What do you guys think will be some additional ability the other gorosei will have? Nasujuro and Warcury are obscure in terms of google results but we have seen Nasujuro use freezing powers similar to Brook. Saturn those weird powers related to his gaze.
Bakotsu/Hakkotsu no Uma = It's immortal/undead and can bring bad luck in yokai lore, and according to lore, only one existed and it terrorized the town of Fujikawa. In the chapter it also has icy underworld powers just like Brook and it may be based on Hakotsu's ability to curse the crops of farmers who didn't feed it while it was alive.
Itsumade = Associated with plague and screams its own name real loud which means "Until when?" and it appears where there's lot of death in yokai lore. Probably has sound and disease-based abilites.
Sandworm = Some giant worms in folk lore say they could eat anything and get bigger with every feeding, like Haftvad's worm and Peter fights by eating as seen with Luffy. There's also the Skolex worm that was also a big eater and it could swim in water without a problem. Mongolian death worms can kill on contact. Probably has earth or sand-based abilities too, and maybe something relating to stomach acid I guess.
Houki the Silly Piggy = Its mostly a Chinese monster and it was unique because it was insanely huge, had a mouth full of spikes made of metal, it could grow a second head, one on each end of its body, and it could change its appearance. According to its lore, it was defeated by a sharpshooting marksman, so he may be Usopp or the Weakling Trio's opponent. This pig really loved mulberries.
Ushi-Oni = Most people here already know, but according to yokai-lore these guys, aside from their poisonous venom, also liked the sea and feasted on sailors who crashed their ships at the coast and they also were associated with snake women. And if the Gorosei really arent devil fruit users, Saturn may have some unseen influence over the sea or can summon snake beings.
