Red Rube was a moderately short-lived character published in Zip Comics #39–47 from MLJ Magazines (now Archie comics). His origin was similar to Captain Marvel's.
Reuben Reuben was an orphan who ran away from the orphanage and hid out in a castle on top of a nearby hill. There he encountered an old man who gave him a magic elixir that put him in touch with his ancestors all of whom were also named Reuben Reuben. Each Relative gave him an aspect of their greatness, together it made him superhuman.
Calling out the traditional carny war-cry of "Hey Rube!", young Reuben transformed into the adult Red Rube. Eventually, Rueben became a cub reporter for the Daily Sun.
Ruby Red was created in the Shield G-Man Club group on Facebook where people started out by suggesting that since he was something of a Captain Marvel homage, he ought to have a Red Rube family with Red Rabbit and an equivalent of Mary Marvel. The fact that Rube's costume is topless led to speculation as to what "Mary's" would look like. rikoffenberger
wrote something about her crossing her arms a lot. I couldn't resist, and created the topless "Ruby Red" HeroMachine image, and then one that was a little more Comics Code-approriate, and a backstory, to wit:
Rachel "Ruby" Reuben is Reuben Reuben's little sister. They ended up in different orphanages. One day, she happened upon the scene as a bunch of bad guys were sneaking up on Red Rube in an alley, where he'd just defeated one of their number.
Thinking to warn him, Ruby called out to him, "Hey, Rube!" Since she shared his genetic heritage, the Reuben ancestors' gift worked for her, and she transformed into an adult form, clad in his costume.
She was young enough that she hadn't yet developed much of a self-consciousness about being topless, and dove into the fray, much to the surprise and disadvantage of the bad guys altogether.
Once the bad guys were defeated, Rube asked who she was and why she was wearing his costume. She explained that age wasn't wearing it on purpose, she'd just called out to him, "Hey, Rube"—as soon as she repeated that call in her explanation, she transformed back. Recognizing his sister, Rube transformed back himself and explained what must have happened.
The next time she transformed, she was prepared and donned a short-sleeved top which became incorporated into her costume.
Since then, rikoffenberger
(aka "Joe Higgins") used Rube and Ruby on his latest "Agent Shield" cover:
