Warlord of the Sea Boa Hancock and take her to the compulsory Warlord summoning in order to prepare for an attack from Whitebeard should he attempt to rescue the captured Portgas D. Ace from being executed. Momonga and his men took a battleship to Amazon Lily in the Calm Belt. Knowing the treaty the World Government has with the Kuja of the island stating that they were not allowed within three kilometers near the island, Momonga and his men anchored in the middle of the Calm Belt and waited for Hancock. Although their presence was masked by the Seastone that lined the bottom of their battleship, they were still attacked by a Sea King that their guns and cannons could defeat.

Fortunately, Momonga was able to slice the monster up from within and saved his men. Eventually, they were able to meet with the Kuja Pirates. Tired of waiting for Hancock, Momonga demanded the Pirate Empress to come out, to which she complied alongside her sisters. Telling her that Ace would be executed at Marineford in a week, Momonga gave her an order from the Marines to come with him since she had complied with the summons. Learning that she had simply lied about supporting the World Government during this critical moment, Momonga threatened to have her Warlord status revoked unless she complied. Instead of a compliance, Momonga and his men received her continued refusal and a taste of her powers. Momonga was able to guard himself from her powers by stabbing himself, but his men were not as fortunate and were turned into stone. With only himself left, Momonga told Hancock that he would wait for her to come with him as long as he could. With a determination to not return empty-handed, he told her that after two days, if she did not comply by then, the treaty with the Kuja would be broken.

Impel Down Arc

After waiting diligently and fighting off another Sea King, Momonga’s vigilance paid off; Hancock decided to travel with him to Marineford, with the condition that they visit Impel Down on the way (her given reason being that she wants to see the one responsible for the war). Momonga complied after Hancock returned his crew back to normal, and having completed his mission, Momonga and his crew headed to Impel Down, not knowing that Monkey D. Luffy was tagging along. Arriving at Impel Down, some members of his crew told him that they saw pirates that they remembered seeing before. But because they could not remember the crew’s name, he said that it was not important. So, they kept moving forward. Arriving at Impel Down, the Marines stationed there saw him and his crew and let them in as he, Hancock, and a hidden Luffy got off the boat, and walked towards the gate. Momonga told Hancock that because she was still a pirate, she must wear seastone handcuffs and undergo a full body-check before they could go in. She agreed and they entered Impel Down. Inside, they met Vice Warden Hannyabal, who took him and Hancock to a lift to meet the prison warden on the fourth floor. After meeting Ace, Momonga left with Hancock, and was told by Zott that Kaidou had attempted to attack Whitebeard, only to be intercepted by Shanks. They then headed for Marineford.

Marineford Arc

Three hours before Ace’s execution, Momonga listened to Sengoku’s speech about Ace’s past. Momonga slashed cannon balls fired by the Whitebeard Pirates and prepared to fight them. Momonga was still standing alongside Doberman and other vice admirals when Whitebeard attacked the Marines after reaching the plaza. When Luffy managed to pass the wall and almost reach Ace, Momonga was among the Marines that stopped and nearly killed him. He hit Luffy with his sword, demonstrating a great ability in semi-aerial sword fights. In the anime, Doma fought him when he tried attacking Luffy again. He was visibly-shocked when Garp was defeated by Luffy. When Luffy managed to free his brother, Momonga opposed Donquixote Doflamingo, who wanted to let the two of them escape in order to have more fun, while Momonga clearly wanted to stop them. After Shanks arrived and called for a ceasefire, Momonga stood down along with the other Marines.

Dressrosa Saga

Zs Ambition Arc

Momonga is tasked with transporting Panz Fry across the Maubeugemour Sea to Impel Down. He is first seen asking the giant why he was on board the government’s cargo ship, and Panz Fry replies saying that he was just trying to provide for the people who the Marines had stolen food from to supply the World Nobles’ nightly feasts, and that he had to do that because the New World had been in chaos since Whitebeard’s death. Momonga counters by saying that the pirates were the ones responsible for the world’s imbalance, not the Marines, and the two agree that they have irreconcilable views. Zoro defends against Momonga. Shortly after this, the Straw Hat Pirates emerge and attempt to free Panz Fry.

Momonga attacks Luffy and then gets in intercepted by Zoro, who is able to put up a good fight against him. Suddenly Shuzo appears and Momonga comments on how he knows him. Shuzo says he wasn’t aware he was on board, and asks him if he is a vice admiral now. Momonga asks Shuzo if he has been the one responsible behind the pirate raids to which Shuzo proudly confesses and announces he intends to cut off Panz Fry’s head. Momonga asks why he is doing this if he used to be a former Marine, to which Shuzo replies that he is doing it for the sake of Z, which surprises Momonga.

Shuzo says he will kill all of them right then and there and tells Alpacacino to kill Panz Fry. Right before Alpacachino’s cannonballs reach Panz Fry, Momonga cuts the cannonballs in half, saving Panz Fry. He then tells Shuzo that he will not allow the Neo Marines to have their way as long as he is commanding that ship. Sanji chimes in finding him very sensible for a Marine soldier, earning disgust from Shuzo calling the Marines shameful. Momonga angrily tells him to shut up.

As the two are about to fight, Luffy approaches them both announcing he doesn’t care about their dispute and will stop at nothing to rescue Lily’s father, challenging them both. When Shuzo and Luffy begin battling, Momonga charges them both announcing he will not let them do as they wish on his ship. Zoro then intercepts him again, pushing him back. The two begin a fierce fight, as Zoro uses 360 Pound Phoenix technique, managing to overwhelm him but pushes the force of the slice away, destroying one of the warships. Shuzo and Momonga then combine their efforts against the Straw Hats together to try and defeat them.

A Thrust Up Stream charges beneath the raft and blows it apart, ending the fight between the three as the Straw Hats escape with the prisoner. Afterwards, Momonga is seen with his remaining crew on a capsized warship. Shuzo returns from his sub to finish their fight as the two battle one last time, destroying the capsized ship. The outcome of the fight is unknown. Still afterwards Shuzo is seen to have returned to his ship, indicating that he had beaten Momonga. Momonga catches up to Shuzo and his remaining soldiers and captures him after they are defeated by the Straw Hat Pirates. Shuzo is surprised he survived their fight and asks how he found him. Momonga tells him he used the same trick he used on the Straw Hats. He put a Vivre Card on Panz Fry to track him, a method of tracking pirates he learned from a teacher a long time ago. He berates Shuzo for dragging the Marines into their personal vendetta against pirates and announces he is being sent to Impel Down. Shuzo tells him he’ll never talk no matter how much he is tortured and demands he kill him now while they are still in the New World. Momonga tells him that’s up to the law to decide, and that is how the Marine’s Justice works.
