Each inherited superhuman abilities from a crowd of ancient heroes. However, while Red Rube's abilities, which he gained after saying "Hey Rube" were mostly physical (i.e. strength,durability, speed) and a smart noggin; Nature Boys gifts, which were derived from calling upon one of the "Kings" that bequeathed him his powers, were energy related (i.e. cold, heat, lighting, water, etc).
Oh and they were each a pair of blowhards. I mean literally. As in creating massive gusts of air pockets that projected them into battle.
