In terms of characters: Vivi really grew on me. Her role in the plot was basically to cry and mourn, but she was still a fun character. Most of the others in this arc were great. The king was awesome, Pell was freaking badass, Crocodile was one menacing son of a bitch, and his subordinates were pretty cool as well. The only weak characters were Chaka and Kohza. They were both useless, basically. The latter actually deserves some kind of medal for being one of the most hyped useless characters in any series, haha.
I laughed a lot during this arc too. Arabasta animals rule, hahaha. Even the ones in the filler episodes. The turtle/seal hybrids, the crab, and Eyelashes were great, and so were Carue and the other ducks. The scenes after Crocodile was defeated were also pretty funny. Bon Clay made me laugh a lot too.
But, man, the fights. Sanji's with Bon Clay was the weakest, but it still had some cool animations. The one with that mole and Mr. 5 versus Chopper and Usopp was surprisingly epic. Zoro's against Mr. 1 was unsurprisingly epic. And Nami getting a decent weapon and means to actually fight was something I was anticipating for a
long time, so I was pretty happy to see it happen.
The final confrontation, though. Hahah, oh my God.
Those final minutes of Luffy's fight were absolutely ridiculous. Best use of Dvorak
eeeeeever. Those moments, combined with the rain afterwards... Episode 126 was something else, man.
And now I can't wait to hear Robin's backstory. I already love her.
Just one more thing: really, Pell? Are you really surprised that people thought you were dead after that? I guess Oda doesn't like killing anyone, haha.
