Although there are many different reasons, Luffy and other members of the Straw Hat crew often have to use aliases to conceal their true identities. Sometimes, they even have to wear different outfits, adding to the confusion when they face enemies.
So what are the aliases that the members of the Straw Hat crew have used in One Piece? Let’s list them below!
Note: The aliases like “Straw Hat” or “Pirate Hunter” will not be counted, as these names are closely linked to the true identities of the Straw Hat crew.

This is the alias Luffy used when participating in the Corrida Colosseum to compete for the Mera Mera no Mi fruit, which was previously owned by his brother Ace.

2. Luffytaro
This is the name Luffy used when “blending in” during his time in Wano – the land of the samurai.

This is the name Usopp gave to Luffy when talking to the Tontatta tribe – the dwarf-like people residing in Green Bit.

This is the name used by the people of Wano to refer to the one who defeated the Beast King Kaido. Of course, we know that the one who defeated Kaido is Luffy.

14. Sangoro
This is the name Sanji uses when disguised as a soba seller in Wano.
15. O-Soba Mask
When Sanji wears the Raid Suit, he adopts the name “O-Soba Mask” because he dislikes the identity associated with Germa 66.
16. Sanland
This is another nickname of Sanji created by Usopp to mislead the Tontatta tribe.
17. Chopper Mask
The new alias “Chopper Mask” is used by the hero Chopper when he goes to the Torino country, as he is often misunderstood.
18. Chopa-emon
While in Wano, Chopper also adopts a very cute new alias, which is Chopa-emon.
19. Chopland
When mentioning Chopper with the Tontatta tribe, Usopp also gives the doctor of the Straw Hats a new name, which is Chopland.

23. Franosuke
When Franky is in Wano to find the designs of Onigashima, he is referred to as Franosuke.
24. Fraland
Usopp has given an alias to almost all the members of the Straw Hat crew; Fraland is the name used to mislead the Tontatta tribe.
25. Bonekichi
This is how Momonosuke refers to Brook, as well as the name Brook uses when in Wano.
26. Boneland
Brook is referred to as Boneland by Usopp during his disguise while interacting with the Tontatta tribe.
From Luffy to Brook, all members of the Straw Hat crew have their aliases except for Jinbe. This also helps explain why this crew member only recently joined Luffy on his adventures for a short time. Jinbe has never used any other name.
