Force ghosts

That's an interesting idea. If they were added, I wouldn't think they could be used in a squad, but more of a boost for specific Jedi. Ben/Yoda for Luke, Anakin for Ahsoka, Qui-Gonn for Ben, etc. If they were added, what kind of utility would you give them?

The green goblin would have a great ability to set fires to things

Good question…,foresight would have to be in there I reckon,the only only other interaction I can think of is when yoda moved red one out of the swamp in empire strikes back and Luke did the same in the rise of skywalker.i think cg would make  lot of profit if they were to be future conquest characters

but yes I think those characters that you mentioned their kit could also be updated for force ghosts

Those weren't Force Ghosts though. Force Ghosts can't physically interact with objects. They're more like spiritual guides.

It's an interesting idea. Appreciate you sharing your thoughts with us!

In Rise of Skywalker it was a force ghost of Luke. But in Empire that’s correct. Luke’s ghost also caught Rey’s lightsaber when she tried to burn it. I love the idea tho. Maybe as a summoned character when certain squads are built in a way

If force ghost can't effect the physical world then how did Yoda call a lighting bolt to burn a tree/temple in his last appearance? 

True! He also smacks Luke with his cane. So, I stand corrected. It would be pretty cool to have him summon lightning as an AOE or maybe stun with his cane. Apologies for my misremembering of that scene. I'm not recalling another time where a Force ghost was able to do that as they are normally just advising. I also have not read every book/comic so there could be other examples where they physically interacted.

I stand corrected too because yoda was still alive in empire strikes back when he pulled red one out the swamp…..we need force ghosts tho :-)
