[DBZ] When 2 Characters fuse, do they also share memories?
gpt
Yes. They share memories, powers, and even their personalities blend together. We see this a bit when Super Buu fuses with Piccolo, he obtains his intellect and strategies, as well as techniques. Although that isn't a true "merger" so much as a possession, the same principals apply for Gotenks and Vegeto/Gogeta.
