Mr. 3 is an officer agent of Baroque Works, his partner is Miss Goldenweek.

Appearance
Like other male Baroque Works, Mr. 3 has his number hidden somewhere on his costume. For Mr. 3 he both has 3's visible on his vest design and one big 3 achieved through his top knot.

Personality
Mr. 3 thinks very highly of himself, and is not afraid to show it. He believes himself to be a master of strategy, using his intellect and total lack of scruples to complete his plans. He also thinks of himself as a great artist, using his wax powers to turn his victims into 'living statues' for his partner to paint over. However, when presented with situation in which he has to fight for his life, he reveals himself as little more than a coward who fears fighting (such as when a rage-filled Brogy was close to completely shattering his wax bonds).

Devil Fruit
Mr. 3 ate the Doru Doru no Mi, a Devil Fruit which allows him to tap infinite amounts of a special candle wax from his body. He can manipulate this wax to form any shape he desires, control its motion in both liquid and hardened states, and harden it to become as strong as steel.

Little Garden Arc
During the series Mr. 3 is sent along with Miss Goldenweek to Little Garden to intercept Princess Vivi and the Strawhats. Here Mr. 3 takes interest in the local pair of feuding giants (Dorry and Brogy) and intends to collect the bounty on both theirs and Luffy's heads simultaneously.

First he makes sure to secretly disable one of the giants and than sabotages one of their duels so that one of them is cut down. He proceeds to try and make statues out of the giant, Zoro, Nami, and Vivi, but Usopp, Luffy, and Carue spoil this event. Eventually after two rounds and a maze of self statues Mr. 3 is defeated by Luffy.

Alabasta Arc
He shows up later in Alabasta to apologize to Sir Crocodile for his failure, yet an unamused Crocodile however simply feeds him to his pet Bananawani.

However, Mr. 3 shows up yet again when Sanji is attempting to free the rest of the crew from the same Bananawani. He used his powers to encapsulate himself in wax while in the gators stomach, and after being freed Sanji simply makes him use his powers to open the jail where the crew was captive and than beats him unconscious.

During Vivi's speech at the end of the Arabasta arc Mr. 3 can be seen in the crowd listening to her in Rainbase. The reason for his presence there is never explained.

Ms. Goldenweek Mini Story
Afterwards, Mr. 3 is shown on Holliday Island where he is needed to turn himself in to free Miss Valentine. However, Mr. 3 decides to escape on his ship and save himself, but is stopped by Mr. 2. Despite being defeated by Mr. 2, Mr. 3 manages to escape, so Mr. 2 is forced to disguise himself as Mr. 3 to free Miss Valentine. However, Mr. 3 is later caught offscreen and is sentenced to Impel Down with Crocodile, Mr. 1, and Mr. 2.

Current Events
Mr. 3 has currently been revealed to be residing on the 2nd floor of Impel Down, appearing more ragged and with facial hair than he had prior to his sentencing, and apparently given up on hope of surviving within his confines.

When Luffy and Buggy entered Level 2 and defeated the Basilisk, Buggy decided to release the prisoners in order to cause a riot. Mr. 3 saw his chance and went out, where he addressed them and said that he would repay the debt for letting him out by helping them to level 3.

Translation and Dub Issues
Mr. 3 and Miss Goldenweek's involvement in the Little Garden was removed in the 4Kids dub. To explain Mr. 3's presence in Rainbase afterwards, the story was rewritten to say he had been following Straw Hat Pirates since Loguetown. However, this created a plot hole as until Whiskey Peak Baroque Works did not know who the Straw Hats were. Mr. 3 was also rewritten to be a joker, telling flat jokes in almost every sentence he spoke, despite being a genius in the original storyline.
