Further information: Tony Tony Chopper

Chopperman (チョッパーマン, Choppāman?) is the protagonist of the Chopperman series. He is a hero protecting the peace on Tony-Tony Island. He uses his cape to fly around the island during emergencies. His primary attack is "Kyuun Spark" (キューンスパーク, Kyūnsupāku?), though he will resort to "Chopper Violence" (チョッパーバイオレンス, Choppābaiorensu?) if it fails. He is empowered by friendship, and will become stronger the more people he hears cheering for him. His hat is pink when he's invigorated and white when he's been defeated, but it can be recharged if enough people cheer for his success.[3] His sense of smell is 10,000 times the average.[4]

Chopperman wields the power of the "Cross Power" (〝クロスパワー〟, Kurosupawā?), allowing him to double all his abilities. The power is contained in his hat. When his hat turns white, it means that the Cross Power is primed to be activated, and upon genuine, heartfelt cheering from his companions, the hat becomes dark red. During this time, Chopperman's abilities are doubled, lasting until the threat is defeated. The Cross Power's power only functions if the cheering is a genuine plea from those the wielder is helping, and it cannot be forced.[5]

Air Force C[]

The Air Force C (エアフオースニC, Eafuōsuni C?) is Chopperman's private jet. There are two versions of the jet, a model version and a real plane.[6][7] The model version includes a M61A1 Vulcan 20mm caliber cannon, two missile launchers, and two Aim-9J missiles.[8] The capabilities of the jet version are unknown.


Further information: Nami

Namifia (ナミフィア, Namifia?) is Chopperman's assistant. She works inside Chopperman's Hideout, waiting for emergency reports.[6] However, once the emergency occurs, she will always come with Chopperman to resolve it. Before the heroes discovered Dr. Usodabada's true identity, she did all the investigation work for it, while Chopperman and Zorokiller simply ignored it.[9]


Further information: Roronoa Zoro

Onigiri Mystery Man, Zorokiller (おにぎり怪人 ゾロギラー, Onigiri Kaijin Zorokilã?) is a monster created by Dr. Usodabada to take over Tony-Tony Island. However, he was created without a memory, and does not remember anything from before landing on the island,[6] though he does recover some memories later.[10] He was inspired by Chopperman's friendship with the island's residents and joined his side, helping to defend the island. Like his main series counterpart, he has no sense of direction.[11]


Further information: Sanji

Perverted Monster, Sanjirops (エロ怪獣・サンジロプス, Ero Kaijū Sanjiropusu?) was one of Dr. Usodabada's two monster lieutenants, along with Robinflowan. When he worked with Dr. Usodabada, he very rarely listened to his orders, doing what he wanted instead.[4][9] However, he was motivated by women, and went to Tony-Tony Island when he was told that Chopperman was holding a bikini contest.[10] He refuses to work with anybody who would harm or threaten women, even going so far as to ally with Chopperman when Dr. Usodabada took Namifia hostage.[10]


Further information: Nico Robin

Flower Mystery Woman, Robiflowan (お花怪人ロビフラワン, Hana Kaijin Robifurawan?) was one of Dr. Usodabada two monster lieutentants, along with Sanjirops. When she worked with Dr. Usodabada, she never listened to his orders, to the point of leaving to go on vacation without informing him.[11] Upon returning from her vacation, she ran into Chopperman on Tabetsukusare Island, and asked to join his group instantly due to his cuteness.[12]

He was found by Chopperman in Dr. Usodabada's laboratory and brought to Tony-Tony Island, and began helping to protect the residents.[13]

Tony-Tony Island Residents[]

His soldiers obey him happily, but certain monsters (such as Sanjirops and Robinflowan) don't always obey.

