So you thought Jem and the Holograms would just totally ignore the character of Synergy? Nope. You underestimated the filmmakers. Instead, it looks like they’ve kept the concept and taken a massive dump on it, just like everything else.
Synergy’s a tiny robot who projects old home movies as holograms so that Jem can remember that family is important.
Don’t believe me? Watch the new trailer and try not to throw stuff at the screen.
