Tiara Boobowski, as known as Tiara Cyberooski and Princess Tiara, is a character created for the cancelled video games Sonic X-treme and Sonic Mars. She is an anthropomorphic manx cat created by Chris Senn, the lead designer for Sonic X-treme, who was also responsible for the concept of her father, Gazebo Boobowski. One of the four characters originally intended to be playable, Tiara was dropped when development difficulties forced the team to focus solely on Sonic the Hedgehog. Later, she was worked into three of the game's potential story lines. Chris Senn intended for her to be a love interest for Sonic in order to add romantic tension to the story. He had hoped that the story would show Sonic meeting his "match" in Tiara, but the stories the team developed had to focus on bringing together the levels and supporting a basic premise of good against evil.
