Synopsis for Capt. Marvel, Jr.: "Capt. Marvel, Jr. and The Hammer That Shook the World!"
Freddy Freeman is peddling papers at his Newsstand when thousands of dollars float down from the sky! To stop people from fighting each other he calls CAPTAIN MARVEL to start clearing house of the mob as Captain Marvel, Jr. and then flies at top speed to create a tornado that rides all the money into a big pile for him to carry. The man who dropped the money soon announces from his helicopter that everyone is going to die in an hour and they’ll have no time to spend such money. Junior decides he should at least return his money and finds that it’s famed scientist Jethro Dem. He follows him as Jethro hides his nephew and niece, Willard and Marian, into an underground bunker and tells Junior that his hammer is going to strike in a half-hour and also to get out. Junior drops his money on the floor and leaves, then returns to being Freddy to sneak into his window to find that he’s building some kind of doomsday hammer that will cause catastrophic planetary damage… before Jethro brains him with a vase and says that society will be improved by his hammer and it will create a “perfect civilization.”
Suddenly, at a secret spot on the Equator, the Hammer of Jethro Dem strikes and buildings crumble, rivers are wrenched into floods, a mountain falls over, mines collapses, windstorms start everywhere and Jethro legs it to his shelter as Freddy manages to call CAPTAIN MARVEL to become Captain Marvel, Jr. once more. Soon, the Dems emerge from their shelter and Junior denounces him for killing billions and wiping out all of humanity, before Junior flies them away from an incoming tidal wave. They retire to a tall volcano where Jethro is upset that now he can’t build a new scientific civilization that he kept lots of blueprints for and Marian falls into a volcano. Willard tries to jump in after her and Junior is forced to fly Jethro to safety. Becoming the last man alive in the world, Jethro begins to laugh madly as Junior finds the world is slowly reverting to the way it was millions of years ago. However, all this ranting of Jethro is actually all in his head! He soon says that to a bound and gagged Freddy in a chair nearby that the Hammer is going to strike in two minutes and the new world will slowly fall apart like he’s just described. Willard comes upstairs to find his uncle shouting at a restrained child and frees Freddy, who calls CAPTAIN MARVEL to punch out Junior as Captain Marvel, Jr. and takes the shock of the Hammer on his chest to let it destroy itself. Later, Freddy notes that Jethro is in an asylum now, but Willard is a progressive scientist and all his blueprints are helping the scientific community.

Synopsis for Capt. Marvel, Jr.: "Capt. Marvel, Jr. Meets Professor Werewolf!"
Prof. Ichabod Lupus is teaching a course on medieval legend at Dale College nd insists that werewolves definitely aren’t real, which Dean Lawmiss liked so much that he’s willing to make him Assistant Dean! Outside though, Lupus’ rival and evil bald man Oscar Erkardt hears it and decides to sabotage him somehow. He soon finds in an ancient book called The Werewolf Strain (which is somehow in Latin) tells him of a singular family of naturally occurring werewolves… The Lupus Family! Thus, he writes a magic word on Lupus’ blackboard, SOKARKA which, when Prof. Lupus says it, turns him into a werewolf! Heading to work through campus, Freddy Freeman hears the screams of people reacting to Lupus turning into a wolf-man and calls CAPTAIN MARVEL to become Captain Marvel, Jr. Junior wrenches the clothes off of Prof. Lupus, thinking that it’s just a prank of someone putting a wolf in human clothes as Prof. Lupus finds he can’t talk to turn back. Another student gets confused and jumps out a window thinking the wolf is coming for him. When Junior pushes him back into his classroom window, he finds Prof. Lupus is gone.
Soon, Prof. Lupus manages to say SOKARKA as a wolf and turns back to normal and manages to even play it off as some kind of joke with the Dean. Prof. Erkardt decides to find another means to discredit him and releases a real wolf near his house to attack the Dean’s daughter. Luckily, Junior arrives to punch the wolf in the face and says he’ll send someone from the zoo to retrieve it. Soon enough, Junior visits Prof. Lupus, who tells him the truth and Junior assures him that they’ll have to figure this out with science! Junior uses the Wisdom of Solomon to figure out how to make a cure for werewolfism and Prof. Lupus finds he can call SOKARKA whenever he wants now. The next day, the Dean offers the Assistant Dean spot to Prof. Erkardt, only for Prof. Erkardt to see someone enter that looks like a werewolf and says he’s going to admit everything he’s done. Freddy removes the mask he’s wearing, revealing this was a sting and Prof. Lupus calls SOKARKA which does nothing. This convinces the Dean that Prof. Erkardt is crazy and Freddy drags the evil professor to the police.

