Fallen Anakin Hero's Journey

I’ve always hated the fallen Anakin idea. I’m aware other characters were on screen for as much or less time than him, but those characters still have some sort of plausible synergy with their faction (Veers, Starck, etc.). Fallen Anakin was a plot device, a means to an end, which is Vader.

Only way I’ll accept a fallen Anakin is if they give GK an insta-dismember ability against him.
