Mastermind was shy as a young child, but as he grew up, he couldn't stop talking. He was adopted by the Pie family and looked up to his sister Pinkie Pie. She was his only color he had.
His talent is being smart. He is amazing at magic too.
He is clumsy at times, and sometimes a little arrogant, maybe even accidentally bragging.
