Action League Now!

Thundergirl, while secretly taking photos of The Mayor's illegal weaponry, is captured and placed in a cage. It’s up to the rest of the Action League to rescue her, but, per usual, they screw up, ending up in the cage along with her. After a dumb bet placed by Meltman, The Mayor proceeds to press a button that sets off a rocket scheduled to blow up the capital.

A local swimming pool run by The Mayor seems to be causing some trouble lately. Once the Action League get to the scene to investigate, they find that a large trophy bass thought to be extinct is the cause of it all, chomping down swimmers and dismembering them. Bill the Lab Guy warns the League of the rarity and elegance of the sea creature, but Stinky Diver has other plans in mind.

A number of suspicious packages are sent to the Action Headquarters, and once they’re opened, they combine to form Hodge Podge, the former accountant for the Action League who was disfigured and put back together (poorly) after a blender accident. This maniacal madman is out for revenge, and nobody can stop him! (First appearance of Hodge Podge.)

After drinking an unfinished chemical in Bill the Lab Guy’s laboratory, Meltman suddenly turns into a giant. Changing his name to Mega Meltman, he soon finds out that his large stature is making things harder for himself and the rest of the Action League to cope with. However, in the end, this increase in size may help out a group of young kids who are trapped on top of a large tree. Near the end of the episode, Bill the Lab Guy wanted to tell Meltman that the drug was temporary. However, Meltman refused to listen and he shrunk, causing him to fly away.

llegal nuclear activities by The Mayor place Quarky the Lab Girl in danger, as she gets infected and later gains superpowers from the effects. Thus, Super Teen is born! Will the Action League be able to get things in order, or is it up to the father-daughter team of Quarky and Bill the Lab Guy to solve the problem at hand? (First appearance of Quarky the Lab Girl.)

Peaceful aliens land on Earth and ask to learn about the way Earthlings function. Unfortunately for them, the Action League are assigned as Earth's representatives. As expected, just about everything goes wrong (aliens getting melted, electrocuted, and liquefied, among other things), and the extraterrestrials soon change their minds about giving peace a chance.

The Mayor invites the Action League to his home for a Thanksgiving dinner, and Stinky Diver is the only one to think twice about the situation. After Justice lets Stinky know of the League's situation, it’s up to him to save his colleagues from escaping the inside of a hollowed-out turkey in the midst being cooked in an oven. (First appearances of Stinky Diver's mother; second appearance of Stench Diver; First appearance of Stinky Diver's Father.)

After reuniting with his long-lost "parents" on popular television program Lola, The Flesh is asked by them to carry heavy objects from an empty building into their car. At first, the Action League are jealous of the airtime Flesh is getting, but they soon discover that he has been lied to and needs to be stopped.

There’s a new group of superheroes in town, and they're called the Danger Society! After saving The Chief at an annual company picnic, they begin to take over every task that the Action League used to fail at. Before long, the Society replaces the League completely, leaving them out of work. In the end, the only way to decide who gets to stay in town is by seeing which team can save a bus full of schoolchildren first.

A mysterious liquid is squirted onto Thundergirl by The Mayor in a sabotage attempt, resulting in her losing the ability to fly. Once the Action League find out that he has two children kidnapped in a birdhouse, only the power of flight can save them, so the League gets to work—using balloons and a slingshot, among other devices, to try to get Thundergirl airborne.

The Mayor’s son gets stuck in a kitchen sink during an exploration, and it’s up to the Action League to save him. However, the League's ineptitude at such tasks proves to be an obstacle, with Thundergirl and Stinky Diver spending much of the episode stuck to an active ceiling fan. Can they rescue the victim before time runs out?

Loud clog-dancing by Meltman (in midst of a celebration to honor the Action League) goes wrong when it wakes up Spotzilla, a Mesozoic creature that runs rampant upon awakening. After it eats up Stinky Diver during a televised interview, the League realize that they must act fast to rescue one of their own.

There’s a new superheroine in town, and her name is Lightning Lady! She wastes no time in getting herself inducted into the Action League and garnering much (male) attention, leaving Thundergirl jealous. Is everything about Lightning Lady crystal clear, or is there more to this mysterious "woman" than once thought?

Meltman loses his memory after a life-size phone lands on him during a mission to steal a secret formula from The Mayor’s office. The Action League—with help from Bill the Lab Guy—must try their best to bring him back to his previous state.
