10. Newt's Dragon
When he's asked what he did during the Great War by Kowalski, Newt says he was working on the Eastern Front with dragons. Does that mean he was fighting in some secret war campaign? If so, that needs to be a film immediately.
Anyway, the specific dragon that he mentions is the Ukranian Ironbelly, an important breed in Harry Potter lore. It's this creature that guards the bowels of Gringotts and the Lestrange vault in The Deathly Hallows.
Maybe Leda Lestrange will be the one to help capture the dragon using her relationship with Newt? Or maybe the choice is specifically her pining for him.
