Rebels

The Clone Wars was much much better than the prequels. In fact most of the character designs in SWGOH are based off Clone Wars (i.e. Anakin, Sidious, most bounty hunters, and pretty much every Jedi). I can't think of a single character in this game that was created from the prequels since they were all in The Clone Wars series.

I haven't seen Rebels yet since I don't waste my money on cable so I don't really know the characters.
