Nami-Robin-Yamato(?)
Usopp-Franky
Sanji-Brooke
Zoro, Chopper and Jinbe parallel each other and Zoro foreshadowed them both. Nami foreshadowed and paralleled Robin. Yamato has to parallel Nami and Robin along with being foreshadowed.
°Nami and Robin lived as prisoners even in their own homes. Nami was forced to work for Arlong as too weak to resist. Robin was too weak to resist the WG and literally became a cuffed prisoner; the main motive of Enies Lobby was to find the keys to Robin's cuffs. Yamato was literally introduced as a cuffed prisoner to someone more powerful than her.
°Nami was saved by a marine(Bellemere) and later, a marine(Captain Nezuki was the reason Arlong remained in power). Robin was saved by a Marine(Saul and Aokiji) and later had her home destroyed by the marines. Yamato has nothing to do with marines but its still similar how she has enemy pirates instead of marines.
°Nami and Robin's arcs involved a strict time limit scenario. With Nami, Luffy had to be saved before he drowned(with people holding off Arlong) so he can fight Arlong again. Robin had to be saved before she went to the gates of justice. In Wano, Kaido has to be beaten before Onigashima lands on the capital, Luffy needs to be saved before he drowns and Yamato is holding off Kaido until Luffy comes back.
°For Nami, Robin and Yamato, their arcs contain a weak scumbag(Nezuki, Spandam and Orochi, all being animals btw) backing a man animalistic physical powerhouse who is also the strongest antagonist in Arlong, Lucci and Kaido.
°Nami foreshadowed Robin by wearing her Alabasta outfit in Loguetown. Yamato foreshadowing? Well Momo called Nami a princess and Yamato is the child of a king along being a reference to princesses in old Japanese tales.
