Superman Vs. The United Federation of Planets
Q and Mxy run into each other while dimension hopping. A fight ensues and neither one can get the upperhand. Q suggests that they settle their dispute in a more civilized manner, and choose representatives to fight for them, the loser having dominion over the others respective reality. Mxy agrees, but stipulates that you can only choose one representative. Q reluctantly agrees, and as he does, Mxy laughs hysterically and says "I choose Superman!!!". Q then states "Well, I choose The Federation". Mxy then argues that he'd stipulated that either could only have one representative, and Q counters that Mxy never stipulated that the one representative had to be an individual being, and that the Federation is one organization, so therefore within the rules. Mxy is angered, but he has faith in Big Blue, and says "Fine, Supes versus your 'Federation' it is. I'm going to love ruling your dimension for eternity". Mxy and Q shake hands, and then Superman is teleported to the Star Trek Universe. Mxy explains to Supes that if he doesn't defeat the Federation that Q will be able to destroy the DCU. Q teleports to the bridge of the Enterprise in front of Captain Picard and tells him of the wager he's made with Mxy and the stakes, and Picard sends out a subspace distress signal calling for all member planets and allies of the Federation to arms to defend their universe against the impending takeover.
