I am curious if there is a trope about people who gain superpowers by being in another world but none while back in the real world.
Examples would be Twelve Forever where the 3 kids go to a place called Endless Island where they gain a different appearance and unique powers. Persona 3 to 5 seems to follow with how they can summon Personas but the Midnight Hour may be seen as a displacement of time rather than another world. The Manfra Dreamland has people who have overcome their fears and become Travelers with their power based on their fear.
