Yamato was capable of holding back Kaido and that's all an Admiral has to do. Kid and Law took down
8/10 Can: Marco
During the Summit War, Marco clashed against all three of the Admirals on an equal footing. He managed to hurt two of the three, showing that he's indeed capable of fighting and possibly even beating them.
They absolutely possess the weapons to take them on and combat, however, defeating them is a different question altogether. The Admirals and the Yonko are certainly not equal in power and the former will always reign supreme as the strongest in the One Piece world, which Oda once again showed in the previous chapter.
However, what makes the three admirals quite formidable is that they all had Logia-type Devil Fruit powers. All of their powers are very destructive, even when compared to an average Logia user.
Kaido probably possesses enough strength to beat Akainu without transforming, but if he does use his dragon form, Akainu won't even scratch him. When Kaido transforms into his dragon form, he gains even more inhuman durability because of his scales.
Garp doesn't use Devil Fruit powers, making him a completely Haki based fighter. Although he may not be able to defeat him as he is now, in his prime, Garp would certainly prove to be more than a challenge for Kaido.
Garp is easily the most powerful Vice Admiral in the Marines, and rivals or exceeds the power of the known Admirals and Fleet Admirals. After then-Admiral and future Fleet Admiral Sakazuki (also known as Akainu) killed Ace, Fleet Admiral Sengoku held Garp down to prevent him from killing Sakazuki in revenge.
Nobody can solo the three admirals, even two is impossible. The admirals are the three great powers of the navy.
Biggest Achievement: Kizaru is considered by many to be the strongest Marine Admiral, which is mainly due to his Pika Pika no Mi. Kizaru's abilities make him a dangerous opponent and not many characters match his speed.
Yamato was capable of holding back Kaido and that's all an Admiral has to do. Kid and Law took down Linlin, two Admirals would decimate her. Once that happens, Three Admirals at the same time vs Kaido would destroy him in a minute. Admirals also has greater teamwork than two yonko.
3/15 Sakazuki, The Strongest Active Marine Right Now
Formerly known as Admiral Akainu, Sakazuki is currently the Fleet Admiral of the Marines, and acquired this position after beating Aokiji on Punk Hazard. As the Fleet Admiral, it goes without saying that he's incredibly powerful.
2/5 Kaido. The man known to be the strongest creature, Kaido is widely known to be the most powerful pirate right now, and the mightiest of all Yonko currently.
So yes,Luffy can take the Admirals as well as Smoker. I think that we can only wait and see how he does against a Logia user, as he is soon to fight Ceasar Clown.
The rank of admiral (or full admiral, or four-star admiral) is the highest rank normally achievable in the U.S. Navy. It ranks above vice admiral (three-star admiral) and below fleet admiral (five-star admiral).
Kizaru is likely One Piece's weakest Admiral seen thus far. Despite having the strongest Fruit on paper of the five Admirals seen, he never utilizes it to its fullest potential. While still an Admiral and therefore incredibly strong, he's most definitely the weakest of the bunch.
Dragon's true strength hasn't been revealed yet, but his No. 2, Sabo, was strong enough to take on an Admiral, Fujitora, in battle despite having poor control over his Devil Fruit at the time. This implies that Dragon is stronger than a Navy Admiral at the very least and capable of rivaling Kaido.
What i think guys dragon is a former admiral during the era of Z. While being admiral he and Z both saw that the WG is only trying to dominate the world, it is not at all justice they admired so they both left WG.
To counter Katakuri's Future Sight, comparable Observation Haki or much greater raw speed is needed. King possesses the required speed. However, to reach such quickness, he has to lower his otherwise unparalleled durability. King beats katakuri with high diff and it's not even a debate.
he can beat those two yonko for sure. His power and haki and stamina are way too strong for these two yonkos.
By coating his fists with Haki, Garp was able to demolish mountains with ease, which is a very impressive Haki feat. Even though he is past his prime, Garp has shown that he could injure Marco, and he was confident that he could have killed Akainu at Marineford.
He demonstrates proficient usage of Busoshoku Haki, being able to injure Luffy several times, bypassing his rubber body. He was also seen crushing Chinjao's uniquely shaped head with a Haki imbued punch 30 years ago, by hardening his fist and turning it obsidian black to increase the damage inflicted.
However, that's not to say that Kaido has never lost. 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.
Monkey D. Luffy defeated Kaido. Luffy and Kaido fought on two different occasions. Luffy first fought with Kaido when Kaido had destroyed Oden's castle.
The Reason why Law can't kill Kaido by simply taking his heart out and stabbing it - One Piece. It's very simple. Law's Ope Ope no Mi devil fruit grants him no cutting abilities. Law needs to be strong enough to cut and kill someone to perform his surgeries.
