What happens to the gigantic monsters from arcade classic Rampage after they've transformed back into their unclothed human selves? That all depends on what sort of naked human you revert into.
I remember playing Rampage in the arcades as a young man and feeling just the briefest wave of titillation as Lizzie reverted to her naked blonde form. Nowadays I can't do an internet search without seeing a nude woman, but back then this was what counted as exciting. Apparently I'm not the only one that thinks so.
