One Piece: 6 Worst Mothers In The Series, Ranked

These One Piece characters are far from being ideal mothers.

Most of these characters rely on their physical and devil fruit abilities to get the better of their opponents. Such characters never fail to capture the attention of the fans, but sometimes physical strength alone isn’t enough to win a fight or get out of a tricky situation. In such cases, the smartness of a character comes into play. Needless to say, there are many knowledgeable characters in One Piece, but not all of them are smart.

Updated on February 8, 2024, by Suzail Ahmad: One Piece has entered its final stretch, which means that the story is not far from its conclusion. Due to this reason, all the characters that have been avoiding the action will soon have no other option but to get involved.

With their wit, these individuals have achieved many great things, which puts them among the smartest characters in One Piece.

22 Akainu

Extremely Manipulative


Akainu may be the most hated Marine in the series, but it is hard to deny that he stands among the strongest One Piece characters. He is the current Fleet Admiral of the Marines, a position that he obtained after defeating his fellow Admiral, Aokiji, in a brawl in Punk Hazard.

Akainu is considered a brute, but the reality is that he is a cunning individual. During the Summit War, Akainu manipulated Squard and turned him against Whitebeard. He stopped Ace from escaping by badmouthing Whitebeard. Akainu is shrewd, and he can sow seeds of discontent among people, causing them to make foolish decisions.

One Piece: 6 Strongest Haki Users In The Final Saga

These One Piece characters are going dominate the Final Saga with their monstrous Haki.

At the moment, there is very little reason to doubt Kuzan’s loyalty towards the Blackbeard Pirates, but it is unwise to rule out the possibility entirely. He also seems to have ties with the Underworld, which makes his decision to leave the Marines even more interesting. A person of his stature would normally have no connection with the Underworld, unless there was something that he was specifically looking for. There is a chance that he joined a Yonko’s crew because he wanted to bolster his chances of achieving that specific goal, in which case he would be using Blackbeard.

19 Clover

Lead The Scholars Of Ohara

Nearly Outsmarted Whitebeard

Sengoku Yonko Level One Piece

Only Straw Hat Who Is Both Smart And Strong

One Piece Sanji Straw Hats Bounty Wano

Sanji is a very intelligent character, and it wouldn’t be a stretch to call him the smartest Straw Hat Pirate. He is a culinary genius, who knows about all kinds of ingredients and their benefits. Sanji’s intelligence can also be seen in and out of fights.

During the Alabasta arc, Sanji managed to fool Crocodile, which gave him enough time to save the Straw Hats. He destroyed the machinery of the Ark Maxim, slowing down Enel and giving Luffy ample time to defeat the villain.

3 Blackbeard

Most Shrewd Pirate

Blackbeard from One Piece

Many people believe that Blackbeard will be Luffy’s last opponent, and he has exhibited many signs of being the final boss.
