They are insecure cause Morj reminded them who the main 3 are.
Thats why they keep going om about the monster trio that has nothing to do with it they know deep down its true.
"Luffy Zoro and Nami are the trigger to one piece" Oda after Usopp and Sanji had already joined the crew
LOL, Morj's video is bs to be honest, pre ts I agree with his points, post ts the dude was stretching more than luffy, straight up taking things out of their context and ignoring everything sanji did pre and post ts
Nami literally said they are the curly hat pirates after the crew separated, she acknowledged sanji as the captain in luffy and zoro's absence
Any one who's been paying attention to post ts would know that sanji's been driving the plot forward more times than Nami
Heck oda even gave him more panel time than zoro lol
Pre ts the main characters were obviously luffy zoro nami
Post ts it's been luffy zoro sanji, Nami is really close but she didn't impact post ts as much as one of these three
