Check this out (and remember I told you it possibly spoils the movie):

As per the latest trailer, it does look like the Robotniks are going to team-up and betray Sonic in the movie. Though it can be expected for a character like Robotnik, you would think that him teaming up with Sonic was pushing the point of how dangerous Shadow is going to be.

Admittedly, Shadow is considered more of an antihero, so maybe the movie is just confirming to the fans that he won’t be the ultimate villain in the film; but then again that kind of spoils his arc in Sonic 3. By the looks of it, it’s just going to be another Knuckles story where Sonic and Shadow fight, realize they’re not so different, and team-up to fight Robotnik.

Then again, this is just a kids’ franchise, so we shouldn’t expect anything like Lord of the Rings when it comes to plot. Either way, a lot of fans are happy to see Shadow finally make it to the big screen, and the movie promises to deliver everything that made the character popular—like shadow using a motorcycle and guns.
