Gigantification refers to the process of enhancing the size of organic beings via artificial means.


Gigantification is the procedure to turn naturally born regular-sized people into giants via the means of scientific methods. To date, the perfected version of gigantification has been considered to be impossible to achieve. This is a long-sought process to mankind, as Caesar Clown noted that any scientist who can achieve it would be famed and sought after.[2]

Law talks about the Government's attempts at creating giant soldiers.

The most practical use of gigantification is for military purposes. According to Trafalgar Law, the reason the World Government has been researching the process is the ability to freely create giant soldiers. If they were to succeed in creating armies of giants, no one could stand up to them.[3]

However, by Caesar's grudging admission, outright turning people into giants without any side-effects is impossible by scientific means.[2] He believes that taking advantage of children's growth by using drugs is a more practical process,[4] although this would reduce their lifespan from the strain,[5] and even Caesar admits his inability to ensure sustained health and longevity.[2]


The failed artificial ancient giants that became the Numbers within the Beasts Pirates.

For centuries, many of the most brilliant minds in the World Government have sought to create the gigantification process, but none has reached a breakthrough.[3][2]

At some point, at least twenty years ago,[6] a research was undertaken on Punk Hazard in an attempt to recreate ancient giants. The subjects, although gaining sizes and strengths comparable to genuine ancient giants, were deemed as failures for reasons yet to be explained. Kaido eventually recruited these failures, all of whom became the subdivision of the Beasts Pirates known as Numbers, and they seemingly have lived on Onigashima since.[7]

Recent Marine Research

This is science, not magic! Humans aren't going to grow into giants without effort! I told him to kidnap a bunch of growing kids and shove different drugs down their throats.
— Caesar Clown on gigantification.[4]

Signs of Government research can be found on Punk Hazard.

Vegapunk, the leading scientist of the Marines and heralded a genius whose inventions are 500 years ahead of current times, has attempted gigantification, but even he could not succeed.[4]

Caesar Clown, Vegapunk's former colleague and second-best rival, managed to achieve something of gigantification, which is mainly to force large quantities of dangerous drugs and chemicals into children who are in the midst of their growth period.[4] Although this actually turned his test subjects into giants, this also resulted in many side effects that would lead to their demise in about five years.[5] Because of his unethical and impractical methodology, the Marines rejected his experiments, and even used it as grounds to terminate his tenure.[4]

Caesar's Research

Linlin's dream of gigantifying her family.

After Caesar was kicked out of the Marines, he continued with his unethical experiments on gigantification, due to the accompanying fame of success and the chance to outdo the Government and Vegapunk.[3] The Emperor, Charlotte Linlin, commissioned him to this research, funding him, in order to fulfill her dream of having a tea party with her family of all races on eye-level, since her size is comparable to that of a giant, surpassing her many children; after a failed arranged marriage for her 23rd daughter to the prince of Elbaf, Linlin have given up on reconciling with real giants due to their unbreakable hatred for her, and she decided to focus on gigantifying her family via artificial means instead.[8] Caesar, however, only experimented on children in their growth periods, and cannot work out the side-effect of deteriorating health and lifespan. He long since accepted that it is impossible to create a procedure to turn normal humans of any age into giants without any adversity, but repeatedly lied to Linlin by saying he needs more funding to achieve the breakthrough. He only spent a minimal effort on experimenting on the children, and the rest of the excess funds on a hedonistic lifestyle.[2]

After Monkey D. Luffy and Trafalgar Law destroyed his lab at Punk Hazard, Caesar used this as an excuse to Linlin on how his "fruits of labor" have been destroyed and that he cannot reproduce it without the state-of-the-art laboratory built by the World Government. The Emperor, however, has long since recreated a replica of the lab via blueprints she acquired, and offered more funding for the scientist to replicate what was destroyed, and place the finishing touches on it. Having his lies turned on him, Caesar told her he could have the gigantification drug within two weeks at most, and instead was desperately thinking of a way to escape his situation. Linlin's first son, Charlotte Perospero, gave the scientist the two weeks to bring out what was promised, or face death.[2] Caesar ultimately escaped thanks to the intervention of the Fire Tank Pirates.[9]

Chopper's Rumble Balls

Further information: Rumble Ball

Chopper in his Monster Point form, next to normal human Usopp.

As stated by Caesar, Tony Tony Chopper's Monster Point form, which he can access by consuming a Rumble Ball drug to affect his Hito Hito no Mi transformation, is a form of gigantification.[10] Chopper gains a great number of giant-like traits in this form, including massive size and an exponential increase in physical might. For much of Chopper's life, this transformation required three Rumble Balls to achieve and turned his mind into that of a ferocious beast; in addition, usage of this form for more than a few minutes sapped his energy to the point of threatening his life.[11]

After training for two years, Chopper gained enough control over his fruit to be able to access Monster Point with just the aid of one Rumble Ball, and now maintains his senses in this form. However, he can still only maintain the form for three minutes, and will become too weak to move following usage of this form.[12] Later on, Caesar offered a list of chemicals to add in addition to the Rumble Ball that would extend Monster Point's timespan to 30 minutes, albeit with the addition of more side effects,[10] one known which is that after the effects expires, Chopper will be regress to his "Babyjiji" form, in which his size is greatly reduced to that of an infant, rendering him largely powerless.[13]
