Yes, but there's nothing that suggests that these three have some sort of dream of their own, which has, up till now, been revealed during a member's past.
Oda's flashbacks are not uniform. For example, Brooks was the last three chapters of the Thriller Bark Arc and Robins was during the Ennies Lobby Arc (four arcs after she joined the Strawhats). We also didn't know Nami's goal or Choppers goal until after they joined. Franky, Brook and Robin didn't even talk about their dreams until the very end of an arc.
Viola - Based on Violet Gibson
- Assassins, known for shooting Benito Mussolini (Doflamingo?)
- Viola could be a lookout, a position yet to be filled in
- She has already hinted that she wants to leave Dressrosa
- Sanji offered her to join them, she refused only because she "had business to take care of", much alike Jinbei who will almost certainly join them
-We already know of her dismal past
-She has bonded closely with Sanji, Zoro and Luffy -
THE MONSTER TRIO, just about seals the deal really
Kyros - Based on Cyrus the great
- Great colosseum heroes come criminals after retiring from being a Gladiator, Cyrus also used to be a Roman General
- Unsure of a role in the crew right now, although he doesn't necessarily need one that functions on the ship (like Robin or Zoro)
- He has bonded closely with Luffy, Zoro, Usopp, Robin and Franky
- He has also had a horrific last ten years of his life
- However, he is heir to the Dressrosa throne, so he might not leave
Barolomeo - Based on Alice Cooper
- Famous for disruptive and mocking behaviour (similar appearance as well)
- Could be the "protector of the ship", with his barriers blocking all cannonfire
- He admires the Strawhats,
he dreams of joining them
- He has met all of the Strawhats currently on the Island (and allies + Sabo)
- Having lived in slums for all of his life, he must have had a sad back story yet to be fully revealed
- His Pirate crew don't seem to be very important at all, only showing Gambia on three pages, he could easily leave them for the Strawhats anyday
