a new report reveals that the upcoming novelisation (which Johnson contributed to) reveals some very interesting details about the character. Apparently, Snoke once connected with a younger Luke Skywalker who was in the process of searching for Jedi lore, something we know is the case after playing the Star Wars Battlefront II video game. It's not clear if this meeting took place in person or via the Force but it reportedly ended up giving Snoke a deep respect for the Jedi Master.
Snoke, meanwhile, was a gifted Force user since a young age and used that to see his dark future, something which presumably turned him against Luke Skywalker (after all, seeing that someone is going to be your enemy down the line is going to make you hate them). This report also claims that Snoke was so powerful that he could conceal his existence from the Emperor and that he used his contingency plan - "Operation Cinder" - to take control of the Empire and make it The First Order.
