Brighton is a magical "Sun Spirit" who starts the fight in Mario Party 6. At the end of Mario Party 6 Twila, the "Moon Spirit", and Brighton agree not to fight anymore because they got into an argument about who was more impressive, Brighton or Twila. Brighton thinks he is cooler that Twila.
Brighton also makes a comeback in Mario Kart PlayPal, along with Twila as unlockable drivers. They were also proved to be quite popular characters!
