Doflamingo revealed to Law that he was given the authority to command CP0 because he was able to hold secret information about Mary Geoise's "national treasure" which will shake the entire world if its extiensce is revealed in the eyes of the public.
1 Rob Lucci
He is a masked agent, which means that he is one of the stronger members of the organization. Rob Lucci is able to use all Rokushiki techniques, which he combines with his devil fruit to further enhance its attacking power.
After his defeat by Monkey D. Luffy at Enies Lobby, Lucci was dismissed from CP9 by Spandam, who declared him and the other assassins responsible for the Straw Hats' havoc on Enies Lobby. However, within the next two years, he managed to be reinstated into Cipher Pol as part of CP0, this time as Spandam's superior.
With One Piece creator Eiichiro Oda confirming that Guernica was the CP0 agent on the roof, Kaido's best moment in the Wano arc is ruined because it means he didn't reaffirm his pride by killing him for interfering with his fight with Luffy.
That is when the World Government issues an executive order for the CP0 to assassinate a pirate from the worst generation by the name of Monkey D. Luffy who is currently fighting against Kaido. That is the highest priority objective that needs to be executed even if it costs them their life.
The consensus is that CP0 shouldn't be able to challenge the Straw Hat Pirates at their current level of power.
CP0 are the strongest of the world government. Admirals like Akainu are the strongest of the Marines. Yonko like Kaido are the strongest of the Pirates.
considering they stand at the apex of the Marines. One does not simply earn the title "Greatest Military Power" by having power that is easily obtainable. That said, CP0 average members probably rank in just under admiral strength.
Pretty strong. Cipher Pol Aigis Zero, or Cipher Pol 0 for short, is the strongest and most lethal of all the intelligence organizations the World Government has under their command.
Prior to being instated into CP0, she was the secretary of Iceburg; as well as the only female member of CP9. After CP9's defeat at the hands of the Straw Hat Pirates, she and the rest of CP9 were dismissed by Spandam. For unexplained reasons, she was later reinstated and promoted to CP0.
Without a doubt, Luffy is much stronger than Lucci at the moment. Even though he entered his Gear 5th state, Luffy is much stronger than Lucci, even in his awakened form.
He was surely at the same power level than Luffy before the Time-Skip, After Luffy defeeated him, he wasn't even able to move anymore. So you could almost consider it a draw. Now since the TS Luffy got stronger, a lot stronger.
Now that he has awakened, Lucci is most likely much more ferocious than he once was. His Devil Fruit grants him the ability to recover from attacks quicker and, on top of that, most certainly grants him increased speed, strength, and resilience.
Lucci's current strength is unknown, however, he's easily stronger than a Navy Vice-Admiral.
However, Luffy was confident that in Enies Lobby, things would be different. With the help of his two new Gears, Luffy was able to defeat Lucci and free Robin.
One of the biggest differences between them is that the CP-0 report directly to the World Nobles. The Marines, on the other hand, report to the Marine HQ and to other high officials.
1 Vegapunk
Vegapunk is undoubtedly the most intelligent person in the series. While his intelligence has not been tested in the midst of a battle, it is safe to assume that a person who is considered to be at least 500 years ahead of any other person would have no problem using it in battle.
He is also a skilled user of the Advanced Armament Haki. It's impressive that Lucci was able to easily take down such an individual. Lucci's latest feats shocked One Piece fans.
Currently, Spandam has somehow been promoted to CP0, but he doesn't have the same level of power that he once had. In fact, he's now Lucci's subordinate, which is rather fitting, given that he's extremely weak.
Currently, Ryokugyu, Fujitora, and Kizaru are the three Admirals of the Marines in One Piece.
According to Robin, the strongest members of the CP0 are given masks to wear to make them stand out from the weaker ones.
It is a known fact that Kaido has lost to his fellow Yonko and the Navy a combined 7 times and been captured a total of 18 times. While Kaido might be the strongest in terms of raw strength, there are definitely those who can beat him a fight. Write for Us!
Zoro wasn't strong enough to fight Lucci in the Enies Lobby arc, but a lot has changed over the years. Now that he has figured out a way to incorporate Haoshoku Haki into his sword attacks, he is a lethal force to be dealt with.
