You want a character that can merge two universes together? Mister Mxyzptlk (DC) aka Impossible Man (Marvel). A Fifth Dimensional being able to manipulate reality as will and canonically can hop between the DC and Marvel universes on a whim. And would probably do it out of amusement or to win a bet.
