Captain Future and the Space Emperor by Edmond Hamilton

This was the first of a couple of dozen stories featuring the eponymous Captain, who goes around the solar system righting wrongs - in this case, liberating the grateful natives of Jupiter from the evil Space Emperor - with his allies, a brain in a box formerly known as Simon Wright, a robot called Grag, and Android called Otho, and a spunky gal from the Planetary Police called Joan. It's pretty formulaic but done with great enthusiasm.
