"Mxy's Mix-Up" is the twenty-ninth episode of the first season of Justice League Action. It is the overall twenty-ninth episode of the series.
As the Justice League tries to protect the United Nations from Grodd's gorilla army, Mr. Mxyptlk pops up from the fifth dimension and thinks it would be great fun to put each of the superheroes' brains into another hero's body.
A flying transport lands outside the United Nations building and Gorilla Grodd with an army of ray-gun-armed gorillas disembarks. Grodd intends to abduct the UN delegates as an initial step in the gorilla conquest of the world. Batman and Superman, accompanied by the novice Stargirl, rush to the rescue. Joyless Batman lectures the young superhero on being efficient and ruthless, but friendly Superman encourages her to relax. As the gorillas scale the UN building, the superheroes intervene and, after a fight, round them up into a makeshift cage of UN flagpoles. Stargirl has to be helped out of a mess by her veteran colleagues.
Then, to greatly complicate matters, the imp Mr Mxyzptlk chooses this moment to pop out from the fifth dimension. Superman states that he will only disappear again if he says his own name backwards. Mxyzptlk is immediately annoyed by Stargirl's inability to recognise him, and when she plays with his name by suggesting he's mixed up he devises a plan for mischief. Releasing the gorillas, he causes the minds of the three superheroes to transfer to each others bodies to mix them up. Although the three realise what has happened to them, they still decide to deal with the gorillas but encounter difficulties with their new circumstances. Stargirl in Superman's body can't control her flight, strength and heat vision; Superman in Batman's body can't work the bat-equipment or get used to not being super; Batman in Stargirl's body has fewer problems.
Gorilla Grodd sees this as an opportunity to crush the Justice League and the battle continues, but the superheroes realise that they can't win and decide instead to deal with Mxyzptlk first. They need backup and Stargirl, for some reason, suggests Firestorm whom she had earlier described as an "atomic guy with two personalities". Batman radios for what he calls "Bravo squad" and asks them to bring Firestorm. Grodd claims victory while his gorillas surround the heroes and prepare to open fire.
Then someone shouts out an insult to Grodd and he turns around to see a crowd of Justice League heroes including the garrulous Firestorm (the others are Flash, Martian Manhunter, Cyborg, Plastic Man, Shazam and Zatanna). Professor Stein admonishes Firestorm for his attention-seeking behaviour. Mr Mxyzptlk responds to this by mixing up their bodies and minds too. This leads to even more chaos for the Justice League and they are no closer to subduing Grodd. But then, as Mxyzptlk laughs uncontrollably, he suddenly hears Professor Stein talking to him as though he's in his head. The spare personality of the Professor has apparently found a new home. The Professor belittles him by suggesting that he has multiple personality disorders and states them as incomprehensible technical terms. Mxyzptlk, repeating back the terms, denies that he has any of these but the last is just his name spelled backwards and so he disappears. The personality transfers caused by him are all now reversed and the Justice League is returned to normal.
Grodd, who thinks he can still win, changes his mind when the League all assemble in front of him and he surrenders.
