Palpatine can actually use red force lightning, I didn’t just randomly suggest it for the sake of referencing Mortis. We just haven’t seen him use it in live action yet.
When have we seen him use it? Is this from the legends/old EU that said force lightning came from squeezing random fruits?
No idea what is and isn’t canon anymore, When I do personnel cut of film will likely have red force lightning but would mainly just be ascendant with a few added things, still don’t get why people are adding trailer music over Rey v Kylo DS fight seems very out of place.
