@o-chan:
OP 1- We Are!- Basically encompassed the whole East Blue Saga, remember that moment when it flashed spoilers of the upcoming bad guys/story arcs?
OP 2- Believe- Also has a flash, only it was for the Whiskey Peak saga (and Apis).
Showing flash frames of big bad profile shots doesn't count. The bulk of We Are is just the Straw Hats fighting random pirates and Believe's catch is recaps of the crew's past.
@o-chan:
OP 3- Hikari E- Basically spoiled the twist about Robin joining the crew and was used mainly during the filler portion.
They included Robin in the opening when she joined the crew. Just because they started using it early doesn't matter.
@o-chan:
OP 4- Bon Voyage- Was the FIRST opening to include all the "outside of the Straw Hats" plot elements in the series. The five elder stars, Buggy, Ace, etc.
Profile shots are always there and they still don't count.
@o-chan:
OP 5- Kokoro no Chizu- Foxy/Aokiji/Water 7 spoiler
OP 6- Brand New World- Enies Lobby spoiler
Now those two count. They use footage that directly references events happening that will happen in the show, sometimes even pulling footage directly from the episode.
So for reference…
A quarter second flash of Arlong's mug in We Are: Doesn't Count
Clips from the Davy Back Fight and the Enies Lobby battles: Counts
@o-chan:
OP 7- Crazy Rainbow- Whhheeeeeee. Let's animate colorspreads.
Oh, but Mihawk and Ace were it it! That's totally… spoilers... for... no, it's just like the first four.
@o-chan:
OP 8- Jungle P- The first OP to include the new ship and Franky, and filler arc/Thriller Bark spoilers.
Jungle P is totally about Thriller Bark, so yeah, that one counts.
@o-chan:
OP 9- We Are Remix!- Because it's a reversioning of We Are it does show how far the crew has come and the Oz battle spoilers.
If not for the completely random Oz clip (which I had forgotten about) it wouldn't count.
@o-chan:
OP 10- Share the World- Amazon Lily and Impel Down spoilers
OP 11- Impel Down and Marineford spoilers
yeah, those count.
So yeah, six out of 11, more than I thought (I forgot about the Oz and Imperial down stuff in We Are Remix and the new one), but still far from EVERY.
