Amazingly, Star Wars 7: The Force Awakens has only been out for a month, and it's already made the kind of money that studio execs dream of, and rightly so. The film is just flat out amazing. Great action sequences, a perfect blend of classic characters as well as interesting new ones, and a surprising amount of humor and homages to the previous films. The movie seems to have a little bit of everything, including plenty of speculation about what's to come.
Of all the speculation, the one that most fascinates me is the theory that Supreme Leader Snoke is in fact Darth Plagueis, who was the master of Darth Sidious before being murdered by him. Despite not being heavily mentioned throughout the saga, Plagueis was essentially the biggest bad of them all, at least as far as the original EU was concerned. It was his experiments on creating life that resulted in Anakin's birth, making him solely responsible for nearly all of the Star Wars saga. Pretty epic claim to fame for a guy that got mentioned just one time in the whole series.
While he appears to be pushing daisies now, I'm certainly holding out for Plagueis to be revived and thrusted into the spotlight. Here are a few reasons why I think Snoke turning out to be Plagueis would be a great move for the Star Wars saga.
Plagueis could pick up right were he left off, and his motives would justify his lack of prominence
In creating Anakin, Plagueis' goal was to control him and use him as a tool to destroy the Jedi, fulfilling the will of Darth Bane. His desire to fulfill Bane's will could be seen as a reason for him never revealing himself until up to this point. He perhaps did not care who destroyed the Jedi, as long as it was done, and did not want to upset the course of action by revealing himself and creating a power struggle. Also the Sith have a history of betraying their masters, so he may have seen Palpatine's betrayal as a sort of "rite of passage/surpassing the mentor" type of thing. (Famous Example: As part of his training, Darth Sidious purposefully enraged Darth Maul into attacking him) Should they retcon Plagueis' death, he could pick up (almost) right where Palpatine (and he himself) left off. By controlling Kylo Ren, Plagueis would once again have the incredible powers of the Skywalker dynasty under Sith control, which leads into
Plagueis is the perfect person to continue the theme of the saga
The story of Star Wars is all about the tragedy of Darth Vader. That was the reason George Lucas never made Episodes VII-IX himself. He said he "couldn't think of anything" but thankfully someone else did, and I think it worked out perfectly. Kylo Ren being not only obsessed with Darth Vader, but also his Grandson is, in my opinion, a great way to carry on theme "tragedy of Vader" theme. As Plagueis was the creator of Anakin, it would make sense for him to still be interested in the Skywalker line. His control of Kylo Ren is merely an extension of control of Anakin, helping to further the Chosen One's story. And should the trilogy end with Plagueis' death, would be a fulfilling ending to the Star Wars saga. The Skywalker family would forever be safe, as the ones who wished to abuse their power would be destroyed forever
Snoke would help tie in the Sequel Trilogy with the (groan) Prequel Trilogy
I'm sure we'd all be fine if we never had to speak of the Prequel Trilogy again (except for Darth Maul, who doesn't love Darth Maul?) but I feel that tying in with it is an important thing for a series such as this. Take a look back at the Original Trilogy. It's packed with mentions of the events of the Prequels. It helps to both create a feeling of continuity, as well as highlight the importance of the events of those films. The Force Awakens had tons of references to the Original Trilogy, but only a single reference to the Prequels. I'm not sure how many we'll get in the next two, but I'm hoping for a greater deal of them, and Darth Plagueis would be the mother of all references. He would help to bookend the entire trilogy: the villain who started it all would be there to end it all.
All of this is, of course, fanatic speculation. Snoke could be just about anyone. Even a new character! I guess we'll just have to wait and see.
Star Wars Episode 7 is scheduled for release on Dec. 15, 2017, and it can't get here soon enough.
