10. The T-800 Is Now A "Loveable Oaf"
It's common knowledge that in this timeline, the T-800 brought Sarah Connor up and is referred to by her as "Pop". That's a pretty drastic change for the character played by Arnold Schwarzenegger, and there have been tons of rumours about his new personality. Unfortunately, none of them have been particularly good. The Terminator has apparently developed feelings, and Kyle Reese is actually told off by Sarah for hurting them at one point in the movie. Terminator Genisys simply won't feature the badass T-800 fans know and love, as he's been dramatically toned down and is now being described as a "loveable oaf". There have also been some very vague reports about some sort of twist involving the character though, something which has led to many fans speculating that he'll be revealed as having been a bad guy all along. Either way, it's going to be a very different T-800.
