It's only Robin, Franky and Brook pre-TS that is missing from GB2. And that's cus they were too lazy to put them in the first game.
And that's why I worry. Gigant Battle 1 already had the 6 pre-TS Strawhats. This being the first of a series, and them already using the New World, I'm expecting a limited amount of pre-TS Strawhats.
