Eh, I might as well share ideas for episodes I made in my free time.
>Frightful Fights - Batman teams up with the Creature Commandos to take down Scarecrow and stop him from making it Halloween night forever.
>Attack of The Ambush Bug - Ambush Bug invades the world of Justice League Action to give it a review and when it falls short on his standards, he decides to change it to something more of his liking, which in turn, annoys the wits out of the Justice League
>Play Date 2: Turbo Edition - Toyman returns and this time, is teamed-up with Batman’s own maturity-challenged enemy Baby Doll! Who take control over multiple Justice League members and use them as new characters in their own twisted version of Boulevard Brawler 2: Turbo and the only one who can save the Justice League now is… The Joker!?
>Dead and Loving It - Boston Brand, now resurrected as the new Deadman, now has a clean-slate on his destiny, which means Specter is assigned to guide him on the path of using his powers for fighting the forces of evil but Deadman is tempted to use his new abilities to exact revenge on the man who killed him.
>Mud in Your Clayface - Every version of Clayface combine forces (literally) and overrun Gotham City as a giant clay monster and it’s up to the combined efforts of Batman, Fire & Ice and Martian Manhunter to stop them.
>Plastic-Man Vs. The World - Felix Faust brainwashes the entire Justice League to become his slaves, except for Plastic-Man who know has to take on the World's Finest and find a way to snap them out of it.
