Back in 2014, Rihanna attempted to trademark Robyn for a magazine affiliated with Rihanna. DC Comics went to court to block the request of this trademark. Due to the boy Wonder Robin (with an "I") also known as Batman's partner in crime this trademark was not pursued.
If the magazine were produced, it would be a motivational magazine that looks up to strong role models such as Rihanna, to help the audience get through their day.
