Man Comics #1-28 (Dec. 1949 - Sept. 1953).
Bob Brant and the Trouble Shooters. First Appearance: Man Comics #27.
The Trouble Shooters consisted of four boys:
Bob Brant, the blond leader who wears a "B" letter sweater--he's a devoted son but is inquirious, adventurous and two-fisted and would undoubtedly have grown up to become Captain America (I) if the role wasn't already taken. Bob is fearless; where the other Trouble Shooters are frightened at the thought of investigating a haunted museum, Bob dives right in. Bob has a pet raccoon (unnamed) and is around fifteen or sixteen. Bob, like the other Trouble Shooters, is a good fighter, quite capable of taking on and beating Commie agitators, mobsters, and counterfeiters.
Daffy, who is tall, dark-haired and skinny. He always wears a shortsleeved white oxford underneath a sleeveless black sweatervest, and has an unfortune Moe Howard/Guy Gardner haircut. He is Bob's second in command, and seems to get involved in matters either when dared to by Bob or when he's unwilling to let Bob take the lead.
"Feathers," an "Indian" (his origin and why he's hanging with these whiteboys is unexplained) who wears a headband with two red feathers but (oddly, for the stereotype) is very intellectual in manner and speaks like Reed Richards:
"Bomber," who has red hair and is short, scrappy, and not unlike a number of Jack Kirby kid heroes (Scrapper, Brooklyn, etc). Bomber is in a lower grade than the rest of the Trouble Shooters--he is literally half their height and, despite his rodomontade, cannot be more than nine or ten years old.
Two ancillary members of the Trouble Shooters are Carol (the feisty redhead who is Bob's nominal love interest) and Bess, who has green hair (bad coloring mistake, either on Carol's hair stylist or on the colorist of Man Comics) and is Daffy's girl ("Hey, Bess! You're my chick! Remember?"). They're girls, though, so of course they run away in tears and fear when danger presents itself. (Somewhat oddly they aren't used as hostage material, though.)
In three of their stories they fight bad guy counterfeiters dressed up as mummies; Lance has a solo adventure stopping an "atomic pistol" (capable of burning holes through cement and disguised as a toy gun) from being "shipped to the Reds in Korea;" and the Trouble Shooters fight Roger Carstairs, a killer mutant who is one of their schoolmates. In Feathers' words, "Roger is a mutation. A super-being with intellectual powers far beyond present understanding! He belongs in a world 2 centuries from now when mankind has gradually evolved to an advanced condition!" Roger describes himself as "a super being...a new step up in Man's evolution." He has the power to "project mental images and kill from a distance! MY mind can control the minds of others! Make them imagine things that aren't there...things that KILL!" (Roger buys it at the hands and guns of his own hoodlum henchmen.)
