I forgot even Robin can get into the Oda Shock face

She's normally so chill

Indeed. It takes a lot to get to her

Hell Nami react so much more then Robin does

I can't remember what caused her to do this

I think that's like the only one she's done ROFL Unless I am mistaken.

it probably is the only one she has done... though maybe she reacted when they were falling off skypeia at the end of the arc

ok just checked, nope you don't see her freaking out there

so yeah this was the only time she reacted as such

vignette4.wikia.nocookie.net/onepiece/images/2/2c/Usopp_Robin_and_Franky_Shocked.png/revision/20140907180547 now in anime form

it was when the dwarfs said they were going to attack Don, and I think all 3 of them were shocked at how wrong they were

in terms of judging the dwarfs
