Who is Kylo Ren? Let the speculation begin!

Entertainment weekly kicked off speculation on the origin of the new villain in The Force Awakens movie, Kylo Ren. The magazine hints that Ren is not his real name and that “we may soon find out who his parents are”.

Ew.com says that Ren seems to be a “Vader obsessive, with an appearance influenced by that dark lord of the Sith who met his demise long before Ren’s birth”.

So here is my speculation of what Kylo Ren might be.

Is Kylo Ren the son of Emperor Palpatine (a.k.a Darth Sidious)? After all who killed the Emperor? That would be an obvious reason for his Vader obsession and that can explain why he’s after Luke and Leia because they are Vader’s (Anakin’s) children.
Could Ren be the child of either Luke or Leia? If Luke is his dad, there could be some classic father/son issues-there is a familiar George Lucas pattern of son vs. father. If he is Han & Leia’s child, he might be rebelling (no pun intended) against his parents’ politics.
Finally, he might be the offspring of a high-ranking Imperial leader. His obsession could be similar to #1 above.
