Proxy doesn’t actually use the standard Force rules. He’s using technology that simulates the Force, and he knows it. Others, like Darth Vader, can control him remotely and mostly do things as if they were present themselves, or they can be simulated in software.But at no time does Proxy actually use the standard Force rules.This is Proxy from the Force Unleashed. Give him a lightsaber and a holoprojector skin and ta da! Proxy. This is already kinda an in-universe thing. Not that I'm recommending it or that I'd accept it at my table (droids have never gone over well with my group ever for entirely unrelated reasons), but it's your table and such a thing has appeared in Star Wars.
I never played Force Unleashed, but looking g it up... I mean if Proxy had used "telekinesis" or lightning, etc, and you wanted to stat him in the game, it makes sense to start with a droid, then buy Force Powers. Then, with Move, just call it Gravity Beam or whatever, and claim he's using a micro tractor beam or something.
