One piece way of milking a plot that is heavily forshadowed to happen inside the same limited arc is just too much lol.
How many times we're getting "Onigashima almost reaches the flower capital", i think that span over 30 chap at least.
It took about a year the AR woke up again for 3rd time which i hope it finally do something worth.
And let's hope 8 minutes of Vegapunk announcement won't span over 20 chaps again.
He fought them; but none were defeated by him is the point.

WCI and Ennies Lobby off the top of my head

Lucci got Ko'd, and Kizaru got paralyzed. If you mean "permanent," then yes, no one is defeated. I dont. Luffy shat on both Kizaru and Lucci even saturn if it wasnt for regen thats WAY more than enough for me.

They both were saving arcs, but they turned into running midway/end. I wouldn't say they were exactly escaping arcs. This is the only arc that comes to mind as my sole escape.

I mean, if you look at Ennies Lobby as escape arc, then so is the Sky Island arc because they run after finishing the arc. Again, I don't count 5 chapters trying to escape as an escape arc.
