Sooooooo when you go to Olympus Coliseum in this game, Herc's all grown up and buff and schtuff. But in BBS, he's Young Herc. If Unchained is before BBS... What's the deal here? Do I need to keep playing to get the answer? Please and thanks fellow Keyblade Wielders. 

The worlds from UX and X are not real, they're illusions pulled from the future by the Book of Prophecy.

Thaaaaaaank you, as expected, I should have just kept playing.

Yep, it's like Robbie stated, because you see, the Book Of Prophecies can be able to project illusions of worlds that are far into the future, and as such, who knows just how far this book can project illusions from, ya know?  But yeah, Herc looking all buff is a result of the book channeling the illusion of Olympus Coliseum from further ahead into the future, ya know?

I alos had this issue. I was super confused until I googled it. Kinda really makes the worlds really meaningless
