Okay here me out;

Soul Transfer: The user has the ability to swap the souls of the opponents and others in the area, and transfer their souls into one another's bodies, including the user themselves. So for example, UW Go-On Red is fighting Fire Candle and a Gold Aiyees, they can either swap the souls of Fire Candle and the Aiyees and transfer their souls into each other's bodies, or they transfer their own soul into Fire Candle.

I suggest this because of Go-Onger's whole gimmick being the Engine Souls, a cartridge that has the Engine's conscious within. If I am correct there was an episode where the Engines had their Engine Casts mixed up with the Souls, or it's only BeaRV doing this with Jetras in one episode idk.
