when did starfire get a brother

Okay, I don't know how true this is, but according to the Starfire Wiki: In Teen Titans Go! Issue #46 (a comic book spin-off of the original Fernsehen series), Starfire reveals that she has a younger brother named Ryand'r oder Wildfire. She explains to the Teen Titans that, when the Gordanians attacked Tamaran, her parents set up a ship to launch him to another planet in order to save his life. Afterwards, Blackfire, in an attempt to make a peace treaty between Tamaran and the Gordanians, give them Starfire as a "prize". (Setting up her appearance in the episode "Go!") As a result of Starfire and Wildfire's absence, their parents die of a broken heart. Wildfire seemingly comes to Earth to reconnect with his Sekunde oldest sister, but he is revealed to be the shape-shifting being Madame Rouge, who was hired Von Blackfire to deceive and kill Starfire as revenge. Discovering this, a furious Starfire personally visits Blackfire in jail and verbally cuts off all family ties with Blackfire (saying that they are no longer sisters), and swears that she will find her Lost younger brother, as he is the only blood relative she has left. However, this story was never continued, as the comic book series was canceled shortly after the release of this issue.
