Devotion

In that arc we knew that Vivi was a princess of Alabasta and in that arc we'll know the first enemy boss that Luffy will face in grand line.

So that arc is quite important. As we know now with recent chapters that Vivi had an important role in One Piece since Imu is quite fixated with her.

But on this arc Oda introduced us to Robin (who's quite important as she is the map to One Piece) and he also showed us how capable Zoro is (which is why he's the right hand man).

Just ignore me if you can't understand me, but if you see the connection then keep on reading.

Half of the arc was focused on Zoro defeating 100 bounty hunters which contributed or one of the reason why he was issued a bounty (the other reason is that he defeated Mr. One).

Thus (sorry for the power scalers out there) Luffy's second-in-command is Zoro. He knew that something wasn't right when he heard the nick names for BW, and he was on guard at that time but he still let his captain and crewmate rest while he eliminates the threat.

While Robin was introduced in an arc where Zoro was the main character.

I just love that in this arc shows us the connection of Robin and Zoro. The two of them were both second-in-command of their boss.

These two people are really cool. Even when they were swept away by the whitestrom.

Robin really is a grace under pressure person.

Zoro is so nonchalant about the danger.

“I will cause fear” is more transitive than “I will indulge in rage” is what I'm saying. cause whose fear? which does align with how the violence the creature commits is in the name of trying to say something to Victor