After his defeat at Chopperman's hands, he lost his hearing.[20] This allowed him to be immune to Black Brook's musical abilities, which in turn allowed him to fake being under his control while infiltrating his gang.[19]

Dr. King Usodabada[]
Further information: Usopp and Sogeking

Ultimate Secret Weapon, Dr. King Usodabada (最終秘密兵器Dr.キングウソダバダ, Saishū Himitsu Heiki Dr. Kinguusodabada?) was Dr. Usodabada's ultimate weapon. It is a mech suit piloted by Dr. Usodabada himself, harnessing Black Brook's musical abilities. It is able to shoot "Ultrasound of Death" (死の超音波, Shi no Chōonpa?), a beam that turns all organic matter it touches into skeletons, as well as Zorokiller's, Sanjirops', and Robinflowan's attacks, to an even stronger degree than them.[21] The mech suit was ultimately destroyed by Chopperman.[7]

Dabada-gang Soldiers[]

The Dabada-gang (ウソダバ団, Usodaba-dan?) Soldiers are a number of unnamed, functionally faceless soldiers who follow Dr. Usodabada's orders. He mostly uses them for large-scale attacks against Chopperman or Zorokiller, but they are always defeated easily.

Death Hatch was abandoned in the ocean, floating with octopuses.

Bara Buggy[]

Further information: Buggy

Red-Nosed Terror, Bara Buggy (赤鼻怪人バラバギー, Akabana Kaijin Barabagī?) was a monster created by Dr. Usodabada to take over Tony-Tony Island after Death Hatch's defeat. He has the ability to fragment his body and remotely control the parts, making him nearly impossible to defeat. However, the residents of Tony-Tony Island discovered that his head could only move so far from his body parts, and they held his separated body in place, allowing Chopperman to defeat him.[3]

Bara Buggy later returned to Tony-Tony Island, during Dr. Usodabada's return. With his increased strength, he was able to nearly defeat Robinflowan, and was immune to Zorokiller and Sanjirops' attacks. However, he was easily defeated by Chopperman.[20]


Further information: Enel

Gorogorobot "Enelgotton" (ゴロゴロボット"エネルゴシトン", Gorogorobotto "Enerugoshiton"?) is a robot created by Dr. Usodabada as a backup measure in case of Bara Buggy's defeat. He was able to summon and control lightning at will, though he could not become it, unlike his One Piece counterpart. However, despite his immense power, he has no will of his own, and is controlled completely by Dr. Usodabada's remote controller. He nearly defeated Zorokiller and Chopperman at the same time, but Chopperman was able to destroy Enelgotton at the last second, forcing Dr. Usodabada to flee once again.[22]

Mokmoker Z[]

Further information: Smoker

Smoke Robot Mokmoker Z (スモークロボモクモーカーZ, Sumōkurobomokumōkā Z?) was a robot created by Dr. Usodabada to guard the first floor of his lair. His strategy revolved around filling the fighting arena with smoke, then using his built-in infrared sensors to track his opponents. However, a weakness in his strategy is that if there are too many heat sources, he becomes unable to track his opponents. Sanjirops took advantage of this to confuse Mokmoker Z, allowing Zorokiller to defeat him.[23]

He was searching for the "Cross Power" (〝クロスパワー〟, Kurosupawā?), planning to use it to take over the world. It would allow him to project his music directly into people's minds, bypassing his only weakness.[5] However, he could not fulfill it's activation conditions.

Takei-sensei's Note[]

In addition to the standard Author's Notes on the sleeve's inside flap, the Chopperman volumes also included a note at the end of each volume, titled Takei-sensei's Note (?).

Takei-sensei's Note
Volume 1 Volume 2 Volume 4 Volume 5
Volume 1
Chopperman (Spin-Off Manga) 001 Takei-sensei's Note I pray that you enjoyed reading this volume and that you'll continue to follow the series with as much pleasure that I have creating it!
Volume 2
Chopperman (Spin-Off Manga) 002 Takei-sensei's Note Thank you for the warm encouragement boosting me up. Rest assured that I do my best to make the series as fun as possible!
Volume 4
Thank you for having read the 4th volume of Chopperman's adventures! I write the manga alone, which represents a fairly large amount of work, and consequently numerous hours spent at my drawing table. Up to now, I sat comfortably on a chair that I've had for years, but unfortunately, my cat made it unusable by vomiting all over it... so my vertebrae risk making me suffer while I break in my new seat. There's a little overview of my workspace (and I won't tell you about the cat's crate!).

See you soon for Volume 5!

Volume 5
Chopperman (Spin-Off Manga) 005 Takei-sensei's Note I infinitely thank all the people involved in the realization of this series, and especially Eiichiro Oda-sensei, of course.

And, of course, to all of you faithful readers who have followed Chopperman's adventures to the end... a big thank you from the bottom of my heart!!
