During the first few episodes of YAG, Marble is shown to have some intelligence, cunning, and also really observant, but is also sometimes enigmatic and breaks the fourth wall occasionally. She is also clever when it comes to creating ideas and forming methods at challenges. However, her personality started to become a more villain-ish and cold in Leaps of Faith. Her intelligent personality slightly weighed down due to her relationship with Bouncy Ball. She’s also a vampire.