They soon take a plane, a train and a car to get out to a western vacation in the former ghost town of Crooked Creek. Suddenly, a man fires two guns in the air to stop their car and says that Mayor J Brand of Crooked Creek Territory doesn’t allow cars, planes, radio, telephones, roller skates or Easterners and tells them to take the stagecoach into town instead. On the way there, Crumpet explains that Brand got rich after hitting oil and decided to make his own Old West town and made himself Mayor of it. They find that there’s bandits outside, which Crumpet assumes are just part of the experience… until real bullets fly into their stagecoach and Freddy calls CAPTAIN MARVEL to become Captain Marvel, Jr. to confront the leader of the outlaws, “Black” Mack. Finding that they can’t intimidate the World’s Mightiest Boy, they instead fire at some horses to make them stampede that Junior ends up calming down. He returns to being Freddy to ride into Crooked Creek and stop near the bank, finding they don’t have a Sheriff yet… only Mayor Brand, who won’t let in airplanes to search for Black Mack’s hideout in the caves. They assemble a posse of elderly men which Freddy offers to join. The elderly cowboys are of little help and Black Mack soon tries to attack them, Freddy is shot and knocked from his horse as the outlaws kidnap Mayor Brand. Freddy wakes up, finding he’s only been grazed and calls CAPTAIN MARVEL to follow their trail. Junior lunges at one of Mack’s men when he tries to put a gun to Mayor Brand’s head and manages to fly into a cloud and shoot the gun out of Black Mack’s hand from afar and then quickly punches out him and his gang.

Synopsis for Capt. Marvel, Jr.: "Capt. Marvel, Jr. and Crime's Trumpeter"
Jazzbo is a known gangster who loves playing loud jazz on his trumpet. His goon Louie arrives and says that he’s the only one who made it back from the Fur Loft job, since Captain Marvel, Jr. was there. Jazzbo orders his men to take the fall for him while he gets away and scarpers to the fire escape. The goons are no match for the World’s Mightiest Boy, with Louie fainting. Jazzbo goes to an antique store to feel a little better about being a wanted criminal and having all his ill-gotten gains in that safe in his apartment he now can’t go back to. He finds that there’s an old man offering him the Horn Blown at Jericho, but warns that he can only use it for himself three times and using it more would be “unpleasant” in the results, but is otherwise free. Jazzbo is more than fine with the terms and leaves to play it once in the park, which has a special magic that makes Captain Marvel, Jr. decide not to arrest him, unsure and doubtful about it enough that he’s driven to tears. Jazzbo runs off when he realizes that Junior is right behind him and Junior soon feels better once he’s gone.
Jazzbo soon heads to get a job working in the orchestra of Les B Bopp, who is going to do a big Charity Carnival at the Hotel Ambassador, then hits a solo that is so beautiful that everyone starts laughing madly and collapsing until Jazzbo snatches all their jewelry. Outside, Freddy hears them from some blocks away, laughing for an uncomfortably long time and calls CAPTAIN MARVEL to see what’s wrong as Jazzbo runs with a violin case full of valuables as a butler points him out. Junior catches up to Jazzbo, who plays his final song on the Trumpet, which summons the magic lightning, turning Captain Marvel, Jr. back into Freddy! He clubs him in the face with the Trumpet and captures him, leaving him bound and gagged on stage at an abandoned theater. He decides to play him a funeral march on the Trumpet, using a forbidden fourth time, which makes the whole abandoned theater collapse while a brick lands on Freddy’s bonds, breaking them off so he can slip his gag and call CAPTAIN MARVEL one more time. He soon finds that Jazzbo was crushed to death in all this and outside… finds it was the Jericho Theater!
