That's funny! Nobody answers! Probably no one's home! I can't leave the key out here or someone might walk in! This door has an automatic lock! I'll leave the key inside and close the door behind me when I leave! HEY! What's this? There is somebody home!

Synopsis for Capt. Marvel Jr.: "Capt. Marvel, Jr. Becomes Too Strong!"
Dr. Sivana gets a call from over-eager goons who point he promised they could rob the Sub-Treasury Building that week, but he points out Captain Marvel, Jr. is still around. He goes back to working on a Strength Potion that turns a rheumatic mouse strong enough to fight and kill a tiger in 34 seconds flat. However, he finds this only made the mouse 1,000,000x stronger, upsetting him, since Captain Marvel, Jr. is already stronger than a million men. Instead, he’s inspired to create something to make Captain Marvel, Jr. too strong. His goon shows up to complain about the Sub-Treasury Building and Sivana now cheerily agrees to it. Freddy Freeman is meanwhile peddling papers near the Sub-Treasury Building, since he got word there’d be an attack there and he isn’t sure who would think to tell specifically Freddy to show up there. He soon finds the stick-up starting and calls CAPTAIN MARVEL to become Captain Marvel, Jr. Junior quickly routes the robbery, finding from one of them that Sivana is in charge. Sivana approaches with a derby and a fake beard on it to try to get Junior to try some “Belchi-Cola,” but he declines and Sivana instead gets a job at a restaurant Junior enters, giving him some water that he spiked with Strength Potion. Junior soon finds that his water glass now shatters in his hand, then breaks his table, then steps through the floor. When he tries to fly out, he finds he’s now more dangerous than a missile, wavering too hard to fly easily and also running into walls.
Soon enough, Sivana and his goons plan the Sub-Treasury Building job via using a purple helicopter to case the area. Trying to follow it, Junior flies into space while Sivana sprays knockout gas into the Sub-Treasury Building, but one of the guards manages to lock the gate shut and they find they can’t penetrate it… until Junior crashes into it and tears a hole in it and out the far wall. Junior soon finds that he can’t easily stop himself, so he returns to being Freddy on the city limits. Freddy finds that now he can leap whole buildings in a single bound and suddenly moves in to kick Sivana’s men in the spines and is able to defeat them easily, jumping into their helicopter. However, after a single punch, Sivana smirks that the Strength Potion just wore off and tries to bludgeon Freddy with a wrench, only for him to call CAPTAIN MARVEL so Junior can arrest them easily. Junior points out that he got some assistance from Freddy Freeman. Later, Freddy thinks that Sivana will never reform, but it was fun to have super-powers as Freddy Freeman!

Synopsis for Capt. Marvel Jr.: "Capt. Marvel, Jr. and the Key to the Mystery!"
Freddy Freeman is peddling papers to a man named Mr. Blake, who Freddy thinks he doesn’t know anything about other than his name. Suddenly, a safe being hauled to a high floor snaps and threatens to crush him, so Freddy calls CAPTAIN MARVEL to become Captain Marvel Junior to push it back into place. He returns to being Freddy and finds Mr. Blake dropped a key on the ground and picks it up, heading to his house. He finds his house is quiet and seemingly empty. Finding the door has an automatic lock, he decides to open the door and then leave it inside so it’ll lock closed behind him. When he looks in though, he sees who he thinks Mr. Blake is… but it’s not him… and he’s dead! He finds the place is lavish and amazing and a note from a “Chauncey Tisdale” who is blackmailing Blake for $10,000, more letters from Tisdale and a newspaper that reveals Blake is actually a pseudonym of “Lord Greystack,” an English playboy who killed a man in a drunken brawl and mysteriously “disappeared.” He finds a card on the dead man says that he’s Chauncy Tisdale, only for Lord Greystack to knock him out with a blackjack and starts dumping Tisdale’s body into an incinerator while Freddy wakes up bound and gagged in a corner, until Greystack shoves him in next and starts piling coal atop him. He manages to slip his gag on the hinge of the incinerator and calls CAPTAIN MARVEL to become Junior again and breaks free. Blake destroys all evidence of his former identity and Junior punches him into a wall. Later, a cop tells Junior that Lord Greystack has been extradited to the UK where he’ll face justice after 20 years for murder.

Synopsis for Capt. Marvel Jr.: "Capt. Marvel, Jr. And the 'Poisoned Press'"
One day while peddling papers, Freddy Freeman has a dizzy spell and calls CAPTAIN MARVEL to become Junior rather than keep feeling sick. He finds other people collapsing from vertigo and the cops and ambulances are soon at work, but becoming overloaded. A doctor tells him that these people are anemic and that it’s as if each person were starving for a week! Junior is puzzled until there’s a robbery on the North side of town run by known gangster “Looter” Luke. He starts off casually by bragging how easy it is after starting this epidemic until Junior starts to fly in and clean house quite severely. Luke finds that even his biggest goon, Oxie, is only confident he can last maybe ten seconds, which is enough for him escape. Oxie is dazed, but tries to fight back, so Junior feigns that he’s losing strength to let him get away and follow him. They plan on pulling another, similar job. Junior, looking in, finds that they’re working with Lester Larch, an inker and dyemixer at the newspaper plant. Oxie manages to hit the lights after Junior charges in to clean house and most of them escape. He soon flies off to the plant and finds Larch sneaking something with heavy gloves into the ink for the morning edition, which is giving people anemia! Larch whips a bottle of ink in his face, forcing Junior to let him go until he can clean his face off. He takes the bottle he emptied into the ink and finds from a chemist that it’s basically radioactive. He flies off to Larch’s house and returns to being Freddy so he can make sure the whole gang is together. As it turns out, they are, but a goon catches Freddy and drags him into the house. Larch has him tied up and reveals his new toxic ink also makes people blind temporarily. They try to test his eyesight, but when they remove his gag so he can answer them, he calls CAPTAIN MARVEL to become Junior. Junior soon clean house and arrests them all, revealing to the police that the radioactive paper releases deadly gamma rays. Later, Freddy sells a fresh paper that doesn’t poison people.
