post time skip just WCI, the tsunami being the obvious but the cliffhanger with the flag floating in the water was great, dead end musical, that moment was brilliant.
pre time sip, little garden with the wax statues, alabasta when Luffy lost to Croco-boy in the desert, enies lobby, sabaody and impel down
There were actually some dangerous moments in WCI, but since we know that the SH won't be dead, we dont feel the danger that much. Unlike pre ts arcs when the manga was still fresh so it felt more unpredictable.
alabasta when luffy lose 2 times
luffy vs lucci when lucci use rokuogan
impel down when maggelan use is ultimate poison
maybe marineford when akainu chase luffy ... but luffy have lost allies so pretty sure he will save
Wci when was fighting big mom kids while waiting on sanji food, when luffy got KO and was falling of onigashima & when big mom best law and Kidd and was heading towards Kaido but we all knew how that played out
