Momonga

Vice-Admiral Momonga (モモンガ中将, Momonga Chūjō) is one of the five Vice-admirals, who lead the Buster Call on Enies Lobby. He eventually returns as the Marine representative meeting with Shichibukai member Boa Hancock near her home island of Amazon Lily.

Appearance
Momonga is a man with a mohawk and a mustache. He wears the standard Marine uniform, consisting a pinstripe suit and a coat draped over his shoulders, much like Kizaru. He is of average height and very well built.

Personality
Vice Admiral Momonga is very serious. He is stern and deadset on completing all of his mission. As of yet, it is uncertain what type of "Justice" he follows, although it appears to be sincerely concerned on the welfare of his subordinates. Though he is sometimes easily annoyed by their incompetence, as seen when they quickly fell for Hancock's charms. He is apparently smart being that he figured out what would happen and a way to block the affects of Boa Hancock a Shichibukai's Mero Mero Merrow beam in mere seconds, but even he is not immune to Boa Hancock's beauty as seen in episode 423 when she opens her eyes and looks into his after she fainted.

Abilities and Powers
Boa Hancock: I see... You used the pain to silence your wicked heart. A mark of experience. However, your soldiers are no more. Your crew is down to one. Momonga: One... Is not the same as "none".

-Hancock and Momonga talk

As a Vice-Admiral within the Marines, Momonga has respect and abilities in both mind and body. When he waited to collect Hancock, he had killed a Sea King from the inside. Similarly, he was able to block Hancock's Devil Fruit abilities by stabbing a knife in his hand, using pain to block the lust that consumed the rest of his crew and turned them into stone. Hancock stated that it was his experience that prevented him from being affected by her power. Momonga also leaves Hancock with a warning that even without his men he was still dangerous.

In battle Momonga seems to be a formidable swordsman as seen able to kill a Sea King from the inside and having the ability to cut steel with his sword. During the Marineford battle, he used some of the Rokushiki techniques such as Soru and Geppou against Luffy with another Marine Officer who also used Rokushiki (Soru and Shigan).

The Enies Lobby Incident
After a Buster Call attack was ordered on Enies Lobby, Momonga and his fellow Vice-Admirals Strawberry, Yamakaji, Doberman and Onigumo were summoned suddenly by John Giant to lead the attack as they were the closest to the location. Unbeknown to him and his fellow Marines, the order was an accident caused by the CP9 director, Spandam, accidentally pressing the Golden Den Den Mushi, "given" to him by Aokiji, while retreating from the Straw Hats and their allies. Without knowing the true reason, Momonga and his fellow Marines set the entire judiciary island on fire with their cannons. Though the Buster Call attack was able to practically destroy almost everything on the island, Momonga and his fellow Marines weren't able to annihilate a single one of the Straw Hats and their allies. Having destroyed an important World Government base and not deal any significant damage to the invaders that were causing a ruckus there, Momonga and his fellow Marines were dealt with a devastating defeat.

Amazon Lily Arc
Receiving orders to retrieve the Shichibukai, Boa Hancock, to the compulsory Shichibukai summoning to prepare for an attack from Whitebeard should he attempt to rescue the captured Portgas D. Ace from being executed, Momonga with his men took a battleship to the Calm Belt where Hancock's home, Amazon Lily, was. Knowing the treaty the World Government had with the Kuja of the island stating that they weren't allowed within three kilometers near the island, Momonga and his men anchored in the middle of the Calm Belt and awaited for Hancock. Though their presence was masked by the Seastone

that lined the bottom of their battleship, they were still attacked by a Seaking that not even their cannons could defeat. Fortunately, Momonga was able to slice the monster up from within and save 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 in Marineford within one week, he demanded that she 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 Shichibukai status revoked unless she complies. 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, his men weren't as fortunate and were turned into stone. With only himself left behind, Momonga told Hancock as she left that he'll wait for her to come with him as long he can. With a determination to not return empty handed, he told her that after two days if she doesn't comply by then, the treaty with the Kuja would be broken.

Impel Down Arc
After waiting diligently and fighting off another Seaking, Momonga's vigilance paid off, Boa Hancock decided to travel back with him to Mariejois. With the odd request to visit Impel Down on the way, Momonga complied as Hancock returned his crew back to normal. Having completed his mission, Momonga and his crew headed to Impel Down, not knowing that someone else was tagging along. Arriving at Impel Down some members of his crew told him that they saw the Buggy Pirates that they remembered seeing before. But because they couldn't remember what it was called he said it wasn't important and so they kept moving forward. Arriving at Impel Down the marines there saw him and his crew and let them in. As him, Boa Hancock, and Luffy (who was in her cloak) get off the boat, and they walk towards the gate he tells her that because she is still a pirate she will have to wear seastone handcuffs and undergo a fullbody check before they go in. She said "so be it" and they enter Impel Down. Vice-admiral Momonga and his crew (with a hidden Luffy) then arrived at Impel Down.

There he meets Vice Warden Hannyabal, who takes 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 his subordinates that Kaidou tried to attack Whitebeard, only to be intercepted by Shanks. They then headed for Marineford.

Marineford Arc
Three hours before Ace's execution, he was seen listening to Sengoku's speech about Ace's past. He is later seen slashing cannon balls fired by the Whitebeard Pirates and prepares to fight them. Momonga was still standing alongside Doberman and other vice admirals when Whitebeard attacted the Marines after reaching the plaza. When Luffy manages to pass the wall and almost reaches Ace, Momonga is among the Marines that stop and nearly kill him. He hits Luffy with his sword, demonstrating a great ability in semi-aerial sword fights.
