Retaining the functions from each power, you now have a “phone book” containing a person’s psyche and memories, capable of manipulating them to the point of melding them into a gestalt of multiple people; this has a peculiar effect on their existent powers, synthesizing into a power made from a sum of their parts, possibly shape how it’s expressed by editing the person or gestalt’s recollection of their Trigger Event.
You can overwrite others with a person or gestalt of your choosing by physical touch.
